PRC gained admission because US pulled the diplomatic weight behind PRC as part of the Nixon's changed policies. Otherwise, it would not have been possible as I said in 1971, China was diplomatically isolated with Sino-Soviet split.
Again for the British empire, though two different races of people involved, should it matter when talking about majority?
The civil war post ww2 happened between 1946 to 1950.
1. KMT was supported by US and US airlifted KMT to major cities in the north to prevent the CCP from taking over the cities while they were strong in the villages as they had promised the land reforms. The crucial one here is the US support.
2. USSR was holding on to Manchuria until CCP took over. If USSR had moved away from Manchuria, KMT would have taken over and the resources in Manchuria would have helped KMT.
3. USSR provided CCP with the captured Japanese arms in tons. This played a crucial role
Do you think with the above 3 factors, with just the farmers and no support from USSR, CCP would have won the civil war?
Granted my understanding is that USSR removed the industrial machinery from Manchuria as payback for the support. But beyond that I did not find anywhere that Mao payed back USSR for the support during the civil war as I mentioned before.
Again the topic about the Great leap forward, it started in 1949 and more or less ended in 1957/1958.
The Korean war again happened between 1950-1953 where China was a major player.
Considering that China was heavily involved in a war against US, imagine the resources it would have spent. So in my opinion, the Great Leap Forward failed due to the Chinese involvement in the Korean war. Why China wanted to be a player when they were struggling to get up and running as a nation with the civil war just ended? Isn't it pointless in blaming USSR?
Again I could find 1 link
The Causes of the Victory of the Chinese Communist Party
They have indicated Soviet aid (mind it - not loan) as a crucial piece.
