China will be closing North Korean companies operating in its territory as early as January next year as Beijing begins implementing United Nations sanctions against Pyongyang.
Joint Chinese and North Korean ventures will also be forced to close.
China, Pyongyang’s only major ally, has already banned textile trade and limited oil exports.
The move is part of an international response to North Korea’s sixth and most powerful nuclear test.
According to the spokesman China’s Ministry of Commerce Beijing has given a buffer period for implementation of the ban on coal and seafood imports from North Korea.
