Is that where it went? How do we know? Whether the business dealings are dubious or not, don't rich business people make (and move around) lots of money?
It would concern me a great deal. Did the Chinese government put it there? Or was it simply money earned by doing some kind of business there?
Was there a gift? I mean, money going into and out of a business account or a rich business man's account is not unusual or unexpected. If we know more about that money, and it's not benign business dealings, prosecute the fat orange f*cker.
