When the US sanctioned Russia by blocking their use of the SWIFT system, China offered their alternative. As more countries come off the dollar standard, the value of Chinese holdings will go up: an investment opportunity!
The problem for foreigners trying to invest in China is that you can never really own something there. Chinese businessmen will accept the money, but a piece of paper saying “a foreigner owns this” isn’t enforceable in a dispute.
The US needs to be on this same footing with China. Why should the US give China a stronger claim to land surrounding our military bases than they would allow US citizens to have to a remote rice paddy?
