After a month with no one at the helm, China’s National Energy Administration finally has a new leader.

The job, China's top role in energy regulation, went to 54-year-old Zhang Jianhua on Wednesday. The position became vacant in late September when Uygur official Nur Bekri stepped down amid an anti-graft investigation.

Zhang, previously the general manager of PetroChina, is the first director of the National Energy Administration to have an energy background since the authority's formation in 2008. His four predecessors had little experience with the industry before they headed the energy regulator, and two of them were ousted for corruption scandals.
