No, it isn't about people being more prone to buy property in one place, rather than another. Let x be a any number in [0, infty), I literally can not buy property in China for any x.
> The answer is yes, foreigners are allowed to purchase property in China! The essential requirement is that you have studied or worked in China for at least one year on a residence permit. Foreigners are allowed to only own one residential property for dwelling purposes. You may not rent out the property or act as a landlord. Requirements and restrictions may differ in different provinces and cities. For example, Shanghai requires that non-Shanghai hukou families, including foreigners, have to provide proof of income tax or social insurance to the local government.
You can not actually buy property in China, you can only lease it for a number of years, and it will always be held by the government of China (you can easily search this on the web). And after some number of years, it'll go back to them, and you'll have nothing.
Simply because when XXX nationals come with all cash offers and willing to pay above market & waive all contingencies, sellers are willing to sell.
It just so happens that certain nationals are more prone to having that sort of money than others.
