The world's largest Internet search-engine provider has bought a stake in a Chinese file-sharing service.
U.S.-based Google and China's Xunlei Network Technology company announced the strategic partnership in Beijing Friday. They did not reveal any details of how they will work together in the world's second-largest Internet market.
Xunlei offers music and video file-sharing services. It claims more than 120 million users. Google, which recently bought online video-sharing company YouTube, has sought to expand its presence in the online video market.
Separately, Google announced it has formed a partnership with China Mobile, that nation's largest telecommunications carrier. The partnership will provide online search services for mobile phones.
The new deals reflect Google's strategy of broadening its global Internet presence.
Since entering the market, Google has lagged far behind China's top Internet search-engine provider, Baidu.com.
The Chinese government tightly regulates Internet content.
Last year, human rights groups criticized Google and other U.S. Internet companies for cooperating with China to censor the Internet.
