BEIJING (CNN) -

China on Thursday unveiled the elite group of leaders who will set the agenda for the country for the next decade, the culmination of months of secretive bargaining and a carefully choreographed performance of political pomp.

The seven members of the powerful committee that sits atop the Chinese system strode out onto a stage in the Great Hall of the People in Beijing. They were led by Xi Jinping, who takes over from Hu Jintao as head of the Communist Party, which has ruled China for more than 60 years.

Xi is joined on the new Politburo Standing Committee, the party's top decision-making body, by Li Keqiang, who is expected to replace Wen Jiabao as premier early next year, and five other veteran party officials.

Although the committee's lineup is new, analysts said it appeared to be predominantly conservative and unlikely to bring about meaningful political changes in the world's most populous nation and second largest economy.

Xi also succeeded Hu as head of China's powerful Central Military Commission, which oversees major national security and military affairs. That makes for a cleaner transition than in the past two power handovers, when the former party chiefs held onto the key military role for years afterward, using it to keep exercising considerable power and influence.

A far cry from the relentless media campaigns and frequent public appearances of U.S. presidential candidates, the efforts to determine who ended up in China's most powerful posts have taken place behind closed doors, part of a once-in-a-decade leadership transition.

The focal point of the process has been the party's 18th National Congress that has unfolded amid heavy security in Beijing over the past week.

Despite the spectacular economic and social changes China has undergone in recent times, the party has maintained a tight grip on power and upheld its obscure methods for selecting its top leaders.

The consequences of the leadership handover are significant for the nation's 1.3 billion citizens, its neighbors in Asia and the United States, which is warily watching China's economic and military rise.

Standing in front of a huge landscape painting on Thursday, Xi brought a touch of cordiality to the start of his speech before a packed room of reporters, apologetically acknowledging that he and his party colleagues had kept their audience waiting by appearing later than scheduled.

But he quickly turned to serious matters, warning of the "many severe challenges" that the party faces.

He singled out corruption, remoteness from the general public, as well as undue emphasis on formalities and bureaucracy as particular concerns.

The secrecy and exclusivity of the procedure by which China's top leaders are selected, involving maneuvering and deal-making among senior party figures, leaves a lot of the country's citizens feeling detached from the process.

"Many ordinary people don't feel so excited or joyful about what's happening," said Lijia Zhang, a Beijing-based author. "People say, 'Oh, it's the party's business, nothing to do with us -- and we do not have a say in selecting the leader or the policy.' "

But Xi's speech had more of a human touch than many of those delivered by Chinese officials, and he addressed subjects close to the heart of many Chinese people and others around the world.

"Our people have great enthusiasm in life," he said. "They hope for better education, more stable jobs, more satisfactory income, more reliable social security, medical services with higher standards, more comfortable living conditions and a more beautiful environment."

What kind of changes Xi, 59, and those joining him on the party's most powerful committee are likely to usher in over the coming years remains shrouded in mystery.

"Xi Jinping is in many ways an unknown commodity," said Mike Chinoy, a former CNN correspondent and now a senior fellow at the University of Southern California's U.S.-China Institute. "He's risen to the top of the Chinese system by being very careful not to disclose what he really thinks."

The son of one of Mao Zedong's top lieutenants, Xi is considered a "princeling" because of his family's place in the Communist Party aristocracy. He is also believed to be close to the Chinese military.

Married to a popular folk singer for the People's Liberation Army, he has climbed through the party hierarchy, at one point holding the top job in the eastern metropolis of Shanghai. He is expected to inherit the title of president from Hu, 69, early next year.
