South Korea’s ambassador to Japan said "high-level” talks are under way for a three-nation summit with China poised to happen this year, and it wouldn’t affect ties with the United States.

Those discussions are going well, Yun Duk-min, Seoul’s envoy to Japan said in an interview. There may be a "Camp David effect” that prompted China to reach out to its neighbors, Yun said, adding that a summit with Beijing wouldn’t hurt relations with Washington after the historic meeting with the U.S.

The foreign minister from South Korea and Japan met on the sidelines of the United Nations General Assembly to help advance a three-way summit and senior officials from the three Asian nations are set to meet in Seoul on Tuesday. Chinese President Xi Jinping and South Korean Prime Minister Han Duck-soo are likely to meet on the sidelines of a sporting event this weekend, Yonhap News reported.
