Under the agreement, Baidu's wireless search service will be embedded in China Unicom's 3G mobile phone modules. China Unicom's mobile subscribers will be able to use preinstalled applications to access Baidu products including web search, Baidu Knows, Baidu Post Bar, image search, news search, MP3 search and other useful services. Baidu (Nasdaq:BIDU)will also provide search functions within China Unicom's wireless Internet sites to service the carrier's users.

"We are very excited to join hands with China Unicom (NYSE:CHU) today following our partnership agreement with China Telecom (NYSE:CHA) in May," said Xuyang Ren, Baidu's Vice President of Marketing and Business Development. "As the leader in Chinese language search, we hope that Baidu's cooperation with major telecom providers in China will accelerate the development of 3G services and allow us to provide the rapidly growing population of mobile search users better access to information."

This can be seen as a major coup for Baidu, as it has once again managed to pip it's major competitor Google at the post. For China Unicom this is also a boon, with the upcoming launch of Apple's iPhone on their 3G network.
