Mao Zedong led the Communist forces to victory in China's civil war in 1949, establishing communist rule. His leadership brought major changes like collectivization of farms and the disastrous Great Leap Forward and Cultural Revolution programs. Communism also spread to North Korea, with the country dividing after WWII and Kim Il Sung establishing a communist dictatorship in the North. This led to the Korean War as the North invaded the South in 1950, which ended in a stalemate but firmly established communist rule in North Korea and capitalist influences in the recovering South Korea. Overall, communist victory in China and North Korea's division increased tensions between the US and Soviet-backed states in East Asia during the Cold War.
