BEIJING - China's new leader Xi Jinping pledged a cleaner, more efficient government Sunday as the country's ceremonial legislature wrapped up a pivotal session that installed the latest generation of communist leaders in a once-a-decade transfer of power.
The new leadership has stressed it will make a priority of social spending and other measures to spread prosperity more evenly and narrow a politically volatile gap between China's wealthy elite and poor majority, as well combat endemic corruption that has angered the public.
"In face of the mighty trend of the times and earnest expectations of the people for a better life, we cannot have the slightest complacency, or get the slightest slack at work," Xi told the nearly 3,000 delegates at the congress' closing ceremony at the Great Hall of the People in the heart of Beijing.
"We must resolutely reject formalism, bureaucratism, hedonism and extravagance, and resolutely fight against corruption and other misconduct in all manifestations," Xi said.
Xi, already the country's overall leader since being named Communist Party general secretary in November, was installed as president during the 13-day session ending Sunday, and the party's No. 2 leader, Li Keqiang, was named premier.
On Saturday, the rubberstamp National People's Congress endorsed the leadership's slate of veteran technocrats -- many with strong international experience -- to staff a Cabinet charged with overhauling a slowing economy and pursuing a higher global profile for the country without triggering opposition.
They take charge at a time of difficult transitions. With the economic model that brought decades of high growth sputtering, the government is looking to transform the world's second-largest economy by nurturing self-sustaining growth based on domestic consumption and technology industries instead of labor-intensive exports and investment.
A more assertive foreign policy, cyber-hacking and years of scouring the world for resources have touched off nervousness among China's neighbors and the U.S., and set off a small but potentially threatening backlash against Chinese investment in Africa and Latin America.
The new leaders embarked on their careers as China was re-entering world trade and politics after decades of isolation. They are representative of how far China's reach extends, having more international exposure than their predecessors.
"They will have a more rational and objective view of China and the relationship between China and the rest of the world," said Zhu Feng, a professor of international relations at Peking University. "It means they are more cognizant of how the world reacts to China and that they will be more active in seeking changes. That's a good thing."
Among the appointments endorsed Saturday, trade envoy Gao Hucheng, who has a Ph.D. in sociology from the University of Paris and has worked in Europe and Africa, was named commerce minister. Appointed finance minister was Lou Jiwei, chairman of China's multibillion-dollar sovereign wealth fund and a fixture in international financial circles. Their appointments are likely to reassure trading partners and financial markets about policy continuity.
Central bank governor Zhou Xiaochuan, another prominent figure, was also kept on.
Similarly, Wang Yi, a career diplomat with experience working on some of China's knottiest diplomatic issues, was named foreign minister. A former ambassador to Japan, Wang worked with the United States in nuclear disarmament talks with North Korea and has charted Beijing's successful outreach to Taiwan, healing an estrangement from their separation in the Chinese civil war.
For defense minister, leaders chose Gen. Chang Wanquan, a soldier from a poor farming family who has commanded the manned space program.
The economy is limping out of its deepest slump since the 2008 global crisis, but a dip in February consumer sales and factory output has spurred fears that the rebound might be faltering. Economic growth fell to 7.8 percent last year, China's weakest performance since the 1990s.
Weaker consumer spending has set back rebalancing plans by forcing the government to support the recovery with spending on building subways and other public works.
"We think China made some progress on rebalancing in 2012; the real work will fall to new Premier Li," Standard Chartered economist Stephen Green said in a report.
A test for the new government will be if, as reformers advocate, it curbs the dominance of state industry and encourages private companies that generate the new jobs and wealth needed to keep incomes rising.
That is likely to provoke resistance from politically powerful companies, some of which in energy, telecommunications and other industries are so large that their bosses rank higher in the government hierarchy than the regulators who oversee them.
The transfer of power to new leaders has been in the works for years and saw divisive bargaining among party power brokers and their factions.
