Premier Wen Jiabao on Tuesday vowed to put fighting corruption at the top of his agenda, at a special meeting of his new Cabinet.

The sole agenda item for the meeting was this year's anti-corruption work by the State Council, or Cabinet.

Wen said over-concentration of power plus ineffective supervision served as an important reason behind the spread of corruption. He stressed the importance of improving the system for supervising and containing over-concentration of power.
