For you CCP not going control of Manchuria until years after Soviet withdrawal is another matter yet you still claim it was given to CCP by USSR
The USSR gave Manchuria to the CCP and then during the CCW the KMT conquered parts of Manchuria, the fact that they lost parts of it doesn't mean the USSR didn't give it to the CCP, saying that is arguing against reality.
What TL are you talking about ? OTL France gave up Indochina to Japan and that won't be it's territory unless Japan returned to it. That decision can only be made by US
You are arguing against reality, France never gave up on the colony, the concessions that the French gave to the Japanese never included giving up on the colony they only gave things such as using some Indochinese ports and stationing some troops. For most of the war the French colonial institutions remained in place, until the Japanese couped the French on the 9th of March 1945.
The Japanese control over Indochina was taken by the French in a few months, the US doesn't have any mediating influence and it doesn't want to, they have no reason to force the French to give up on their colony.
Again what TL are you talking about OTL US didn't care about how many angry France can get when it asked China to take Indochina. It's the other way around France had to placate America because it was toed economically .
In what TL did the US ask China to take over Indochina?
Even if it did Chiang doesn't want and cannot take over Indochina, France failed to do so after more than 100k casualties and with US support, China will never be able to conquer and hold Indochina and even assuming some divine intervention allows you to do so you gained a rebellious territory which ,objectively, isn't worth that much.
Stalin doesn't matter because he will be dead by 1953 and replaced by Khrushchev eager to support even non communist state against the west
Not really since it is also a right-wing dictatorship who hates communism and even if he wanted to he cannot do much about the fact that China is going to be destroyed by the technological superiority of the West, not to talk about the fact that he already has problems at home.
Had Franco invaded France in 1956 would've the USSR supported him? Same thing here.
US won't care even if Western colonies go up in flames as in the First Vietnam War
The US invaded countries in the Americas because someone touched their business of selling bananas, now imagine how it will react to a country that is actively invading its allies
What's the point of NATO if you support those who invade your allies?
If you think Guangzhouwan, Hong Kong and Macau were in only concessions in China they you know very little about concessions in China
These are the concessions returned to China before Guangzhouwan
Shanghai international settlement
Beijing legation quarter
Kulangsu International Settlement
British concession of Shamian Island, Guangzhou
That's not the point, 1 and 3 were returned in 1943, 2 wasn't a concession and 4 was returned in 1945. But GB, Portugal and France won't give anything to China if it starts invading French colonies.
OTL US also feared China would be in the Soviet sphere
You cannot support China while it is invading someone else's territory especially not when they are your allies.
And if Chiang starts to do this then he would be (rightfully) considered an enemy of the West, he may or may not join the Soviets but he is already your enemy.
Even here France and GB will be on the 'wrong' side of the conflict and don't have any rights to defend themselves,
Yes they do, HK, Macau and Guangzhouwan are internationally recognized as European territories and China (under the Qing) has acknowledged them, meaning that they are their territories and that you are invading them, it's not the same as invading Egypt because it nationalized the Suez canal.
What do you know Suez crisis ? Sues canal was British territory as much as Hong Kong yet USSR and US forced it to withdraw from there
You are arguing against reality, Suez was in Egyptian territory, the only thing GB and France had was the shares of the Suez company which had the canal but it's not because a Brit bought a house in Egypt that it becomes part of Britain.
