BEIJING, Feb. 17 -- China's People's Liberation Army (PLA) is mulling to revamp its official evaluation system amid a widening anti-corruption campaign in the country.

According to a document issued by the PLA General Political Department with the authorization of Chinese President Xi Jinping and the Central Military Commission (CMC), evaluations of army officials should focus on their political reliability, competence, clean conduct and trustworthiness.

Xi is also chairman of the CMC.

Those in charge of official evaluations should first seek advice from the Communist Party of China (CPC) committees at all levels, the document said.

They must also consult disciplinary organs to check whether the officials are honest and self-disciplined, it said, adding that results of the evaluations would serve as an important reference for official selections and appointments.
