The Chinese goverment granted Google the permission to open a official Chinese Google search engine.
Even without an official Chinese language site, Google was already doing rather well. The company had a 21.2 percent share of searches, not far behind market leading Baidu with a 36.3 percent share. Google last year bought a small portion of Baidu, although it is unclear if they will maintain that stake with the company now officially operating in China.
In the comming weeks several other companies plan to launch Chinese search engines. More details at BetaNews
