Please explain how China gaining Russian territory is so much worse than Russia having it.

Because China is a significantly bigger threat to the US than Russia. China is an economic giant.  Russias economy is weak.  The last thing the US or the world needs is China expanding. Add that Russians probable response would be nuclear and it’s a nightmare anyway you slice it.

True. On top of that, it would give China's Navy Vlad and Petr. Their submarines would replace the Russian ones in Petr, making the North Pacific a contested zone against a Navy that is larger than ours and is rapidly expanding. The Russian Pacific Fleet is nothing by comparison. It would also put China in a position to directly threaten the SLOC to Japan and Korea. Not to mention it would give them enough energy resources to survive a blockade of middle eastern energy sources. It would also put China on the Canadian and US border. It would make defending against the Chinese assertion of sovereignty in the South China Sea (and the 9 dash line) even more risky that it already was. Russia doesn't have such ambitions or any ability to exercise such military force in the Far East. Other than that, it is just fine.
