China's top legislature will closely supervise the government's economic work this year to ensure stimulus plans to be efficiently implemented, top legislator Wu Bangguo said on Monday.

A key task for the Standing Committee of the National People's Congress (NPC), the parliament, is to improve supervision to ensure implementation of major policy decisions and successful accomplishment of this year's tasks for economic and social development, said Wu.

"We will devote a great deal of effort to promoting steady and rapid economic development and transforming the pattern of economic development, "Wu, chairman of the NPC Standing Committee, said when delivering a work report of the committee.

Premier Wen Jiabao on Thursday proposed to the parliament a massive economic stimulus plan, which included a 4-trillion yuan (US$585.5 billion) two-year investment, to curb economic downturn amid global financial crisis.

The NPC Standing Committee, which has the power to decide upon major state issues when the NPC is not in session, will read and deliberate a series of work reports of the State Council, the cabinet, concerning economic development, Wu said.

High on the supervision agenda are reports on transforming the pattern of economic development, promoting development of small and medium-sized enterprises, preventing and controlling air pollution, as well as reports on the 2008 central government final budget and auditing work, Wu said.

The NPC Standing Committee normally meets once every two months. It may hold interim meetings when there is a special need.

Wu said the NPC Standing Committee will also improve supervision over issues affecting people's wellbeing.

In the coming year, the Standing Committee will hear and deliberate the State Council's special work reports on social safety net, employment, reconstruction in areas struck by the May earthquake last year, and vocational education, Wu said.

The legislature will also review the Supreme People's Court's report on improving civil law enforcement, and the Supreme People's Procuratorate's report on investigations into duty dereliction and rights infringement cases, Wu said.
