China's five-yearly Communist Party Congress wrapped up on Saturday with President Xi Jinping set to emerge from the event as leader for an unprecedented third term.

Xi delivered a speech starting about midday (0400 GMT) in one of the final events of the week-long gathering at Beijing's Great Hall of the People.

"Dare to struggle, dare to win, bury your heads and work hard. Be determined to keep forging ahead," he told the party faithful.

His speech ended a week of largely rubber-stamp meetings among 2,300 party delegates, who were selected by the party to approve a reshuffle of its leadership.

However, in an unexpected move at such a heavily choreographed event, former leader Hu Jintao was led out of the closing ceremony. No official explanation was given.

The new Central Committee of around 200 senior Party officials was elected shortly after 11 am Saturday, state media agency Xinhua reported, without disclosing a full list of members.

Delegates also voted to endorse Xi's "work report" delivered at the Congress's opening last Sunday and rubber-stamped a resolution on the Party's constitution.

Xi is now widely expected to be unveiled as general secretary on Sunday, shortly after the first meeting of the new Central Committee.

This will allow Xi to sail through to a third term as China's president, due to be announced during the government's annual legislative sessions in March.

Xi previously abolished the presidential two-term limit in 2018, paving the way for him to rule indefinitely.

The weekend will also see the new Central Committee approve a reshuffled 25-member Politburo, as well as a Politburo Standing Committee — China's apex of power — of around seven people, which analysts expect to be stacked with Xi allies.

At Sunday's Congress opening ceremony, Xi delivered a 105-minute speech lauding the party's achievements and glossing over domestic problems such as the stalling economy and the damage wrought by his harsh zero-Covid policy.
