Beijing - China's most powerful political group was presented at a press conference at the end of the 19th National Congress of the
Communist Party of China on Wednesday.
The announcement was made at the Great Hall of the People. President Xi Jinping, continues as general secretary and leader one of the world's superpowers.
In a break with tradition, a successor was not made clear.
The omission cements Xi's term in the power seat for the next five years and, possibly, beyond, a day after his name "Xi Jinping Thought" was written into the constitution.
"I was re-elected general secretary of the CPC Central Committee. I see this as not just approval of my work, but also encouragement that
will spur me on," Xi told journalists.
Five new appointments were made to the seven-member Politburo Standing Committee, the country's most powerful group.

Vice-Premier Wang Yang, 62, a former party secretary of Guangdong province, has been appointed China's executive vice-premier.
Han Zheng, 63, the party secretary of Shanghai, has been promoted to lead the Chinese People's Political Consultative Conference.
They were joined by Zhao Leji, 60, who will lead the party's anti-corruption body; Li Zhanshu, 67, and Wang Huning, 62.
Xi said on behalf of the newly elected central leadership "I wish to express our heartfelt thanks to all other members of the party for the trust they have placed in us. We will work diligently to meet our duty."
He said the party must remain committed to a people-centred philosophy; to make steady progress in realising common prosperity for
all.
"The aspirations of the people to live a better life must always be the focus of our efforts."
He reiterated a pledge to establish a moderately prosperous society.
"A society to be enjoyed by each and every one of us... no one must be left behind." He resolved to eradicate poverty in China.
He told members of the press, which included international media, that China welcomed constructive criticism.
"We do not need lavish praise from others, however, we do welcome objective reporting and constructive suggestions."
He said he was "not angling for compliments, I would be content that my integrity fills the universe."
