Outside of its mobile browser, UCWeb has already partnered with Alibaba to release a mobile search engine in China called Shenma. Launched in April, the product now has a market share of over 20 percent, according to the company.
The merger will give UCWeb more resources, and also access to Alibaba's partnerships with Sina Weibo, a leading social networking site, and Youku Tudou, a top video site in the country, Yu said.
He added that he wants Shenma to reach 200 million users by the end of the year. Yu also hopes it can eventually become a global search engine. Alibaba will continue using the UCWeb brands.
