Japan’s largest social-game website operator DeNA Co has partnered with Taiwanese chip designer MediaTek Inc to promote its mobile social games.

DeNA China will optimise its gaming products based on the features of MediaTek’s mobile chips and will offer its flagship mobile social gaming platform Mobage as a pre-installed application on phones using MediaTek Chips.

According to a company statement, DeNA’s Japanese-language Mobage service has almost 50 million users in Japan, and its Chinese-language version has more than 20 million users in China, Hong Kong, Macau and Taiwan.

The timing couldn’t be better as the Taipei Times reported a surge in MediaTek shares earlier this week to their highest level amid investor optimism that the company would become the world’s second-biggest chip supplier for 4G mobile phones.  Its mobile phone customers include Lenovo Group, Coolpad and Huawei Technologies.
