the u.s. puts off tariff hikes on china. both sides say there's been progress in trade talks. and the crisis in venezuela. more soldiers defect after a violent weekend. also, no host. but the show went on. all of the highlights and surprises from this year's academy awards. live from cnn world headquarters in atlanta. we want to welcome our viewers from here in the and all around the world. i'm george howe.

cnn newsroom starts right now. 2:00 a.m. on the u.s. east coast. thanks for being with us. the president is gearing up for the meeting with kim jong-un. but much ahead of that trip has been on china and the issue of tariffs. president trump is tweeting that he is delaying a hike in tariffs in china, as progress is being reported in the trade talks. here's what mr. trump said sunday about a potential trade deal. listen. >> if it all works well, we'll have big news over the next week or two. and it's really been terrific. i tell you, that whole relationship has been outstanding. we put ourselves into a position of strength, for the first time in about 35 years or probably a lot more than that.

china is great. we want to make a deal for both countries and that's what we're doing. let's look to the markets. modest gains across asia. in shanghai, stocks have surged. president trump says on twitter he hopes to finalize a trade deal with a u.s. summit if there is more progress. our steven jong is following the story this day. given the little we have heard about, regarding progress of these talks, the delay of the deadline seems quite significant. >> reporter: that's right, george. not entirely surprising that mr. trump had been hinting that march was not a magical date. investors here in asia-pacific have responded positively to the news. and i think mr. trump hopes that u.s. investors will follow suit because the volatility caused by the uncertainty brought by the trade war is one of mr. trump's

major concerns. and some would say his eagerness to stabilize the u.s. stock market contributed to the decision to extend the deadline. and it is reflected in this leaguerness to cut a deal with china. still, in a pair of tweets, mr. trump ticked off all of the right boxes by talking about the structural issues in china's economy, that both sides have been addressing with these talks. property theft, and subsidies and key injuries in china. as well as foreign technologies here. all of these issues have long been u.s. demands in changes in china. many of the issues have related to how they view this economy should be run. with the extension of the deadline, it will be a tall order for negotiators to bridge

their gap and differences in the coming week. the momentum is here. and the deadline extension is welcome news for negotiators and investor s alike. >> the momentum is there, as you point out. but the united states is keenly focus to make sure there are levers, there are methods to enforce any sort of agreement. where do you see things going with that crucial point? >> that's really the key going forward from the u.s. perspectipe perspecti perspective. the chinese had made pledges before but failed to follow through. that's one of the complaints by u.s. officials, including mr. trump, who has blasted previous trade agreements with china. his work to set it apart from previous deals, mechanism or enforcement clauses are going to

be a top priority to get done before they can sign off on any version. >> steven jiang, live for us in beijing. we will monitor the news around the trade talks. the u.s. president will leave washington for vietnam, where he will hold a summit with kim jong-un. mr. trump, says he sees eye-to-eye with kim and won't rush things in these talks. >> the media will sometimes say, what have they given up? we've given up nothing. the sanctions are on. everything is on. but we have a special feeling. i think it will lead to something very good, but maybe not. ultimately it will, but maybe not. and i'm not pushing for speed but we're not removing the sanctions. >> president trump's summit with kim jong-un is one of the key

events that could have an impact on his presidency. the first on monday, security officials will release a letter slamming donald trump's declaration of a national emergency on the u.s. southern border with mexico. tuesday, the u.s. house of representatives, they are set to vote on the declaration, giving a glimpse of how much support his wall has within his own party. it will be interest and noteworthy to see how it progresses in the sessions, especially with republicans. and then thursday, michael cohen expected to testify on capitol hill. the president will be in vietnam when this is happening. michael cohen knows a lot about mr. trump and his business empire. but the president says he is not worried about what michael cohen has to say. we'll take a closer look at what this week means for mr. trump and for washington, with scott lucas, joining us at the bottom of the hour.

time to talk about the oscars. the big show is over. hope you got a chance to watch it and it was everything you would expect. there was the laughter, the tears, jokes and extreme fashion right there. and a few surprises, like diversity. how about that? there were notable representations of diversity, diverse filmmakers, actresses and actors. "green book" took home the best picture award. stephanie elam was on the red carpet and tells us about the big winners of the night. >> reporter: one of the big surprises is olivia colman winning for best actress for her role in "the favorite." everyone thought it would be lady gaga. listen to her speech. it was a really fun.

>> my kids are at home and watching. well, if you're not, well done. i sort of hope you are. this is not going to happen again. >> and just for the record, why people thought glenn close was going to win and people were upset on twitter nearby, is because glenn close's performance in "the wife" is stunning. it's stellar, and fantastic. she's been nominated before. she's never won. a lot of people were looking for "glenn close" to take that award. but olivia colman's speech was so lovely. at the end of her speech, she shouted out glenn close and lady gaga. throughout the award season, we have watched that everyone thought it would be christian bale and "the trajectory turn" and it was all about rami ma

malle malleck. he had a great speech. >> thank you, queen. thank you for allowing me to be the tiniest part of your phenomenal, extraordinary legacy. i am forever in your debt. >> one other person we were keeping an our eyes on, was a alfonso roman. that was talk that it would take that award. and that's just not what happened here tonight. alphonso did walk away with a couple of oscars, which is expected for this one. it is noteworthy. you're talking about a film in spanish. you talk about a women that is in black and white. and a personal story for alfoilo cuaron, as well. the big win that people were waiting for, it was the spike lee award. and people were waiting for spike lee to finally get his

oscar. that happened tonight. and he had a speech to remember. take a listen. >> the 2020 presidential election is around the corner. [ applause ] let's all mobilize. let's all be on the right side of history. make the moral choice between love versus hate. let's do the right thing. >> thanks for stephanie elam on the red carpet at the governors ball. now, let's bring in media critic, brian lowery. what a show. one thing i have to say, i noticed that difference, diversity, was on the sage this year. a sharp departure than what we've seen before. >> it's something that the academy has worked at. they expanded their membership and have been aware of it since the oscars #sowhite a few years

ago. the fruits of that and the winners, and the overall sense of the show, which was filled with nominees and presenters and people in color and women, in ways you haven't seen in oscar ceremonies in the past. >> it's nice to see, films, filmmakers, representative of the world we live in. you will remember the markets. they had roma taking best picture. turned out to be "green book," a film that's celebrated for its win and i noticed on twitter, a great deal of criticism, as well. >> "green book" is a very divisive film. i thought there was a good chance that it would end up winning. it looks like a lot of past academy winners. a lot of oscar winners have tended to be social area movies, period movies.

the two movies contenders, both with impediments to winning. one was roma, beyond the facts that no foreign language film has won. it was made by netflix. and the other was "black panther." there was a lot of heat behind that movie. it did win technical awards. for the academy, this is the first time a superhero movie has ever been nominated. and in a way, the thought was just being nominated was enough. >> "black panther" was a great film. i hated to see that. it was an interesting turn with the winner this night. let's talk about the category of best actor and actress. olivia colman taking the win for "the favorite." and rami malek, keeping in line.

>> the big surprise was olivia colm colman. if you've seen her, and watched her a lot of work in the u.k., she is a sensational actress. but glenn close has won every award building up to the oscars. that's when you get a sense that there's momentum behind a performer and they're going to win an oscar. and the other thing that olivia colman had working against her seemingly, was she was working with an ensemble cast. rami malek, other than christian bale as dick cheney, and you look at the performance and it's hard to know that's christian bale. if you like anything about "bohemian rhapsody," what you liked was rami malek.

>> how about the moment, director spike lee, winning his first honorary hos coscar. and getting that line of his speech, do the right thing. >> wit wit was great to have sa l. jackson giving the award. and the odds that spike lee and his collaborators were going to win. that's one of the more political speeches of the night, one of the more pointed speeches. there were a number of references to politics. most of them were vaeiled. you didn't hear president trump's name. you heard immigration and inclusiveness and a global community. that was the most pointed moment of the night. >> we appreciate your time and insight. thank you so much. >> thank you. a lot more to cover here. specifically, the border between venezuela and colombia. all eyes are on military

deflectors that you see here, being welcomed in colombia. that nation is now set to host a summit on the crisis. more details on that ahead, as "newsroom" pushes on. how much horse power does this thing got? doing great dad! looking good babe! are you filming? at booking.com, we can't guarantee you'll be any good at that water jet thingy... but we can guarantee

in colombia, there is a meeting that is supposed to take place between mike pence and juan guaido. this meeting comes on the heels of violent clashes along venezuela's border, the same place where troops blocked entry from desperately-needed humanitarian aid. more than 300 people were hurt along the border. the country's president condemned this weekend's violence. listen. >> translator: i think that the lima group needs to make a clear statement on what we have seen. i think the international community has an obligation to tighten the diplomatic reins because a dictator that is able

to withhold food from people on their own land, with such brutality, just to keep him in power. >> small clashes broke out on sunday against the venezuelan border. nick paton walsh has a take on there. >> reporter: this is where we were yesterday to see injuries, deflections from venezuelan soldiers who crossed the line from their hungry homeland and gave themselves up to colombian officials. it was a much lower temperature than we saw yesterday. and that is the problem that colombian authorities now own. they allowed this to happen yesterday. the aid that tried to get across failed. it hit riot police. there were clashes and a number of people were injured. while the top of the bridge appears to be more in control at this crossing, it's under the

bridge where opposition protesters are trying to make their way. they get really close. but then barrage of tear gas comes in. it's different today. colombian riot police, putting on the gear and running to the front to pull the protesters back. i think colombia now owns this situation. it may see in the weeks ahead, the protesters continually have a go at venezuelan military on the other side. of course, whether colombia wants that to continue or not is up to them, whether they lock this area down or not. yesterday, we heard of 60 military defecting. the venezuelan opposition, that number may have risen to over 100. some giving themselves up over the border duringing the nig it. there are those that see that as

the enduring scene, as the bid to get peaceful humanitarian aid across. the question now is what sort of response, promised by john bolton, will we see from the white house? nick paton walsh, colombia. let's talk about this with jennifer mccoy. jennifer, a professor of political science at georgia state university. joining us far from atlanta, georgia, in budapest. >> thank you. >> juan guaido, set to meet with mike pence in colombia. this is on the heels of welcoming dozens of military defectors from his native venezuela. how strong is guaido's hand right now, compared to nicholol madu madu maduro? >> maduro controls the security forces and the government institutions. but guaido has strong international backing. and the population is med up and

frustrated. i think he will continue to receive their support for some time, until they -- if nothing happens, they may give up. maduro, i think, showed weakness over this weekend because he seemed to have to rely on the gangs, as well as reports that he may be preparing prisoners to help turn back protesters. so, that shows a weakness if he does not have faith in his national guard and in his military, or if the deflections continue to grow. >> that would be significant, turning to prisoners to help out with his efforts there. with the threat of the united states getting military interventi intervention, how do you see things proceeding here, with the u.s. role in that region?

>> this is extremely delicate. the u.s. appears to be trying to intimidate the venezuelan military, with the threat of military intervention. the venezuelan military could not want a confrontation with the u.s. military. however, if the threat of intervention is not sufficient, and any actual intervention would be almost certainly repudiated by latin america, in general, just on principle. as you mentioned, the past u.s. role in the region. there's a risk, i think we have to keep in mind, though, of a clash on the colombian border, between colombia and venezuela. venezuela now closed that border. many of them depended on that border to cross daily for work and food and medicine. so, those frustrations will grow if that border remains closed.

and colombian stewaecurity, is one side, trying to help the people. the risk of a clash there could escalate rapidly. and the u.s. coming in to back colombia. i think we have several risks for armed clashes that we need to be very watchful for and careful of. >> with regards to the efforts to get humanitarian aid into venezuela. juan guaido promising to keep up the pressure. is the pressure campaign making a difference for him in this tug-of-war? >> he said that the aid would come in and he wouldn't able to keep that promise. that dashed the hopes of some venezuelans that believed it would happen.

the sanctions will continue to bite deeper and deeper. maduro closed his transit routes with brazil, colombia and the three caribbean islands nearby. that hurts him and venezuela, just to be able to import the food and the goods they need. this pressure will grow. now, the meeting today, there's concern that they will be discussing military convention. some are brought up the right to protect, which is an international commitment of all states to protect their citizens. if they violate that, the u.n. in the past, in the case like libya, has authorized military intervention. i don't think we're there yet. there must be -- for that to be invoked, there must be exhausted all diplomatic solutions, as well as sanctions.

so, we also have the international contact group who is attempting to facilitate elections. >> and clearly, the pressure will continue. we'll stay in touch with you as we keep watching. jennifer mccoy, thank you for your time. >> thanks. still ahead, is it progress or posturing? we'll review this week's summit between the u.s. and north korean leader. korean leader. what might come of it? when you switch out an old car part.$200 but you do when you switch to jackson hewitt. at jackson hewitt we help lots of people like you. that's why you get $200 when you leave your old tax service for us. so switch to jackson hewitt today and get $200. at panera, we treat soup differently. with vine ripened tomatoes, signature cheddar, simmered to perfection. with big flavors, not artificial ones. enjoy 100% clean soup today. panera. food as it should be.
