China media immediately began to mock Mr. Ma when Alibaba launched a mobile gaming platform, take revenue shares from third-party games, at the start of this year. Many mobile games, including US-made Dots, would be added onto it. Alibaba now also owns UC Web’s gaming business, since it has fully acquired the Chinese mobile browser and mobile service developer. Alibaba poached Liu Chunning, former senior exec at Tencent, to take charge of its mobile gaming business. When launching the mobile gaming platform in January, Mr. Liu said that Alibaba would take smaller a revenue share than Tencent.
