I don't care about this kind of stuff as much as a lot of people do. Hopefully they also start blocking China from buying up USA farmland and housing.
A proposal to stop the purchase of property by nameless numbered entities ("123 LLC") would have my full support. It's not like foreign buyers put down "China Inc" on the purchase forms.
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.
