deadlock there. donald trump has been hinting and the administration has been hinting that china need to do more. china at this stage is showing no willingness to do that. it can. it does have economic leverage, a lot of economic leverage. we know that something like 90% of north korea's international trade is done with china. china at the moment is saying we abide by all the u.n. resolutions about sanctions towards north korea and that's where we are at the moment. we believe in dialog, both putin and president xi saying that dialog was the next step forward. for that to happen it says that the u.s. has to stop these military drills with south korea and that north korea has to freeze its nuclear programs. neither of those two things look likely happening certainly at this stage. >> that's right. as per china's willingness, trade up 37% between north korea and china in the first quarter. thank you.
