China-based online game developer Giant Interactive Group (GA) is now on the hunt for a new chief executive following the resignation of Yuzhu Shi. He will step down on April 19 and will stay on as the chairman of the board of directors.

The firm said it would formally announce his successor as CEO on that date.

In the press release announcing the move, Giant Interactive did not provide the reasons for Shi's resignation. It quoted him as saying that he would "continue to oversee the Company's strategic direction" in his role as chairman.

Shi has been with Giant Interactive since its founding in 2004.
