China will push forward its anti-corruption legislation by drafting a national supervision law this year, Fu Ying, spokeswoman of the Fifth Session of the 12th National People's Congress, said on Saturday.

Amending the Administrative Supervision Law into a more powerful national supervision law is underway and the revised version is scheduled to be submitted to the NPC Standing Committee for review within the year, Fu said at a press conference.

"This is a substantial measure to push forward China's anti-corruption legislation," she said, adding that strengthening supervision is a systematic project.

"The pilot practice will offer valuable experience for the future expansion of the new supervision system," Fu said.

In response to reporter's question about whether China will amend the Constitution as the supervision system reform is a fundamental political reform, Fu said that amending the Constitution is a key issue of the State, and it should be carried out under the leadership of the Communist Party of China and must follow stipulated procedures laid out in the Constitution.

"We'll timely inform the public if there's any information in this sector," she said.
