Trump was getting ready to punish China for the CCPlague in his second term. What the punishment would have entailed, only Trump knew. That was all the more reason for China to work with Dominion and not let it happen.
That seems to be the obvious explanation of what happened. Plus we have seen cooperation by those paid off by China - such as the Gov and Sec State of Georgia.
China backed a coup with $$$ and leverage (e.g. Eric Swallwell) and none dare tell the truth - none dare call it treason.
