The rules that regulate retired government officials are likely to be tightened amid the country's enhanced anti-graft campaign, analysts said.

The Organization Department of the Communist Party of China Central Committee reiterated on Tuesday that retired officials may not violate Party rules by being employed as independent board members in companies.

All retired officials, including those who hold jobs at universities or NGOs, are prohibited from getting part-time jobs at companies, an official from the department told Xinhua News Agency.
