This is not accurate. If you look back to the post:
https://bitcointalk.org/index.php?topic=229438.msg4007805#msg4007805 , Raphael clearly states that the deposit bank account is in Pudong (which is the financial district in Shanghai). BTC China ALSO is HQ'd in Pudong, so I don't understand why Raphael thinks he is exempt while BTC China is not???
tldr - do not deposit in Bitfinex until this is cleared up.
Did you consider reading the post you linked to? It answers your question. They are unaffected by Chinese regulations.
