XINING, Aug. 16 (Xinhua) -- A senior anti-corruption official of the Communist Party of China (CPC) Monday urged strict supervision and inspection of relief and reconstruction work in Zhouqu County, which was devastated by a massive mudslide on Aug. 8.

A supervision and inspection system must be established to ensure thorough implementation of the central authorities' instructions on disaster relief and reconstruction, said He Yong, deputy secretary of the CPC's Central Commission for Discipline Inspection.

He made the remarks at a conference on supervision and inspection of relief funds and supplies.

He instructed intensified supervision and inspection of medical, mud-clearing, infrastructure rebuilding, resident relocation and epidemic prevention operations.

He also ordered stepped-up supervision of the use of disaster relief funds, supplies and donations, and asked local officials to make public how they were utilizing the funds in a timely manner.

He said the principle of openness and transparency must be applied throughout the period of disaster relief work and reconstruction, and vowed to punish any misuse of relief funds and supplies.

The mudslide has killed 1,254 while 490 people remain missing as of Monday.
