When President Hu Jintao opens the 17th Chinese Communist Party congress on October 15, he will be seeking to oust key rivals, name a successor and finally emerge from the shadow of his once powerful predecessor, Jiang Zemin.

A stronger grip on power could allow Hu to speed up his drive to balance breakneck but uneven economic growth, improve the lives of poor farmers, build a social safety net, halt rampant environmental degradation and promote “fair and just” policies.

The 58-year history of the People's Republic is littered with the names of heirs apparent who died in prison, in mysterious circumstances or under house arrest. This time, when the 2,217 party delegates pack into Beijing's Great Hall of the People, the all-important question is whether Hu, who doubles as state president, can neutralise Jiang's lingering off-stage influence.

“Hu is now the biggest stakeholder and hopes to become the majority stakeholder,” political commentator Liang Kezhi said. Even in the months before the congress there have been high-level political casualties.

A top-ranking rival, the Party boss in Shanghai, Jiang’s traditional power base, now faces trial for corruption. The finance minister resigned amid allegations of a sex scandal. The food and drug safety chief was tried and executed for corruption.

But the 81-year-old Jiang’s influence, while waning, has not been eclipsed. One key test of Hu’s growing confidence will be whether he can ease out Jiang allies Zeng Qinghong and Jia Qinglin from the all-powerful Politburo Standing Committee, now down to eight members after the death of another Jiang loyalist, Vice Premier Huang Ju, in June.
