Baidu Launches English Website for Developers
The English site, which at present is limited to introductory materials about Baidu's developer services, will eventually make it possible for developers who do not read Chinese to build apps for the Chinese market, tapping into Baidu's strengths in search, LBS and maps, cloud storage, and numerous self-developed technologies.
There isn't much documentation yet. Apparently that will be coming in a few months.
