let's speak to professor robert e kelly — he's an expert in the koreas at pusan national university.rom south korea. good morning to you. how should we greet this announcement, do you think? i think the response globally has been correct, which is guarded optimism. they are saying the kind of things you want to say about nuclear weapons, about the south korean alliance with the americans, about nuclear exercises. we don't wa nt to about nuclear exercises. we don't want to get carried away on whether or not they do this, it will have to be verified, which means inspectors which they have been a cost per with in the past. it is better than it was just a few months ago. it is as good as what they say it is, it is not a bad step. how much has it cost them in the sense that some commentators have made the point that they don't need to do all the testing, they have done what they want, there don't lose anything to offer this up. in the short-term, thatis offer this up. in the short-term, that is true. the good news is that the north koreans seem to have stopped with a basic fission device,

professor robert e kelly is an expert in the koreas at pusan national university in seoul. think today, the response globally has been correct, guarded optimism. things they want us to say about nuclear weapons, the south korean alliance with the us, about military exercise. obviously, we have had trust issues with them in the past, so we trust issues with them in the past, so we do not need to get carried away. inspectors in north korea have to verify, which they have been uncomfortable with in the past. but it isa uncomfortable with in the past. but it is a lot better than it was even a few months ago, so it is as good as what they said it is. it is not a bad step. i guess the north koreans will start to ask for some kind of concessions. they have given stuff, at least rhetorically, the last couple of weeks. they have stopped objecting to the exercises and the american forces in south korea. all these things will be understood as concessions/ glass for something. i think generally they will ask for sanctions relief in some sort of economical operation. we know they are de

let's get more on the joined by professor of political science and diplomacy at pusan national university and he's joining us live from busan very good to have you as always with us on there mr kelly the dolls and to testing automatically results in that verifiable dismantlement that they mentioned off the. nuclear and missile programs. yeah that's the big trick right i mean if they stop that's great if they really do start to tear down the infrastructure that's even more great i don't think we should underestimate the importance of what happened today but ultimately the real issue as usually is the case with deals with north korea is verification right the north koreans impose great things in the past and then it doesn't really come through sequencing particularly as an often an issue who goes first and stuff like that in this particular case we would probably want to make sure that international inspectors got into north korea and actually looked at things and maybe we can put in some cameras and stuff like that the north has traditionally been uncomfortable with that and so my guess is

friday summit between the two koreas robert kelly is a professor of political science and diplomacy at pusan national university joins us now live from seoul good to have you with us again robert lot of optimism thank you surrounding this this this summit on the on friday do you share that optimism. it's a good start it's certainly not where we were six months ago when we're talking about nuclear war the rhetoric has improved dramatically the tone is a real improvement that's good to see i think the real question going forward is will the north koreans actually do what they said they would do yesterday this is where these kinds of summits and declarations have collapsed in the past you know sort of good principles and unseated but then no follow through and that's ultimately where north korea has to move there's got to be some concessions from north korea or we're going to be back where we were a year ago talking about missile defense and sanctions and stuff like that the remarkable pictures yesterday the the two leaders kim jong un appearing right particularly relaxed what has brought the n

kelly, an american political analyst of inter-korean affairs and professor of political science at pusanniversity in south korea. his latest piece for the guardian is titled "north korea's nuclear pause -- grist for both doffs and hawks." professor kelly, what most explains the change we've just seen? >> i think the long-term pressure of sanctions, i think particularly the president has pushed china hard on this in the last 16 months or so. we know that china is the most important gateway for north korea to the global economy. the north korean economy, despite its talk is really -- and needs external contact. it puts pressure on the elites. and the president has pushed china on this a lot and the bellicose rhetoric scared the chinese and they are taking this more seriously than in the past. >> so you think the bellicose rhetoric had an impact on the chinese, and the chinese then leaned on the north koreans but you don't think -- you discount that trump's rhetoric had an impact on kim himself? >> it might have but there's really no empirical evidence to prove that one way or another. it's
