Giant Interactive Group (GA) has quickly replaced its chief executive. One week after announcing the resignation of Yuzhu Su, the company revealed that its board has tapped Wei Liu as its new CEO.

Liu will take up her new position on April 19. She had previously served as the firm's president; she will be replaced in that capacity by Xuefeng Ji, who, at present, is Giant Interactive's senior vice president of research and development.

In the press release announcing the move, Liu provided a strong indication of how the company will proceed under her leadership. She was quoted as saying that, "beginning in 2013, mobile games have become our new strategic focus, and we will build on this new business through internal development and M&As."
