BEIJING, May 5 -- The People's Liberation Army (PLA) of China has made progress in clearing out illicit apartments and vehicles, but the anti-corruption drive will continue, a PLA statement said Monday.

The PLA sent out 18 inspection teams to the general departments of staff, politics, logistics and armament as well as military area commands at the end of last year, and undesirable behaviors uncovered during the inspection have recently been reported, the statement said.

The inspection also targeted overuse of secretaries and office attendants for senior military officers and living standards of retired senior officers and their families.

While some achievements have been made to correct corrupt behaviors, they are still far from expectations, the statement said.

PLA units are urged to make corrections and regular inspections will be conducted strictly.

Authorities will enhance probes into corruption, such as spending public funds on feasts and travel, using public vehicles for private purposes, presenting gifts during holidays, and holding extravagant wedding ceremonies and funerals.

These behaviors must be prevented from returning, the statement said.

The PLA started an anti-graft campaign last year to echo the Communist Party of China's drive to clean up undesirable work styles such as formalism, bureaucracy, hedonism and extravagance.
