Don has a good TL where the war starts with a pre-emptive Soviet strike on Harbin and Lop Nur. The PLA fights with fanaticism and nuclear mines crush the Soviet strike force. Nixon then secretly sends military aid to China in exchange for China ending assistance for North Vietnam. Anti-Soviet riots break out in Warsaw, Prague, and Budapest. India and Pakistan are again at war.
All in all not a fun scenario for anyone.
The advantage the Soviets had in airpower, armor, and technology in general would be largely negated by China's overwhelming numbers
Russia might go after the dams of the Yangtze and other rivers to hurt the Chinese energy grid.
I don't think those dams existed yet...
Yes, the Soviets will roll over China rather easily. There will be some nuclear warfare, it will get ugly. But China won't last long conventionally.China in 1969 was a DPRK-esque basket case and this carried over to the PLA. By contrast the Soviet Army was one of the best in the world and had plenty of experience in blitzkriegs, one in Manchuria itself no less. The Soviets would've entered and taken Manchuria and Inner Mongolia much in the same way they did in 1945 - in tanks, in planes, and rather quickly. The Chinese nuclear force would have been bombed into the ground preemptively. Surviving bombers trying to get to Moscow or anywhere else have only slim chances of making the trip, and even if they do, the result is the veritable end of Chinese civilization. Nuclear landmines are still ultimately just landmines and won't stop the Russians from attaining their operational goals, which would likely consist in a march to Beijing, kicking out Mao, setting up a nominally friendly government with authority over Northern China and Manchuria with some diplomatic concessions attached, then leaving.
Seeing the royal mess Mao has made of the country and the party, it wouldn't be hard to find collaborators. The Soviet enemy isn't about to go full Nanjing on the Chinese population either. Basically there is enough potential resistance to Mao that a new government could be set up and be given effective authority relatively quickly. This PoD is one of those "I'd love to write it but it'd take a lot of research and effort I'm not prepared to sink into it" projects.
Oh, on paper they'll be looking fine. But mission creep has a habit of setting in, and given that this was a period where Brezhnev and Kosygin were both trying to consolidate power unto themselves, neither Politburo faction is going to want to look weak to the other. The geopolitical sense of leaving Southern China to Maoist rot will be undermined by the Soviet desire for hegemony and power politics in the Kremlin, IMO.I think the Soviets would be able to avoid the Afghanistan-esque trap, but only if they deign to mostly remove themselves from internal Chinese (i.e. new govt., not wherever Mao or his followers decide to set up camp after getting curbstomped) political affairs after the war. This could be a tall order as the Soviets liked to control other countries, especially those that had previously made trouble for them. China is one of these countries. However, assuming a "Soviet China" existing roughly north of the Yellow River with the rest either in chaos or under the tenuous control of Maoists, I think it could be successful even as a nation in the Soviet orbit, in the same way that East Germany wasn't a complete basket case. Certainly a North China run along the Soviet idea of socialism would do better and be more stable than Mao's "TAKE ALL UR POTS AND PANS AND MELT THEM DOWN" lunacy. Manchuria is already gifted with natural resources and industry, while Beijing provides an existing political center for administrative needs.
The USSR bleeding itself dry trying to subdue China will leave North Vietnam high and dry. What's to stop Nixon from ordering a push all the way to the Chinese border knowing the Chinese aren't in a position to repeat the Korean intervention?
And then what's to stop the Taiwan lobby from demanding US intervention into southern China to grant Chiang a foothold back on the mainland?
There would be three Chinas: a Soviet puppet north, a disintegrating Yangtze River Valley, and a not-so-willing US puppet south. And the Soviet puppet government will still face guerrilla warfare despite Mao's insanity: look at the Cambodian guerrilla war against the Vietnamese-backed puppet government.
Trying to imagine the propaganda by each side.
You're the Capitalists lackeys!
No You're pawns of the Bourgeoisie!
You're the revisionist scum!
No You're the revisionist traitors to the revolution!
Are too!
Am not!
Are too!....

Methink this is a version of an old legend told about Mao and Stalin. Mao proposed to provoke WWIII and said that even 1:5 loss ratio would mean that West is exterminated and Commies are victorious.As of '79, the Chinese planned to launch a first strike on Moscow. They knew they would suffer the worse of a nuclear exchange but between superior numbers and a decapitation strike, they figured they would be able to hold out and eventually overwhelm the Soviets. Apparently Deng told Carter this who was somewhat horrified about their rather flippant views about the deaths of millions of people in nuclear war.
