China's ruling Communist Party is expected to hand a third five-year term to Xi Jinping, arguably the most powerful Chinese leader since Mao Zedong in the 1970s.
The decision - which comes after a two-term limit was abolished in 2018 - would further tighten his grip on China.
It is possible that Mr Xi, 69, will remain president for the rest of his life.
The historic move is due at a Communist Party Congress in Beijing beginning on 16 October - one of the most important meetings in the party's history.
Xi Jinping currently holds three top positions
As General Secretary he is the chief of China's Communist Party.As president he is China's head of state.As Chairman of China's Central Military Commission he commands the country's armed forces.
He is also referred to as Paramount or Supreme leader.
Mr Xi is likely to retain the first two titles, party General Secretary and Central Military Commission chairman at the party congress - which takes place every five years - and the presidency at the annual National People's Congress in Spring 2023.
