BEIJING (Reuters) - 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.
