In Asia, it is usual to separate data transfer rate and data transfer allotments between domestic and international bandwidth. Note some Asian countries have great national backbone infrastructure with providers offering plenty of high quality low cost domestic bandwidth. However, international bandwidth is an issue anywhere in Asia Pacific (and Oceania, and Africa ...), as it costs a lot and is slow and low quality, usually shared -- don't expect a cheap dedicated server or VPS having more than 1-2Mbps shared international bandwidth in that regions.
Also should be noted in Asia peering is not that common between network operators, as many times you have close geographic proximity but not network proximity and it is not unusual networks from neighboring countries peering only in the US or Europe.
Regarding China, do you have the needed licenses for China (ICP, and additional for other services than HTTP)? China requires a government license to people/companies operate sites, blogs, forums, ... issued only to people/companies living/operating in mainland China.
