I have been trying to stream video to China, but have encountered a great deal of problems. I have tested videos ranging from 550kbps to 400kbps. My servers are in the US. I have confirmed bandwidth of almost 50Mbps downstream speed from the server to somewhere in US, and over 450kbps in China. The videos are choppy. I am using RTMP with a Flash player on my website. Any advice would be greatly appreciated.
Choppy playback is usually caused by the video bitrate being too high for the client network capacity. You can look at the actual bandwidth by running the BWCheck example from the same server (see the examples folder where Wowza is installed). This tells you the bandwidth from that server to a particular client and is the only measure that is relevant.
But the great distance between server and client in your case, which is unusual, could be a problem.

I can tell you that unless you place a server in china, otherwise, nearly no hope to get a smooth video stream.

cychow is correct.
Streaming to China has a whole set of unique issues.
Not the least of which is packet inspection of incoming overseas traffic at the ISP level.
You really do need to get local boxes installed.
