taken place here along the dmz. >> absolutely. credit where due. you can see these pictures. i was there in 2013 under a had to wear a flak jacket, a helmet. you have the u.s. president standing there, very little protection there, no helmet, no flak jacket. he's being briefed on what exactly is happening. standing there with the south korean president and that is dwijtdly progress. >> yeah. >> we're not in 2017 when there was constantly nuclear testing. there is definitely some progress. >> another sign perhaps of how protocol, normal practice has been upturned. jim acosta reporting that it was the president's tweet yesterday inviting kim to the meets at the border. that's when officials got into high gear to make this meeting between kim and trump a reality.

please stay with us. we're going to bring that moment to you live here. i'm jim shuciutto here at the d, demilitarized zone dividing south and north korea as it has for 66 years. tremendous array of power along the border. as we watch these live pictures from the dmz, this is the location where the u.s. president and the knot north korean president will meet. the president said yesterday, he would be willing to step across something that the south korean president moon jae-in did months ago when invited by the north korean leaders. this is the dmz where the president is arriving, you see the vehicles there.

the south korean president has joined him and we're waiting where shortly where the north korean dictator, kim jong un will join them for this historic moment, this unpress dented moment of a hand shake between the two. paula, as i've noted before in 24 broadcast, you have been to this location here where this will take place. cry it to our viewers. describe the array of forces there. describe what it looks like and the history behind it. >> that was the observation post that we saw the president at with president moon jae-in. that gives you a good overlook of the whole of the dmz and into north korea. it will be a short drive down to the truce village where we assume he'll meet with kim jong un. this is an area where in the past we've seen north and south korean soldiers face off against

each other. it's an area where you have the blue huts where in the past, there have been agreements made and it's also the area where you see tourists good to. you can go inside one of those tents and step across into north korea. >> would there have been negotiations, battles between whose flag is taller. you mentioned houts a short drive from the observation post where we saw president trump and the south korean president a short time ago, a short drive to the truce village where we believe the meeting will take prays with kim jong un. we saw the vehicles making the move from the observation post down to where the meeting with kim will take place. anna corin, our colleague is in seoul. describe the tweet by the president that seems to have

sparked this whole idea which is now in a short time going to become a reality. how surprised were they about it? perhaps how stressed were they by the prospect of making this a reality and how would the north koreans reacted to that? >> certainly, jim, i think there's no denying that it probably caught everybody off guard, including the south koreans. this is something that the south korean president moon jae-in has been wanting. so obviously delighted. we heard from him speaking at the blue house behind us before setting off for the dmz that if trump meets with kim, it would be a nile stone for humankind. you have to assume it's slightsly overreaching, but it gives you a sense of how important this moment is to south korea. they have been pushing for peace

on the korean peninsula and now they feel that there is momentum. obviously, the talks stalled back in february in hanoi and the north koreans were angry with the south. they feel that they are limited as to how much they can actually achieve with the united states. hence, you see the north koreans playing to the south korean, we don't want you to immediate ate on our behalf. we will deal with the americans directly. that puts them in control, in the drivers seat and that plays to everyone back in north korea that it's kim jong un in control, not the south korean president moon jae-in. the feeling here in full certainly is one of hope. people are hopeful that this will lead to a third summit, something that hasn't been dismissed.

obviously president trump to see how today's meeting goes. the president himself said that this is going to be a very short meeting. the hope is that this resets the relationship and that the two countries can start negotiations, start getting the denuclearization plan back on track. jim, i think it's important to remember that ever since the singapore summit according to analysts north korea was developed half a dozen nuclear war heads. that adds to their arsenal of some 60 to 70 war heads. north korea hasn't done much, if anything, since donald trump began speaking to kim jong un towards denuclearizing north korea. there is a lot at stake, a lot riding on this. it can't just be style over substance. >> yeah. well, it's an important point, because this is not frozen in time. as these negotiations have gone

on, without progress on denuclearization, doesn't mean that the north korean program stays in place. it is, as you said, making progress. advances in the missile system happens as the talk stall here. this meeting today, the expectation really to have the meeting happen. the president defining success tazz neegt taking place. this is not a negotiation today. it is simply a face-to-face hand shake, a hand shake at the border. a brief note about what's happening next year. the president a short time ago went to what's known as the observation post there where he could look across into north korea and look at the array of forces there defending the dmz. he's now gone down closer to the truce village where he'll be face-to-face with the forces. u.s. forces deployed in south

korea to help protect south korea from the north. then in a short time he will meet the north korean leader kim jong un face to face with a hand shake, perhaps with the possibility of setting foot into north korea if given the invitation by the north korean leader. i'm joined here at the border by paula hancocks. a tremendous amount of choreography in what is happening now and the next steps. a little bit of showmanship as well. >> when you say it's going to be north korea going to be a part of this, it's the most choreographed. there are no images of kim jong un that come out that he doesn't want people to see. it's heavily vetted. these kind of meetings, he can't control as much. he can't control the message going out. what electric do is take this back to his people and show the rest of the world the u.s.

president has come to the dmz, has come to my doorstep to see me. >> the north korean leader is not someone to take spur of the moment trips. he tends to go by train as opposed to by air. he likes having attention to security, preparations, etc., so to respond to a presidential invitation via twitter and within 24 hours show up at the border, describe what if headache is the right term or surprise and shock people around him had to make something like this happen. >> it's unpress denltsed. this is not what north korea does. the u.s. president himself said yesterday at least we know the kim jong un follows him on twitter.

the quickest response from anyone from north korea that i've ever seen. it usually takes a day to react. that was incredibly fast. >> we're looking at pictures from a moment ago from the dmz, the president describing the scene he saw. also taking as we've noticed this three or four times in the last 20 minutes or so, taking some shots at the press coverage, saying that the press is not giving him credit for the negotiations. of course, it's his own administration who defines success as denuclearization by north korea. moments from now we wait for that face-to-face meeting between president trump and kim jong un. stay with us. we'll be right back. if you live with diabetes,

. i'm jim sciutto at the demilitarized zone between north korea and south korea where president trump will meet with kim jong un in moments. the location is an historic one, right on the border of the truce village separating these two countries, that point on the border separating them for some 66 years since formal conflict between the two of them.

you're seeing president trump at the observation post at the dmz just a short time ago. he's going to meet with u.s. troops, south korean troops as well at the border before that hand shake with the north korean leader. we'll bring that to you live. my colleague anna corin is in seoul covering the events live, including a meeting between president trump and president moon jae-in of south korea. >> it is an important moment because south korea's president has been working behind the scenes to try and get negotiations back on track. in fact, the north koreans have shunned the south koreans, if you like, a little bit dirty what happened in than hanoi. different expectations as to what can be achieved and what

needs to be done to move forward. obviously, there is great symbolism attached to this meeting between the u.s. president and the north korean leader. we heard from south korea's president moon a short time ago saying that this is going to be a milestone for humankind. overreaching, perhaps, but it gives you a sense of how important this is. to discuss this more, the add jungt for security. obviously, critics are saying this is theatrics, a photo opportunity, nothing concrete. here on the korean peninsula, south korea and north korea, this counts for something. >> i agree with the critics. the two koreas, especially when there was a diplomat lull after hanoi, very awkward situation

between washington and pyongyang. the exchange of the two love letters. now the hand shake at the dmz basically shows that the bromance between trump and kim is going quite well, even if the countries might still be at odds. >> we heard them lambasting washington and low-level officials. yet it doesn't seem to affect trump and kim. why is that? >> they're separating the leader level and the working 4re68. basically they're trying to say that as long as we're at the leader level dealing with trump directly, everything is fine. once we talk to the working level to pompeo and others, they're calling him the head for interfering with the relationship between trump and kim. >> how then does this progress. if you're not going to hand it over to the people delegated to try and reach an agreement to

denuclearization, if you can't trust your own people to talk to your counterpart, how does this move forward? >> right. and they have a lot of work ahead of them to prepare for a third summit. now i really don't think we can afford them to have -- i don't think they can afford to have a third summit without the proper work in place. that means really getting down to discussing even if it's scenarios on a possible deal and compromising bargain on the way forward. without that, if the two leaders meet again without putting in the work at the working level nks it's going to be hanoi all over again. >> how does the u.s. walk it back they've said from the outset it's denuclearization. how do they compromise? >> one way for the north to be dpleksble is for them to agree on a general roadmap on where this all ends, how do we get to

zero nuclear weapons and a bit of compromise, flexibility on north korea's side would be to agree to some sort of a fazed approach step by step implementation of the process. >> zero nuclear weapons, is that even a reality? of course, that's the end goal. but is that a reality? first, before we answer that question, we're just looking at live pictures of the u.s. president meeting with members of the u.s. military -- or the south korean military. let's take a listen. [ applause [ speaking foreign language ]

>> translator: you are standing at the fore front where you are safeguarding peace and freedom of the koreas. [ speaking foreign language ] >> it is actually the first time in history that the president of the republic of korea and the president of the united states has advisemented in history in this zone. and today this afternoon we have a more dramatic event that awaits us. [ speaking foreign language ] >> and i'd like to thank president trump for making such a bold decision. [ speaking foreign language ]

and now joint security area is being transformed from the symbol of confrontation and hostilities to a symbol of peace and all of you are actually witnesses to this great change. [ speaking foreign language ] >> and the very person who has actually brought this change about is, of course, president trump. [ speaking foreign language ] >> he is the president of all of you. [ applause ] >> i want too thank you very much. you're a special group of people. i look at you, look how healthy

and strong and how good. we really preach it. we preach it very much. appreciate it very much. [ speaking foreign language ] . >> so this was a scheduled visit from a number of months ago. we went from the g20 and i promised your president, president moon, who is a friend of mine, i said we have to see the dmz and so this was scheduled for a long time ago, and then yesterday i had the idea maybe i'll call chairman kim and see if he wants to say hello. so we didn't give him much notice, but we've become -- we respect each other. we respect each other. maybe we like each other. and he's agreed to meet and i'm going to meet him in about four minutes, so i'm going to cut my speech a little short, other than to say you're terrific people, you've done a fantastic job and we're with you all the way. you know this.

[ speaking foreign language ] >> what do you have over there? that looks good. >> we have a small token of appreciation for you. we're grateful for your leadership and president moon and what you do for the alliance. we have a small token of

appreciation. everybody knows you're a golfer and there's some golfers in the room. so we got you -- we're hopeful -- i know you get a lot of gifts but this one was one that might find some utility for you on one of the golf courses. it's got your name stens i would on is there. it's got all of our command forces on there. so it's got your name on there. it's got -- it's -- of course, this is the most important one because our motto is here. when you wear this on the golf course, we hope think about this. thank you very much. >> thank you. [ applause ]

>> you've been watching live pictures of president trump and president moon jae-in of south korea meeting u.s. and south korean forces stationed here at the border between north and south in the dmz, 30 u.s. service member, 30 south korean service members. a moment ago, the president reaching a gift from the commander of u.s. forces, something they said he would wear on the golf course, a jacket for him to wear noting the units that are deployed here at the border. we're joined by joseph yurvegs n, a cnn global affairs analyst who crew shally served as special representative to north korea. he had experienced negotiations between these two countries before. joseph, it's always good to have you on this broadcast because you've experienced this relationship firsthand. you've participated in difficult negotiations with between these two countries firsthand.

i want to ask you this question. the president meeting here face-to-face with the north korean leader, certainly significant. does that normally serve as the predicate for substantive negotiations or would it normally come after some sort of agreement is made? >> of course it normally comes after some sort of agreement has been made. so while it is very, very symbolic and quite historic, if nothing happens afterwards, then it's just here. that's what i'm concerned about, jim, and we've seen one failure in hanoi. if only thing the two leaders do here is just shake hands, then i will be very, very disappointed. i think at minimum, at minimum, the meeting today has to kick off a major process in which two

sides agree to make some significant progress on desnoikization and building relationship with each other. if it doesn't, it's going to be like hanoi and everyone will be very, very disappointed, jim. >> as you were speaking, ambassador, we saw the president participating in the ritual of signing the wall there in the u.s. post along the dmz. these pictures you're looking at or moments ago when the president was speaking to u.s. and south korean forces there. ambassador yun, in moments we're going to witness something that's never been seen before. u.s. presidents have come to the border before but not come and met with the north korean leader kim jong un who may very well invite president trump to step across the border as he did a couple of months ago when the south korean president came

here, too. tell us of tthe significance oft moment? how significant, how unprecedented? does it matter? >> i mean, ok. it matters if there is a goal to it. it matters if we are trying to do something. quite honestly, jim, at this point, i'm not sure what it is that donald trump, president trump is trying to accomplish. because why all this engagement has gone on, it has nothing to do thewith the stockpile of nuclear missiles. in fact, they increase them. we're in for a roller coaster ride. yes, it is true that tensions are down. remember, the tensions were built up because all the fire and fury during 2017. so really, i mean, you know, we've been on a huge roller

coaster ride and i hope there is a method and there is a goal on what today's meeting will lead to. >> is it fair to say that during the months of these summits and now a hand shake greeting that north korea's nuclear program has advanced rather than stood still? >> of course, the program has advanced. they've advanced because they've been able to stockpile more nuclear weapons, both through their plutonium program and their enriched uranium program. they've been increasing, and the estimate is that every year that the program is not frozen, an increase between five to eight nuclear weapons. there's no question that researches continue as well as

enrichment of plutonium and the missile site. they do the president a real danger and it is growing. >> joseph. >> we are moments away, we can say. minutes, we believe, now from the moment that we've been waiting for. there's a hand shake, face-to-face meeting at the border between president kim jong un and donald trump. we're going to bring that to you live as it happens, just minutes away. joseph yun, you've been involved in the preparation for high-level meetings including a special represent yi6 of course for the u.s. president. what are president trump's advisors telling him right now in the minutes he meets face-to-face with kim jong un? >> i think the minute he meets face-to-face, i think it is very important that denuclearization is the foremost goal. so you see, one thing that president trump has gotten into over the last few months is

there is two issues, denuclearization and peace. so now, you know, he's getting into the north korean fair tifr, which is that we must have baes before we have denuclearization. why the american position has always been that we must have denuclearization first before we have peace. so this is the two -- two things, two important factors there are and you can see that increasing president trump is buying into north korean idea that yes, let's build peace before denuclearization and that's not been the american goal nor has it been the south korean goal. they've always felt that as long as nuclear weapons, north koreans have nuclear weapons,

both south korea and our key ally, japan would be under threat. so we are seeing a transition in the mind of donald trump. but remember that there's a big gap between u.s. president and his senior advisors, john bolton certainly doesn't buy into it. neither does mike pompeo. so you're going to see this conflict that has been played out, continue to be played out. as far as kim jong un is concerned, of course, if he can get with donald trump, so much the better. and this is why they've been hurling insults at john bolt oen and mike pompeo but also being very flattering and nice to president trump. >> i don't think we can underestimate or emphasize the backdrop for this moment that's about to take place. certainly, symbolic sign of

peace. but the backdrop being hundreds of north korean artillery pointed at the south principally kargting seoul, some with keps and now a nuclear armed north korea, placing south korea under threat. that is the fact of the standoff, the 66-year standoff between these two countries, where you now have a u.s. president waiting to meet the leader of north korea. there's a remarkable juxtaposition of that threat, that danger and what will be at least on the surface, smiles and a hand shake between the north korean leader and the u.s. president. jim acosta has been traveling with the president. jim, it was interesting in the moment so far up here at the border as the president prepares to meet kim, i counted three or four times where the president took a swipe at the press,

claiming he's not getting the credit he deserves for the outcome of these talks so far. not unusual approach for this president, even as he prepares for such an unprecedented moment. >> that's right, jim. you heard the president there speaking a few moments ago in full view of the camera saying after his first summit with kim jong un in singapore "the danger went away." of course the danger did not go away but he's made these sort of statements, posted these kind of tweets ever since the meeting with kim jong un in singapore last year. the critics and fact checkers have pointed out that that's not the case. he continues to say it. you get the sense that the president is sort of gathering this grievance with him that he doesn't get enough credit for where things stand with north korea right now. as his critics point out, the

reality tv theatrics does not stand in place of denuclearization. the peninsula still faced with the north korean dictator and its regime and its arsenal. i do think it is fascinating, though, jim, the relationship that exists between president trump and kim jong un. he just said a few moments ago we respect each other, maybe even like each other. he's gone further than that. he's talked about this being a love affair and how they've exchanged these beautiful letters over the last couple of years. clearly he's developed a rap oar and relationship with kim jong un. it goes back to the question we've raised, why he has cozy dictators around the world. this may be one of the coziest relationships he has with kim jong un. he's banking on the fact that

these kind of permanent appeals will yield some progress at some point. it's obviously not going to occur at the dmz meeting they're about too have in a few moments, but he is hanging so much of his legacy on these interactions with kim jong un he is essentially leading himself to believe this is going to bear fruit but there seems to have been no progress up until this point. what we're seeing is essentially just another hand shake that and a greeting with the dictator which the president has excelled at since he's been in office. >> behind the smiles as we watch kim jong un in moments here is a man who has killed mechanics of his own family, he used a chemical weapon to assassinate his own brother, who holds thousands of political prisoners

and who starves his own people. we have to remember that as we look at this moment here to come. i'm with paula hancocks at the dmgz, a short distance away from the truce village as it's known. i wonder if you could help us out. people are going to see some remarkable nikts the coming minutes. just the architecture of this site where they're going to meet. the blue hut where past negotiations have taken place. describe for people. >> from the south korean side you come out of the south korean building and straight ahead you will see on the other side of the mdl, the north korean equivalent of that building. if president trump and kim jong un decide to go in and talk, do they go to to south korean side of the north korean or do they pick a blue hut.

there are several blue huts on the exact bored between north and south korea. until president moon jae-in stepped across that border with kim jong un back in april, a fair while ago now, we haven't seen that lap from a south korean president, the potential that we could actually see this as the u.s. president as well. he's said he's very comfortable with that. >> something you cited earlier, a tamping down at least at this border where the forces come face-to-face. just let me take a moment before i reference that. these are live pictures again from the dmz there. you can see the road, i believe, leading up to -- >> this is coming up. >> there it is. >> yes. >> known as the jsa. i believe we can see the blue huts you were referencing. >> on the left-hand side side is south korea and on the right-hand side that is the

north korean building. in between the blue huts in the middle is that mdl, the military demarcation line. >> that there? >> it's halfway between those blue huts there. >> ok. >> you can see on the other side, the north korean soldiers. you can see the press jostling to get into position. >> we saw the president's secret service there checking out the scene. you can only imagine the challenge they face, the president entrusted with keeping the president safe who at times has had snipers, etc. i'm sure the president received security assurances before coming. if you can see, the blue hut on the right and on the left. there is a line there in the middle ground. that is the border.

the 38th parallel that divides north and south and has since the formal end of hostilities in 1953. we should note officially that war is not open. it's an treat. that could be a step perhaps between now and if north korean were to make any substantive steps towards denuclearization. looks like we're losing the signal momentarily there. that is where president trump will meet with kim jong un. it will be the moment to see. i've covered a lot of stories in my decades as a form correspondent. we shouldn't underestimate what a moment this is but for the viewers at home and around the world to witness this hand shake

diplomacy, you might call it. >> we saw the dml. it's the most unassuming border on effort. it's a slightly raised piece of concrete, very easy to step over it as we saw with kim jong un around president moon say in. what it represented up until a year ago, you could not step over that border. if you did, you would likely be shot by the either the north or the south korean side. it could very well have been a steel barricade. >> the famous incident of a north korean soldier defecting. shot at by his own comrades and barely surviving. >> that was just a few meters from where we are now. >> we expect president trump to -- you're looking south

there. when the camera pans to the left here, that's looking, well, somewhat down the border. it's a little further out of frame there to the left. and north korea as you're looking at your television to the left. that is the point from which kim jong un will emerge and the u.s. president walking towards him. again just minutes away there. you see the traveling press. they're ready, they're in position. we've seen members of the president's security detail, the secret service, their presence as well. our anna corin has been watching this. you've covered this region for some time. the importance of what we're about to witness here? >> there is no denying that this is an enormous moment. it will be a hirveg moment. it's very symbolic as well. as we're speaking with our previous guest, she said symbolism is just crucial to

those in south korea as well as in north korea. so whilst the critics are saying where's the substance, where's the concrete plan for denuclear sayings, as far as the two koreas are concerned, just by shaking hands, donald trump meeting with kim jong un on the dmz, that alone stands for so much more. obviously, the u.s. sees this as a potential reset on relationships. in february in hanoi talks an bruchtly ended. the united states feeling that the south koreans -- i beg your pardon -- the north koreans were inflexible and donald trump left the meeting. there was a breakdown in talks. the united states has tried to re-establish talks. obviously, the u.s. special

envoy to north korea, steven bag an, he has also made numerous attempts to reach out to the north koreans. it hasn't gone anywhere. so really, this is donald trump doing diplomacy his way. this is his style. he believes -- he's really the only person who can move this forward and perhaps that is very true. he gets the attention of the north korean leader. he can send a tweet and summon the leader to the border. so this is obviously a very important moment, jim. but as we've been speaking throughout the morning to experts in this region, they say there has to be so much more, for sure. this is a hand shake, hand shake diplomacy, as you mentioned, but it has to foul. there has to be more, because otherwise, it's really not going

to progress any further than where we are. >> right. and as you're speaking there, we are looking -- the doors you're looking at there, the glass doors, this is from the south korean side, southern side of the border. those are the doors from which president trump will emerge shortly, walking north towards the line that separates north from south and presumably kim jong un walking from the other direction, north korea and we expect this to happen at any moment there. we've seen members of the president's secret service detail there in advance. they've been laying the groundwork -- and here comes the president walking north from south korea.

>> be to see you again. >> i never expected to meet you at this place. >> translator: over to this side. >> you're the first u.s. to cross the border.

>> take a picture here? no. >> hey, hey, hey. >> come on. >> come on. >> big moment, big moment, big

moment. tremendous progress. >> ok. come on, come on, come on. >> go, go, go. >> go straight, go straight. >> allow do you feel? >> doing great.

>> chairman kim, how do you feel? >> translator: president trump came up here and physically stepped foot on to our north korean soil. this is a historic moment. this action in itself, you should not be looking at just the able to but this has a lot of significance, because it means that we want to bring an end to the unpleasant past and try to create a new future, so it's a very courageous and determined act. . >> i said hey, i'm over here. i want to call up chairman kim. and we got to meet, and stepping across that line was a great

honor. a lot of progress has been made. a lot of friendships have been made, and this is in particular a great friendship. i just want to thank you. that was very quick notice, and i want to thank you. [ speaking in korean ] >> so we're going to go inside. we're going to talk for a little while about different things, and a lot of really positive things are happening, and i'm glad you could be here to see it. tremendous positivity, really freig great themes aings are happenin lot of places, but we met, and we liked each other from day one. and that's really important.

[ speaking in korean ] >> thank you, everybody. thank you. i would invite him right now to the white house. >> guys, back! stay behind me. everyone behind me. >> back, back, back, back, back. >> well, ladies and gentlemen, ladies and gentlemen, we've just witnessed quite a moment there. president trump walking across the border from south korea to

north korea, greeted by the north korean leader kim jong un, followed very quickly by kim jong un, crossing the border from north to south, welcomed by the u.s. president, donald trump, and just for a moment there, both of them side by side, shoulder to shoulder, speaking about each other and this moment. president trump called it a great honor to step across the border. he said a lot of progress has been made. he said about his personal relationship with kim that we met, and we liked each other. and he said that that is very important. kim jong un also a rare opportunity to hear directly from the north korean leader. he said that this has a lot of significance in this, in his words, that it means that we want to bring an end to the unpleasant past. he also praised the u.s. president as courageous for making this moment happen. here's president trump speaking.

>> behind the security detail there president trump and kim jong un of north korea still next to each other. this is on the south side of the border, just yards from the north, i think we can hear the president's voice there. let's have a listen for a moment, see if we can make out what he says. >> just the opposite, it's my honor and the chairman's honor. i can say we work well together. mr. president, thank you. [ speaking in korean ]

>> yes, absolutely. >> translator: i would also like to take this opportunity to express my -- [ inaudible ] >> all of us together. yes. back to the yellow line. back to the yellow line. >> hold it. >> there we see president trump. kim jong un of north korea, moon jae-in of south korea. we've just witnessed a remarkable moment. president trump as kim himself said when he stepped across the border, said you're going to be the first u.s. president to cross.

president trump accepted that n invisitation, stitched across the border and then shortly thereafter kim jong un stepped across the border to south korea. president trump just told reporters that he and kim are now going to have a more private conversation. this is the moment a few moments ago when president trump took those fateful steps across the border, that line he's about to step across here, that is the border itself. and you can see kim jong un approaching from the north there to welcome him. the words he spoke to the u.s. president as he did cross were, you're going to be the first u.s. president to cross, and indeed he was. this is the moment, as they shook hands there. >> good to see you again. i never expected to see you at this place.

step forward. are you the first u.s. president to cross. >> good to see you again. i never expected to see you in this place. those were kim jong un's words to donald trump as he walked across the border there and spent, well, a few seconds, perhaps a minute or two in north korea, as he made history as the first u.s. president to cross there. just some news we have in. we learned that president trump has now invited kim to visit the united states. an invitation he extended in the moment there, moments after kim walked across the border to the south. these images from just moments ago. >> hey, hey. ho, come on! >> wait until they move! wait until they move! >> thank you, mr. president. >> joseph yun, a senior global

affairs analyst, describe your reactions to what you just witnessed here. >> it is, of course historic, very historic. not just kim jong un and donald trump but moon jae-in as well. those three people, and having it in dmz is of course very meaningful. that is the divide, of course, between north and south korea. the result of a second world war when the division took place. so it is very historic, and you can see the relations between kim jong un and donald trump, indeed very warm, very friendly. i mean, my, my question is can that be translated into some progress so that north korea makes a significant move on

denuclearization. remember, that is the problem. and that is the problem we've had for past two and a half decades. and now you can see them going in for a conversation. i mean, let's hope they talk some substance, you know? let's hope they talk some substance, because in hanoi, they had some offers from both sides. and, you know, jim, you and i were in hanoi. we weren't surprised, very surprised, when the talks broke off that there was something on the table in hanoi. the crux of the matter seems to be how much can kim jong un do on denuclearization and how much can donald trump do on sanctions? remember, they have offered yongbyon. and remember, the problem with just yongbyon is that we've paid for it twice before. once in mid '90s when we had agreed framework. and then second time during the six-party talks.

so, if you talk to the expert, both in south korea and u.s., they fear yongbyon by itself is not enough. especially when we know for sure that they have other nuclear sites, specifically -- >> ambassador yun, these are live pictures. these are live pictures from inside a bilateral meeting. trump and kim. let's listen in. [ speaking in korean ] >> translator: i return surprise to hear about your offer on the tweet and only late in the afternoon i was able to confirm your invitation. yesterday morning, when you expressed the willingness to meet with me here, and also when

we go to the official communication late yesterday afternoon. >> translator: i had wanted to meet you again. and especially for both koreas. it is a sign of unfortunate history of the past. so for our two koreas to be able to have this opportunity for me to meet you here is very significant. this means that we can feel at ease and meet each other with positive mind-sets. i believe that this will have a positive influence in all of our discussions in the future. . >> translator: a symbol of the separation, but also a reminder of unfortunate past and the two countries with their long, unfortunate past as this place shows that we are wli
