There's one more thing we can do, and that is to practice the simple approach or reciprocity. We can't buy property in your country? Fine, you can't do it in ours. You want concessions to build factories? Fine, we want the same. You want your citizens to enjoy the freedoms of our country? Fine, we want our citizens to enjoy those same freedoms in your country. Oh, you would rather not? OK, then we'll treat your citizens in our country like you treat them in your country. How's that? We can track them, search their homes for no reason, imprison them for no reason...

Reciprocity. Why the hell countries don't do this is beyond me.

That's something that has bugged me as well. Chinese can (and do) go to Australia and buy cattle-farms the size of a small US state. But try doing that, as a foreigner, in China. Was once called a racist for arguing this point on a forum, but it's a clear case of the scales tipped in favour of a totalitarian country. Why are we doing that?
