BEIJING (AP) — President Hu Jintao stepped aside as ruling party leader today to clear the way for Vice President Xi Jinping to take China’s helm as part of only the second orderly transfer of power in 63 years of Communist rule.

In a possible break from tradition, Hu may also be giving up his post as head of the commission that oversees the military, which would give Xi greater leeway to consolidate his authority when he takes over. A top general indicated Hu would not stay on in the military post.

Hu and other senior leaders mostly in their late 60s are handing over power to leaderin waiting Xi and other colleagues in their late 50s over the next several months. The new leadership faces daunting challenges including slowing growth in the world’s No. 2 economy, rising unrest among increasingly assertive citizens and delicate relations with neighboring countries.

In keeping with the widely anticipated succession plans, Hu was not re-elected a member of the party’s Central Committee on the final day of a pivotal party congress, showing that he’s no longer in the political leadership.

Delegates said they cheered when the announced results of secret balloting showed that Xi had been unanimously chosen for the committee, a step toward being named to the top-most panel, the Politburo Standing Committee, and becoming party leader as expected on Thursday. Li Keqiang, designated as the next premier, also was elected to the Central Committee of 205 full members.

“We were very happy, and the whole assembly responded with warm applause,” said delegate Si Zefu, president of the Dongfang Electric Corp. based in the central city of Chengdu.

Previous outgoing leaders, including former President Jiang Zemin, have held onto the military post for a transitional period to extend their grip on power. Asked by Hong Kong reporters if Hu would retain his chairmanship of the military commission, Zhang Qinsheng, deputy chief of general staff of the People’s Liberation Army, said the central leadership “had no such arrangements.”

Zhang Lifan, an independent scholar in Beijing, said relinquishing all posts would be Hu’s contribution to China’s political reform.

“It will be an important political legacy, as he will break the bad tradition of holding onto power by outgoing officials,” he said.

As the final day of the secretive, weeklong congress drew to a close in the Great Hall of the People, and after reporters were invited in to watch the proceedings, Hu reminded party leaders of the “glorious mission and heavy responsibilities” entrusted to them.
