The communist revolution in china led to a split of the korean government, after which, the north koreans, aided by the chinese, attempted to take south korea. what did this lead to?

The Chinese came later when South Korea aided by the United States pushed North Koreans aided by the Soviet Union out past the border near China's border. That's when the Chinese leader mao dezang(Idk how to spell it) told them to not get any closer. Chinese was already communist. So in theory it lead to a war that is still not officially over.

Very useful. it is to learn because history repeats itself so learning about it those mistakes not happen again.
