Culture has nothing to do with the fact that China doesn't want a bunch of US troops on their border, lol
And Beijing is apparently concerned with the prospect of a refugee crisis, despite your vote of confidence.
Quote:
China has regarded stability on the Korean Peninsula as its primary interest. Its support for North Korea ensures a buffer between China and the democratic South, which is home to around twenty-nine thousand U.S. troops and marines. “While the Chinese certainly would prefer that North Korea not have nuclear weapons, their greatest fear is regime collapse,” writes Jennifer Lind, a professor at Dartmouth University.
The specter of hundreds of thousands of North Korean refugees flooding into China has been a worry for Beijing. China’s promise to repatriate North Koreans escaping across the border has consistently triggered condemnation from human rights groups, and Beijing began constructing a barbed-wire fence more than a decade ago to prevent migrants from crossing. The majority of North Korean refugees first make their way to China before moving to other parts of Asia, including South Korea. However, tightened border controls under Kim Jong-un have decreased the outflow of refugees.
