The action is similar, but the purpose is entirely different.
Gambling is illegal in China, except for state-owned lotteries. But gambling using e-currency, such as Q-coin is legal, because it can be classified as online entertainment not involving "real" money.
If Q-coin/RMB exchange is permitted, then there's no difference between online entertainment and illegal gambling.
Online gambling is also illegal in US, same logic US should have banned Linden dollar and WOW gold also.
Also, Q-coin is not like Bitcoin at all. Q-coin is solely issued by Tencent, and its only purpose is to purchase Tencent value-added services for entertainment. It's more like casino chips rather than e-gold or Bitcoin.
Note that Tencent is a large corporation (largest in Chinese Internet industry) and it's likely to attract a lot of attention from the government.
On the other hand, Chinese government feels much more comfortable dealing with corporations and they are VERY scared of any unsanctioned grassroot movement, because they don't know how to deal with it, banning it is their first instinct.
Big corporations are usually participants in law-making too. Don't forget that it's in Tencent's interest to ban Q-coin/RMB exchange, because newbies will have to buy Q-coin from Tencent.
I can't believe any company would willingly give up the power of becoming a pseudo central bank and literally minting money on their own.
So, China has
- The most similar and compatible e-commerce system (escrow instead of chargeback)
I failed to see how this will make Chinese government more bitcoin-friendly. It may just as well give them excuse not needing to use bitcoin.
- The most established virtual currency industry and culture (over 98% adoption among netizens)
Virtual currency? without covertability, you meant online game token?
- The real need to unify currency with US (the CNY trade surplus is always pulling Chinese export economy back)
They don't want to use USD b/c US controls the issuance;
they don't want to use gold b/c they failed to accumulate enough of it;
they don't want to use bitcoin because its philosophy is total against their central-planning and totalitarian dogma.
What they really want is IMF (SDR), one world currency, and one world government.
