I hope you understand that North Korea is China's backyard dog. China must be desperate now, so trying to stir shit through its dog.
Those who still remember Fatty Kim's brief visit to Sinkieland... he had to ride on a train through the China mainland. He didn't fly here.
China is the constant and diligent shit stirrer, doesn't matter if it's Taiwan, South China Sea, mountain border with India, the Middle East, Cuba etc.
