BEIJING (AFP) - Xi Jinping has joined the pantheon of Chinese leadership two decades after bursting onto the scene as a graft-fighting governor who went on to earn comparisons with Mao Zedong in his quest for unrestricted power.

The rubber-stamp parliament further enhanced Xi's considerable power on Sunday when it approved - by an overwhelming 99.79 per cent of vote - a constitutional amendment abolishing presidential term limits.

The move allows the 64-year-old Xi to remain in power for as long as he wishes, ruling as a virtual emperor, and is the latest feather in the cap of a Communist "princeling" who is re-making China in his own image.

Xi, who was given a second term as the party's general secretary at the five-yearly party congress in October, has amassed seemingly unchecked power and a level of officially stoked adulation unseen since Communist China's founder Mao.

Even though his father Xi Zhongxun - a renowned revolutionary hero turned vice premier - was purged by Mao during the Cultural Revolution and Xi himself sent down to work in the countryside during the tumultuous times, Xi has remained true to the party which will mark the 100th anniversary of its founding in 2021.

Xi is the first Chinese leader to have been born after 1949, when Mao's Communist forces took over following a protracted civil war.

The purging of his father led to years of difficulties for the family, but he nevertheless rose through its ranks.

Beginning as a county-level party secretary in 1969, Xi climbed to the governorship of coastal Fujian province in 1999, then party chief of Zhejiang province in 2002 and eventually Shanghai in 2007.

That same year, he was appointed to the Politburo Standing Committee, the apex of political power in China.

Following Mao's disastrous economic campaigns and the bloody 1966-76 Cultural Revolution, the Communist leadership sought to prevent further chaos by tempering presidential power through a system in which major personnel and policy decisions were hashed out by the ruling Politburo Standing Committee.

The move helped prevent political power from becoming too concentrated in the hands of a single leader but was also blamed for policy indecision that led to growing ills such as worsening pollution, corruption and social unrest.

But "Xi Dada" ("Big Uncle Xi"), as he has been dubbed by Communist propaganda, has broken sharply with that tradition since taking over as president in 2013 and now looms over the country in a deepening cult of personality.

He has used crackdowns on corruption and calls for a revitalised party to become the most powerful Chinese leader in decades.

Fighting graft and upholding party leadership were already central to him when he spoke to AFP in 2000.

At the time, Xi vowed to root out corruption following a US$10 billion smuggling scandal, but ruled out political reform to confront the problem, saying he would work within the one-party structure and system of political consultation and "supervision by the masses".

"The people's government must never forget the word the 'people' and we must do everything we can to serve the people, but to get all the government officials to do this is not easy, in some places this is not done very well and in other places it is done very badly," Xi told AFP.

'Chairman of everything'

Xi's face now graces the front page of every paper in the country, while his exploits and directives headline each night's evening news.

Shops sell commemorative plates and memorabilia with his image alongside Mao's and he has accumulated so many political and military titles - from president, to Central Military Commission chairman and party "core" - that he has earned the nickname "Chairman of Everything".

The Communist Party's power-broking congress in October confirmed Xi's induction into the leadership pantheon alongside Mao and market reformer Deng Xiaoping by writing his name and political ideology into the party's constitution.

While calling for China's "great rejuvenation" as a world power, Xi has cultivated a personal image as a man of the people who dresses modestly and buys his own steamed buns at an ordinary shop.

Following a divorce from his first wife, Xi married the celebrity soprano Peng Liyuan in 1987, at a time when she was much more famous than him.

The couple's daughter, Xi Mingze, studied at Harvard but stays out of the public eye.
