China will not allow chaos and war to break out on the Korean peninsula, which would be to no one's advantage, Chinese President Xi Jinping told a group of Asian foreign ministers on Thursday.
North Korea's drive to develop a nuclear weapons capability, in defiance of U.N. resolutions, has angered China and raised tension in the region.
"As a close neighbor of the peninsula, we will absolutely not permit war or chaos on the peninsula. This situation would not benefit anyone," Xi said in a speech to a Conference on Interaction and Confidence Building Measures in Asia.
North Korea conducted its fourth nuclear test in January and followed that with tests of various missiles that could deliver such a weapon.
The isolated state is expected to conduct another nuclear test before a rare congress of its ruling party, beginning on May 6, at which young leader Kim Jong Un is expected to try to cement his leadership.
