That's an incredibly bad idea, you are exposing yourself to a lot more risk, than using a western cloud.

They are not in contact with our authorities, until they decide they want to. It's not like you are a Chinese factory owner making counterfeit wranglers, I doubt they would deny any kind of request from a western government about a westerner.

Your access to the service is also under risk, at any time there could be a breakdown of relations leaving you unable to pay for the service, that would have happened already, if you had chosen Russia instead of China.

Your behavior also looks suspicious to the western intelligence apparatus. Sending potentially terabytes to Chinese servers as a private individual may very well put you on their radar.

As others have noted you are setting yourself up as a prime candidate for an intelligence asset, they could at any point blackmail you to perform any action they want.

With what would they blackmail you? The terrabytes of CSAM they could at any point plant in your account. Do you think they would be above doing that, if they had anything to gain and were aware that you exist? Or do you think your Chinese provider would require a court order to give you up? Your entire bet is that they don't know that you exist.

My main point as advice to others mostly is you shouldn't put your self in the hands of your adversary.

I don't even know how you trust their software to run on your system.

PS: If you think all these are farfetched and paranoid, I will remind you that China routinely takes hostages to achieve diplomatic concessions https://en.wikipedia.org/wiki/Hostage_diplomacy#China
