South Korean, Chinese leaders set agenda for June meeting in Beijing SEOUL, May 30 (UPI) -- Denuclearization may be at the top of the agenda when South Korean and Chinese leaders meet in Beijing in late June, a South Korean official said. A diplomatic source in Seoul was cited by the Yonhap news agency as saying North Korean nuclear issues would be an important part of any declaration coming out of next month's meetings in Beijing. South President Park Geun-hye is to visit Chinese President Xi Jinping in Beijing in late June. Xi is also to meet with U.S. President Barack Obama next week in California. "There is a high possibility that the word denuclearization will be included in the joint declaration in regard to solving the nuclear issue of North Korea," the source said. A delegation from North Korea visited Beijing last week to meet with Communist Party leaders. It was the first such visit since Kim Jong Un took power in North Korea in 2011. Yonhap reports that North Korean leaders said they may be willing to resume multiparty nuclear negotiations. Talks between the Koreas, China, Japan, Russia and the United States were suspended in 2008. North Korea has since conducted a series of nuclear tests. Tensions on the Korean Peninsula were elevated early this year but eased at the conclusion of joint military drills involving U.S. and South Korean forces.
