"The issue of denuclearization of the Korean Peninsula can be resolved", Kim was quoted as saying, "if South Korea and the United States respond to our efforts with goodwill, create an atmosphere of peace and stability while taking progressive and synchronous measures for the realization of peace".
If China prepares an emergency exit for the North again, there may be no necessity for any summit meeting between the two Koreas or that between the US and the North.
"The joint concert is meaningful, but watching just the performance by the South is also meaningful". Trump seems to be saying that if North Korean leader Kim Jong-un does not show a clear willingness to follow through on his pledge to scrap his nuclear weapons, the US will put greater trade pressure on South Korea.

The South's 160-member art troupe will again perform April 3, this time alongside North Korean counterparts, before returning home.
"The North's audience applauded our performance much louder than we expected and even sang along to our songs.it was a big relief", band member Yeri told reporters.
