At the news conference after the summit, Trump said that his top aides would meet with DPRK officials next week for further nuclear talks. The immediate follow-up discussions could add substance to a joint statement that some critics said lacks specifics. Trump also said he wants China's involvement in the signing of a peace treaty to replace the current armistice agreement after the 1950-53 Korean War. The annual US-ROK military drills are carried out twice in spring and fall. The springtime joint military drills were delayed and conducted in April to help create a favorable atmosphere for the Winter Olympics hosted by the ROK in February, to which the DPRK sent a delegation.
