BEIJING, March 14 (Xinhua) -- The National People's Congress (NPC), China's top legislature, concluded its annual session Wednesday morning.

"The session was successful, with the further accumulation of common understanding, clarification of goals and reinforcement of confidence," said Wu Bangguo, chairman of the NPC Standing Committee, in a speech delivered at the session's closing meeting.

The session resulted in a full representation of the will of the people and the main concepts of the Communist Party of China (CPC), he said.

NPC deputies, with a strong sense of responsibility and commitment to their mission, exercised their duties as entrusted by the Constitution and law, he said.

At the session, the NPC adopted a number of important documents, including the government's work report, central budget and national economic and social development plan for 2012.

While deliberating the government's work report, deputies agreed that the country made progress in economic, political, cultural, social and environmental arenas in 2011, making for a good beginning for the 12th Five-Year Plan period (2011-2015), Wu said.

This year will be an important year for China, as the 18th CPC National Congress will be held later this year, Wu said.

The NPC will work for the steady growth and stability of the country as it welcomes the 18th CPC National Congress, he said.

The NPC also adopted several decisions on deputy elections for the 12th NPC and methods for the election of deputies to the 12th NPC from Hong Kong and Macao special administrative regions, as well as work reports for the NPC Standing Committee, the Supreme People's Court and the Supreme People's Procuratorate.

This year, the country will carry out elections for deputies to the next NPC using the same ratio for rural and urban areas for the first time, Wu said.

He pledged to ensure stable and orderly elections in line with relevant laws.

At the closing meeting, lawmakers adopted an amendment to the Criminal Procedure Law.

The revision embodies the constitutional principle of respecting and protecting human rights and is a key improvement to the current legal system of criminal prosecution and litigation, Wu said.

The NPC will work to educate the public about the revised law and prepare for its implementation, he said.

Since this year marks the last session of the 11th NPC, Wu said the NPC will learn from the experience gained in previous years and improve the quality of its work, he said.

Top CPC and state leaders Hu Jintao, Wen Jiabao, Jia Qinglin, Li Changchun, Xi Jinping, Li Keqiang, He Guoqiang and Zhou Yongkang attended the closing meeting.
