Jonathan Anderson, an economist with UBS, sees more opportunities than challenges for China.

The only factor that could pose significant risk in China's social and political development, he said, would be sudden economic recession. Yet judging from the present circumstances, China's economy is likely to maintain robust growth in the next five years.

In his analytical report on China published last month, Anderson said the past five years of double-digit growth was a legacy to China's new leadership, including sustained rural income rise, lower unemployment rate, revenue increases, stable FDI inflows and the public's confidence in their government.

How to narrow the income gap, balance GDP growth with environmental protection, maintain social justice and step up administrative reforms are among the major challenges facing the Chinese government in the coming five years, said most NPC deputies attending the annual parliamentary session.

"The central issue is how to implement the 'Scientific Outlook on Development', and how to maintain stable and balanced development while ensuring all members of society benefit from such development," said Shen Jiacong, an NPC deputy from Tianjin.

To ease the impact of economic growth on environment, China aims to cut energy consumption used to generate per unit of GDP by 20 percent and major pollutants emissions by 10 percent between 2006 and 2010.

Premier Wen Jiabao has said the country will continue its drive to close down backward production facilities in the electricity, steel, cement, coal and papermaking industries, and develop advanced production facilities in these industries.

Yet some NPC deputies say China need also to take into consideration the regional differences, promote coordinated development of different regions and encourage financial institutions to extend more loans to the underdeveloped regions.

"While the developed eastern region is already at an advanced stage of industrial development and needs to cut emissions, most central and western regions are still at a preliminary stage of industrialization," said Wu Changyuan, a deputy from the southernmost island province of Hainan. "It's not possible to cure different symptoms with the same therapy."

These call for all-round reforms in the political, social and cultural sectors in the coming five years, said Chi Fulin, executive president of the China Institute for Reform and Development.

The government reshuffle plan, adopted by the NPC session on Saturday, has apparently put the government on the frontline of China's political reforms.

Observers say the government reform, the sixth in 30 years, will be an important exploration in restricting power and supervising the exercise of power by different government departments. "It's crucial for China's overall development in the coming five years," said Gong Ke, NPC deputy and president of Tianjin University.
