this is not a issue with Chinese buyers, this is a issue with existing land owner, who would do everything to imcrease sell price. Don't say somehow it's the buyers fault. Foreign buyers don't vote in election. it's the vote and money of property owners that allowed those purchase of land with no real purpose other than investment.
My post didn't blame them entirely. They have funds they need to get out of China so they buy property abroad. Having a child who is studying abroad is one of those ways. There's little intention to actually live there, let alone integrate with the community.
The big question is how those funds were obtained. How can locals compete with buyers who can essentially print money? Funny money. Chinese banks are unauditable.
Your last paragraph can't be serious. Are you suggesting somehow China can print dollars? US lands are of course bought with US dollar, which reasonably assumed, only the Fed can print.
