Xi Jinping was elevated to the pantheon of China's most powerful leaders on Tuesday as his name was enshrined in the Communist Party constitution alongside Chairman Mao.
The inclusion of Xi's eponymous guiding philosophy for the nation at the end of a week-long congress could lay the foundation for him to remain China's paramount leader far beyond his upcoming second five-year term.
Communist China's founder Mao Zedong, and the architect of its market reforms, Deng Xiaoping, are the only other Chinese leaders to have their names in the document, and only Mao was alive when his was included.
Xi, 64, presided over the congress's closing session where some 2,300 delegates approved the constitutional amendment to include "Xi Jinping Thought on Socialism with Chinese Characteristics for a New Era."
The concept places a heavy emphasis on the party's role in governing every aspect of the country from the economy to what people are writing on social media.
"We must work tirelessly and forge ahead on the journey of realising the rejuvenation of the Chinese nation," Xi, who is due to be reappointed as party chief on Wednesday, told the congress in concluding remarks.
Xi's predecessors Jiang Zemin and Hu Jintao had their concepts included in the constitution, but without their names and only when they retired after two terms.
"China has a tradition of combining emperor and teacher, which means that the emperor is also the thought leader. Xi achieved it at the end of his first term. That's rare in our history," Chinese political scholar Hu Xingdou said.
'New era'
When he opened the gathering last week, Xi declared that China had entered a "new era" with the ambitious goal of becoming a "global leader" by mid-century.
Xi has sought to portray himself as a responsible global leader while US President Donald Trump trumpets a nationalist "America First" policy and the European Union grapples with Britain's exit.
His blueprint foresees no change in the single-party political system, and gives no sign that crackdowns on human rights activists will ease.
Some of his goals, such as building a modern military by 2035, go beyond the end of his second term, a hint that he foresees himself staying at the centre of China's political life for years to come.
At the closing session, Xi said the congress established "the goal of securing a decisive victory in building a moderately prosperous society in all respects and then embarking on a journey to fully build a modern socialist China".
'Full control'
Despite Xi's rising power, the composition of the Politburo Standing Committee, the body that controls power, will still be crucial to his efforts, said Willy Lam, politics professor at the Chinese University of Hong Kong.
Xi and Premier Li Keqiang are expected to remain on the committee while the five other current members are supposed to step down under an informal retirement age set at 68.
There is no agreement among China-watchers about who will end up on the committee, or if anybody will emerge as a potential successor.
If the right allies are named, Lam said, it would show that "he has full control over the Politburo Standing Committee".
