You can just say that Chinese nationals without residency in the US can’t own land. Canada did something similar for foreigners and the legal defensibility of it seemed pretty good based on lawyers talking about it.

Basically, you can say (in legalese) that X group can’t be the controller of the land. They can open trusts or LLCs or whatever… but it’s transitive so their trust can’t name them as the beneficiaries and their LLCs can’t honor them as shareholders.
