Zheng Baigang, deputy director of the Ministry's supervision department, said at a regular press conference that some international organizations failed to have a comprehensive and correct understanding on how Chinese policemen operate.

Materials released by the Ministry of Public Security on Tuesday show that China's police supervision organs have made great efforts to regulate the police.

In 2002 and 2004, the Ministry issued two regulations to provide grassroots police with guidelines on detaining and interrogating suspects.

Since 1997, police supervisory bodies have extended their supervisory work to grassroots police stations to further prevent citizens from police abuse.

In 2005, China's police supervisory bodies found and redressed 12,000 cases of inappropriate police enforcement and withdrew or corrected another 136 cases. Enditem
