VPNPro doesn't list ExpressVPN as having Chinese ownership. Wikipedia[1] claims it operates in the British Virgin Islands, and Quora claims the same. That written, a comment on Quora claims that it's owned by the CIA. Ha ha!
You don't need to be based in BVI to be registered as a business there.
(Weather or not they are owned by CCP or anything like that I have no idea, I'm just saying that being registered in BVI doesn't mean it's not possible for them to be owned by a CCP or anyone else)
The company in the British Virgin Islands is a shell company with HK ownership, AFAIK.
With the CCP taking over HK, ExpressVPN could be used to gather information on domestic dissidents and foreign visa holders. Assuming it's not already.
