I don't think China's foreign reserves are likely to be seized, as they are mostly held in safe and liquid assets, such as US Treasury bonds.
I can't find anything definitive. But I expect that's exactly what the Russian foreign reserves were invested in. (Central banks are all pretty conservative and copy each other.)
I personally wouldn't like to predict how safe these assets would be if a war breaks out and the US congress starts passing legislation.
If I were China, I wouldn't take that risk for 1%(?) interest income that these legacy bonds are paying. Now would be a good time to take profits as US bonds have just rallied on mere expectations that rates will be cut in future.
