BEIJING- The National People's Congress (NPC), China's parliamentary body, concluded its annual session Sunday morning.

Zhang Dejiang, chairman of the NPC Standing Committee, presided over the closing meeting.

The NPC deputies approved a number of important documents, including the government work report, the national economic and social development plan and the central budget.

They endorsed the work reports of the NPC Standing Committee, the Supreme People's Court and the Supreme People's Procuratorate.

They adopted the revision to the Legislation Law.

The lawmakers also approved the resignations of two NPC Standing Committee members, Chen Jining and Chen Hao, at the closing meeting.

Chen Jining took the office as Minister of Environmental Protection in February. Chen Hao was appointed vice governor of southwest China's Yunnan Province last October and promoted to the governor in January.

According to the NPC rules, NPC Standing Committee members, elected from NPC deputies, are not allowed to take posts in governments, courts and procuratorates.
