we have jill dougherty in moscow and ivan watson in hanoi. let's talk with nic robertson. nic, we saw the presidents. trump and putin crossing paths several times. we hear from the kremlin on the joint statement on syria. what more can you tell us about the substance of the statement? >> reporter: george, it is interesting we have not heard anything from the white house about this meeting so far. what we have seen is that when they sort of been in the same room they have shaken hands and few words exchanged. president trump or president putin walking to a photo op. nothing we were aware of. no pull aside. no bilateral meeting. it is odd the white house isn't commenting on what russian state news is saying and the headlines
