China is one of the biggest games market, including mainland China, Hong Kong, Taiwan,
FORZA6 is a very perfect racing game, but his biggest component,
Painting shop, in mainland China can’t access, can’t read the other player’s painting, this is a great tragedy.
I hope you can solve this problem as soon as possible
I just left Shanghai after 3 years. So yeah, I know that the situation with Forza is simply HORRIBLE.
I had a 50M China Telecom fiber optic connection + VIP international traffic priority, open NAT etc…but I still couldn’t find liveries and couldn’t play online most of the time.
I could be wrong here, but I think it has something to do with the Chinese government not wanting you guys to see it, like they might have said to Turn 10 “you can bring your game here, but no storefront” or whatever, again I could be wrong, but it does seem very plausible this is why you can’t access it. The Chinese governmentis very sensitive with this stuff.
The “great firewall” of China is most likely blocking content because you know, the government knows what’s best for you. Speculation of course, though most likely.
That’s CHINA Problems ONLY
No one can fix that
Luckily no problem in Hong Kong 
There is a strong censorship policy in mainland China. Many topics are forbidden from sharing on the Internet, and thousands of popular websites are banned. Designs shared could feature a topic that is censored in China, especially those that are against the Chinese government. No way to bypass that, I’m afraid.
