China's Communist Party on Sunday formally reelected Xi Jinping the party's general secretary for another five years, paving the way for his historic third term as Chinese president.

The widely expected announcement comes after a week-long Communist Party Congress during which Xi further cemented his grip on power.

Party faithful endorsed his "core" position in leadership, and approved changes to the constitution making Xi's political vision central for China's future.

Chinese state media said Xi was also reappointed as head of China's Central Military Commission.

"I wish to thank the whole Party sincerely for the trust you have placed in us," Xi told journalists at Beijing's Great Hall of the People following the announcement.

He promised to "work diligently in the performance of our duties to prove worthy of the great trust of our Party and our people."

Xi set for unprecedented third term

Xi is now almost certain to be given and third presidential term during the annual legislative sessions in March.

In 2018, he scrapped the presidential two-term limit, allowing himself to rule indefinitely.

The 69-year-old leader is now expected by some to try to stay in power for life.

Delegates at the congress also chose a new Central Committee of 205 party officials — only 11 women were named to the committee. Central Committee members went on to elect the all-powerful Politburo Standing Committee, which Xi will again lead.

A list of officials in the new Central Committee revealed the replacement of four out of seven Standing Committee members, including Premier Li Keqiang, allowing Xi to install loyalists to the body.

Xi and the other Standing Committee members appeared for the first time as a group before reporters Sunday at the Great Hall of the People, the seat of China's ceremonial legislature in central Beijing.

Most powerful man since Mao

Since he took office in 2013, Xi has achieved a concentration of power like no modern Chinese ruler other than the modern country's founder Mao Zedong.

Xi has pushed forward the central role of the Communist Party, expanding state control over society and the economy.

He has also overseen China's rise as the world's second-biggest economy, a huge military expansion and a far more aggressive global posture that has drawn strong opposition from the United States.

Despite nearly unchecked power, Xi faces huge challenges over the next five years, including managing the nation's debt-ridden economy and the growing US rivalry.

'Winner takes all' in Chinese politics

Wen-Ti Sung, a lecturer in Taiwan Studies at the Australian National University (ANU) and currently based in Taipei, told DW that Xi's reappointment is proof that there is a "winner-takes-all situation in China’s politics today."

"Xi is showing to the world that they should stop trying to hope that there will be a ... factional power struggle within China today or going forward," he added.

“There will be no other power figure of comparable stature who can play a balancing role or be the focal point for organizing any meaningful organized opposition to check Xi’s power.”

Sung also warned that the Taiwan issue would likely remain in focus. Xi has threatened to retake the independent island by force that China considers its territory.

Meanwhile, Alfred Wu, an associate professor from the Lee Kuan Yew School of Public Policy in Singapore, told DW that those picked for the Politburo were people who have worked with Xi in the past.

"I would say he wants the fourth term and this group of people will support him when the decision-making about the fourth term comes. The overall structure is to make sure that he is No.1 in China for at least 10 years."

Wu said China's political system was "no different than a dictatorship," giving the example of Xi insisting that the country's zero-COVID strategy remains the best course of action, while the rest of the world reopens.

"'There's no checks and balances and information surrounding Xi will be very much like favoring Xi’s assumption. It’ll look like an echo chamber."
