If my memory serves the people who handled the licencing in China for Ao and YS7 is another agency that is different from the TITS trilogy since the old one ran out of business since Falcom's departure from PC
There were a lot of shady practices too. They took the fan translation of FC and used it as the official release in China and sent legal warnings to the people who actually translated the game. SC's translation was a mess because of unicode problems, grammartical and diction mistakes, also SecuROM. The 3rd had censorship and SecuROM. Though all of the problems were remedied due to the power of the Chinese fan base.
Falcom is pretty popular in the Chinese speaking countries back in the days. YS6, OiF, Origins, Xanadu Next next all had proper releases.
