ROK Drop favorite Andrei Lankov has an opinion piece in the Korea Times that explains how China’s supposed harsh line with North Korea was merely a short term fluctuation and things are back to normal between the two countries:
For a brief while, South Korean diplomats were in a rather celebratory mood: it looked like China, for a change, had joined the ROK and the U.S. in their efforts to subject North Korea to the toughest sanctions ever. Indeed, in early March the Chinese representative in the U.N. Security Council voted for Resolution 2270 which introduced such measures, and for a while the united front looked like a reality.
Frankly, for yours truly, it was a surprise: the harsh position Beijing had seemingly committed itself to was unprecedented, and China’s switch happened quite suddenly. However, now it seems that this change was merely a short-term fluctuation.
There are many signs of a warming of relations between China and North Korea. In early June, Ri Su-yong, the former North Korean foreign minister who currently is the Korean Workers’ Party vice-chairman responsible for foreign relations, visited Beijing. It is the first time since 2013 that a North Korean official of such high rank has appeared in the Chinese capital. Among other things, Ri was granted an audience with President Xi Jinping. It lasted merely 20 minutes and therefore was, first and foremost, a formality, but it still had much symbolic meaning. It is equally important that the Chinese media devoted much space to describing the visit.
Simultaneously, the Chinese Foreign Ministry spokeswoman expressed dissatisfaction with the new U.S. policy initiative ― unilateral sanctions, targeting banks that deal with North Korea. On the other hand, the U.S. authorities subpoenaed Huawei, a massive Chinese telecommunication company, for its alleged deals with North Korea. There is also a growing body of evidence that China is not being as strict with sanctions’ enforcement as many had hoped for.
There is nothing surprising about all this. Like it or not, when it comes to the Korean Peninsula, Chinese interests are seriously different from those of the United States. [Korea Times]
You can read the rest at the link, but like I have always said China is never going to take a position that would risk the stability of the Kim regime. As bad as the regime is, to the Chinese government it is better than the alternative of regime collapse and the unification of the peninsula under South Korean rule backed with US troops.
