I m using this as a source : https://youtu.be/L3E1feh30fE?t=59 , and i m certain they want to ensure that their mobile titles do well in the chinese market (like their up-coming COD titles, as well as existing titles like candy crush etc). This requires that the chinese gov't "approve" them. They don't want to jeopardize this relationship.
