[Pyramids]

Hong Kong or Singapore are much better choices, especially if you only need to host static files, as you avoid the legal requirements of having an ICP license. If you decided on a chinese provider anyway, be aware that almost all providers either block port 80 or filter unlicensed HTTP traffic (by deep packet inspection and automatic lookups against the sent "Host:" header.)

Keep in mind, latency in China is often high to begin with, so don't expect the same results as you'd get in most countries. For example, here is a trace from Beijing (Telecom+Unicom Route Optimized) to 36Cloud:

Another option to consider if you need an SLA or have concerns regarding availability would be Internap's Public Cloud in Singapore (Very good peering and availability, uses Internap's FCP dynamic routing technique. You can expect less than 100ms from almost anywhere in mainland China, while not compromising routing to everywhere else.)

Ping from Beijing (same network as above) to Internap Singapore:
