US President Trump said at the US-China summit that he promised "100% cooperation" on North Korea.

The statement is said to be aimed at bolstering cooperation with the US and North Korea in response to a ceasefire in trade talks, as the US and the Middle East are perceived as a way to ease sanctions on North Korea.

President Kim Jong-un said he is reviewing three places in relation to the issue of holding the second summit with the North Korean state secretary.

Currently, the first summit meeting between President Hamid Truff and the United States is being held in the Asian region, where Vietnam and Mongolia are located.
