The Chinese government denied on Tuesday the legitimacy of a Kyodo News report alleging that a military source leaked the details of a Chinese contingency plan for the collapse of North Korea.

The Japanese outlet said the document in question was written by members of China’s People’s Liberation Army (PLA) and included plans that established protocols for the screening of refugees and allusions to foreign hostile forces. It also allegedly included a plan to detain North Korean leaders in Chinese camps for monitoring, protection and to prevent them from making decisions counter to Chinese national interests.
