Japanese mobile social gaming firm DeNA will seek to expand by buying more game developers, its new chief executive, Isao Moriyasu, said in an interview on Monday.

In a bid to take its highly profitable business model global, the company is set to launch a global Android version of Mobage, its successful social networking platform, this month. A separate version for China will also be launched in July or August, Moriyasu said.

DeNA is also in tie-up talks with overseas mobile carriers on mobile game services, after agreeing to a deal with Japan's top carrier, NTT DoCoMo, that makes it easier for phone users to access and pay for DeNA content.
