BEIJING - Li Jiangong, the head of Bureau of Land and Resources in north China's Shanxi Province, is being investigated after being suspected of "severe disciplinary and law violations," said a statement published on the website of the CPC Central Commission for Discipline Inspection on Thursday.

The probe into Li is the latest in a string of investigations into Shanxi's high-ranking provincial leaders.

Shanxi is one of the major coal producers in China and contributes greatly to the country's energy supply.
