Tencent, China's No.1 online game operator and its largest instant messaging provider, had bought Comsenz, a Beijing-based social-networking provider, Comsenz said in a statement on its website. Comsenz is backed by Google Inc, Sequoia Capital and Morningside Ventures.
The deal was reportedly worth more than $60 million, the newspaper said, quoting a source familiar with the situation.
Tencent could not be reached for comment.
Tencent, which bought a 10 percent stake in Russian Facebook investor Digital Sky Technologies (DST) for $300 million earlier this year, could be on the look out for more acquisitions as it seeks to expand its dominance beyond China.
