Logically, for China Google to sell your data to Chinese Buyer, then US Google must have sold your data to China Google. If it is illegal for US Google to sell data to third parties, then US Google could be sued for selling that data to China Google. However, since the USA is all about "Freedom meaning we can do what the fuck we like with your data", and not "Freedom from persecution", there's no reason that US Google couldn't do what you describe. If you were a European citizen, and it was German Google selling your data to China Google (or US Google), then that'd be a very different story. It seems odd that you're worried about China, when you live in a nation that has been proven to wiretap you by the government, and where private transactions are authorized based on information which three credit score companies store completely insecurely.
