Nearly 3,000 delegates from across China gathered at the imposing Great Hall of the People to sign off on the Communist Party's agenda during the two-week meeting of the National People's Congress.
The government presented reports outlining an economic growth target of around 6.5 percent for 2018, in line with expectations but lower than the 6.9 percent GDP increase in 2017.
It also announced an 8.1 percent increase for the defence budget to 1.11 trillion yuan ($175 billion) this year, giving the world's largest armed forces a boost after spending growth slowed in the previous two years.
But the spotlight was squarely on the party's most powerful leader since Mao Zedong, with legislators due to greenlight major constitutional amendments that will further cement Xi's authority.
The changes drafted by the Communist Party will remove the two-term limit for the presidency, engrave Xi's name in the state constitution and create a new national anti-corruption agency.
This would allow the 64-year-old leader to stay on as party chief, head of the military and president beyond 2023, when his second term is due to end.
"I support Xi Jinping. I support the constitution change," Zhou Feng, a delegate from Shanghai, told AFP.
Another delegate from central Henan province said "Xi Jinping is great" but several other legislators refused to answer questions about the amendment
Analysts have warned that the move carries risks as it ends a "collective" model of leadership that maintained stability after Mao's chaotic reign from 1949 to his death in 1976.
NPC spokesman Zhang Yesui downplayed its significance, saying Sunday it would merely align the presidency with the titles of Communist Party general secretary and Military Commission chairman, which do not have term limits.
"It is conducive to uphold the authority of the Central Committee of the party with comrade Xi Jinping at the core and also to unify leadership," Zhang said.
Censors have worked furiously to stamp out dissenting voices on social media, blocking dozens of words from "disagree" to "emperor".
He has also pursued a relentless but popular campaign against corruption that has punished more than a million crooked party officials.
Hua Po, a Beijing-based political commentator, said Xi was handed "a mess" when he took office five years ago and needs more time to finish the job.
"One of the greatest tasks after he took office was to remove all threats to the party and state. To do this, it is not enough for him to serve only two terms," Hua told AFP.
"The Chinese system is a system that requires strong leaders, but it's not easy to train a strongman. Xi needs more time to find and train the right successors," he said.
"If Xi transfers power on time, it is likely that the power will be returned to the hands of the corrupt groups and the elite class and all his efforts in the recent years will be wasted."
While there is no doubt that the NPC will approve the amendment, analysts say legislators could voice their displeasure by abstaining or voting against the appointments of certain Xi allies to top posts.
"We don't hear about opposition to his life tenure because of censorship," said Willy Lam, politics professor at the Chinese University of Hong Kong.
"But there is opposition within the regime from people who think that this is outrageous, that he is going too far, that he has launched a coup against the party."
For eastern Fujian province delegate Huang Lei, "the most important thing for the congress is to focus on how to improve people's livelihoods".
She said she hopes for new concrete policies including more investment in environmental protection.
"There has already been a lot of progress and this should continue to serve the people," she said.
