Japanese, Chinese and South Korean leaders agreed Tuesday to strengthen trilateral coordination to achieve the denuclearization of North Korea, with Pyongyang stepping up provocative rhetoric against the United States and their nuclear talks remaining at a standstill.

China, the chair of this year’s trilateral gathering, hopes issues on the Korean Peninsula will be resolved “through dialogue,” said the country’s premier, Li Keqiang, at a joint press conference following his summit with his Japanese and South Korean counterparts.

Prime Minister Shinzo Abe said it was important to "keep up the momentum" of talks between the United States and North Korea, adding that U.N. Security Council resolutions against Pyongyang should be "fully" implemented.
