Shanghai Communist Party chief Li Qiang followed Xi onto the stage at the Great Hall of the People as the new leadership team was introduced, meaning he is likely to succeed Li Keqiang as premier when he retires in March.
The other members of the seven-man Standing Committee, China's top governing body, are Zhao Leji and Wang Huning, who return from the previous committee, and newcomers Cai Qi, Ding Xuexiang and Li Xi. Li Qiang is also new to the Standing Committee.
All are perceived to have close allegiance to Xi, 69, who was also re-appointed on Sunday as chairman of the Central Military Commission.
