Su Jinsheng, Chief Engineer of the Ministry of Industry and Information Technology (MIIT), is under investigation by the Central Commission for Discipline Inspection of the Communist Party of China, due to an alleged "serious violation of discipline."

The MIIT didn't give further details about Su's investigation, but it has been reported by the media it may be related to earlier investigations into a group corruption case inside state-owned China Mobile Limited, the world's largest mobile phone carrier in terms of the number of users.

Su, 56, became director of the telecommunications management bureau of MIIT in July 2008 and was assigned the post of chief engineer of MIIT in April 2009.
