Qihoo and Google

Qihoo 360 confirmed cooperation with Google China, ZDNet reported Friday, a move the report said may threaten China's current leading search engine Baidu.

Qihoo did not confirm the report when contacted by the Global Times Saturday, but revealed that the company is commercializing its search engine with the help of a third party that it would not name.

According to the ZDNet report, Qihoo's tie-up with Google is likely to begin early in 2013, and Qihoo CEO Zhou Hongyi has said that he was open to cooperate with other counterparts such as Microsoft and Sogou.
