Kim Il Sung was really in the Soviet camp and i betcha they would have been secretly annoyed at the NK's for starting the war, as they had unfinished business with the KMT and Taiwan.
Things might have been so different if it hadn't been for the Korean war. Decades ago I remember reading accounts of senior American officers who were with Chiang during WW2 werent overly complimentary of him, so some of those observations might have influenced the politicians, and relations might have become more warmer with CCP, instead of nearly three lost decades.
I don't think the U.S.-China relation would be much warmer in the 50's and 60's even without Korean War because China was, after all, communist. And during that time, the West was pretty paranoid about ANY communist state.
One example: even in the 1979, when Taiwan was still an authoritarian state under marshal law, US still felt bad about abandoning the island and came up with the Taiwan relation act. Faced with dictatorship (Taiwan in 1979) and communism (China), US at the time still felt a dictator could be consider a friend (actually, I bet many in America still feel the same now).
