China and South Korea do $300 billion a year in trade. China roughly the same value worth of trade with Japan. They do maybe $5 billion a year in trade with North Korea.
I’ve heard they like having North Korea as a buffer, and they don’t want the ethnic Koreans in Northeast China getting riled up. But in the modern age, why is a land buffer with South Korea so important? Also, most of the ethnic koreans live in a small area in one province in China, so it isn’t like upset there would lead to mass unrest in China.
I’ve heard the arguments for what China gets out of its alliance with North Korea, and I don’t get it. North Korea is constantly threatening war, any true war by them would cost China trillions in economic activity because even if China isn’t hit, its 3 biggest trading partners (US, South Korea, Japan) would be attacked.
Also, why is a mass influx of North Korean immigrants so worrysome to them? What do they fear the migrants will do?
I suppose you can make the argument that China supports North Korea due to ideological similarities, but China and Vietnam have ideological similarities and their relations aren’t that great. Same with China and Laos, there are issues with the relations.
Also, if (possibly) the North Korean regime does eventually collapse, many people there are going to learn that China helped prop up a brutal, inept regime for years and this will likely create a lot of resentment among the North Koreans. Maybe, but maybe not. Stalin is still beloved in Russia 60 years after his death so who knows.
Supposedly China wants ‘no war, no instability, no nukes’. So what do they get out of supporting a regime that threatens war, causes instability, pursues nukes?
