leaders to discuss, right at the top of the list, obviously is north korea. president trump has been expressing his frustrations over the last several days, essentially saying that well, i tried to work with president xi on this issue of reining in north korea. but they keep launching these missile tests and so on. in the last few days, the president said well, i tried. now we should point out during this foreign trip, the president was asked, are you giving up on working with president xi when it comes to north korea? and he said no, never give up. i think it will be interesting to find out what the body language is going to be like as all of this information comes in. and what exactly is said, if past is prolog, there may not be much substance that's said in front of the cameras, as we've noted in a lot of the bilateral meetings, when the press is allowed in and they allow the press to take pictures and videos there isn't a great deal of substance, we have to rely on officials after the meetings are over to ascertain what happened.
