For years, it has been a common practice among wealthy Chinese to send large chunks of cash abroad and to secure foreign residency rights against the day when business or politics turns against them. For many, those days have now arrived. The US and other English speaking countries are their preferred destinations.
I would welcome them, but I'd be a bit leery that some of them could still be Chinese government agents.
I wonder how many of these fellows are in Singapore with different names, or Burma, or Vietnam. They can buy new identities in any part of mainland Southeast Asia.
