The decision would further tighten his grip on China.It is possible that Mr Xi, 69, will remain in power for the rest of his life.To get more news about 20th national congress, you can visit shine news official website.
The historic move is due at a Communist Party Congress under way in Beijing - one of the most important meetings in the party's history.Some 2,300 delegates have gathered in Tiananmen Square's Great Hall of the People for a week.
About 200 of them will be selected to join the party's central committee, plus around 170 alternate members.The central committee will elect 25 people to the party's Politburo.And the Politburo will appoint the members of the Politburo standing committee.
Why is it important?
Mr Xi leads the world's second-largest economy and one of its biggest military forces.
Some analysts say he is likely to push China towards a more authoritarian political stance in a third five-year term."China under Xi is moving in a totalitarian direction," says Professor Steve Tsang of London University's School of Oriental and African Studies (SOAS).
"China under Mao was a totalitarian system. We're not there yet, but we're moving in that direction."Professor Tsang says the Congress could see changes to the party's constitution, with "Xi Jinping thought" being further enshrined as the party's guiding philosophy.
"Xi Jinping thought" is Mr Xi's brand of Chinese socialism, an assertively nationalist philosophy which is highly sceptical of private business.
Under his leadership the Chinese authorities have cracked down on powerful companies in several sectors of the economy."If that happens, they'll effectively make him a dictator," Prof Tsang says.
Henry Huiyao Wang, former Counsellor to the State Council of China, insists that Mr Xi should be credited with building his country into a prosperous, modernised society.
"China has its unique way", he says. Beijing is "trying to have a consultative democracy, not an American meritocracy".
China's top leadership team, to be unveiled at the congress, will set a huge range of policies.
Any hint of China's future direction will be followed closely around the world, particularly on the key challenges: economic, political, diplomatic and environmental.
Some analysts say the legitimacy of the communist government rests heavily on its ability to deliver higher incomes and good jobs for Chinese workers.
So bad economic performance in the next five years could spell serious political trouble for Mr Xi.
The congress will set the stage for a shake up of key economic roles including central bank governor and premier.
