China's Ministry of Supervision said Thursday it would enhance supervision to key sectors and leading officials this year to ensure clean and efficient work in promoting the country's sound economic and social development.

The supervision and examination would target corruption in project construction, real estate development and land management, as well as corruption behind major accidents, the ministry said in a circular outlining major works in 2010.

The ministry would investigate officials who meddled in construction projects against relevant regulations to seek personal gains, staff of supervisory organs who were negligent of duty or took bribes, and those who involved in serious commercial bribery cases, the circular said.

The ministry vowed "zero tolerance" for these cases, it said.

The ministry promised to step up its efforts this year to ensure the implementation of the central government's major arrangements for accelerating the adjustment of economic growth mode and promoting steady and fast economic development.

It would also strengthen supervision and examination to make sure local governments will take measures to check the rocketing real estate price in some cities to ensure the sector's healthy development, it said.

"Lazy and incapable" officials would also be targeted in the supervision to ensure efficiency of government work, according to the circular.

China has intensified its fight against corruption recently.

In its latest effort, the Communist Party of China (CPC) Central Committee Tuesday listed 52 unacceptable practices in an ethics code for CPC cadres to follow.

The code forbids conducts including accepting cash or financial instruments as gifts, and using their influence to benefit their spouses or children with regards to their employment, stock trading or business.
