China will soon begin another round of Communist Party disciplinary inspections — the third since the party re-elected its leadership in 2017.

The inspections will look into three central government departments and 42 state-owned enterprises (SOEs) under the central government, according to state-run Xinhua News Agency.

Targets include the State-owned Assets Supervision and Administration Commission, the National Energy Administration, and the State Administration of Science, Technology and Industry for National Defense. The SOEs range from telecom and aerospace technology to investment firms.

Zhao Leji, secretary of the Party’s corruption watchdog — the Central Commission for Discipline Inspection — and head of the inspection round, said the SOEs must improve “political awareness” and strengthen related supervision to better implement Beijing’s mandates.

According to People’s Daily, the inspection round will be carried out by 15 inspection work groups. 

Disciplinary inspections have long been a crucial part of the Party’s anti-corruption campaign, looking into suspicious cases and requiring government departments and SOEs to respond to inspection feedback with actions. This very often leads to exposure of corruption cases which could put high-level officials under harsh punishment.

During the first inspection round last year, the National Bureau of Statistics further investigated into 131 fixed income investment projects, and removed three bureau officials from their positions, to respond to the inspection group’s criticism. Eastern China’s Shandong province punished 3,095 Party members for the same inspection round.
