China's 20th Communist Party Congress: What you need to know

China's 20th Communist Party Congress wraps up this weekend, with Xi Jinping poised to clinch his third five-year stint in charge - a mandate that would secure him as the country's most powerful ruler since founding leader Mao Zedong.

* Xi opened the week-long, twice-a-decade session on Sunday with a speech touting China's fight against Covid-19, the party's safeguarding of national security, maintaining social stability, protecting people's lives and taking control of the situation in Hong Kong, which was rocked by anti-government protests in 2019. He also called for accelerating the building of a world-class military.

* Little is known about who will be promoted into which key roles on the Politburo and its seven-member Standing Committee this weekend - although the number of women is likely to remain very small. Here are some of the leading contenders and some scenarios to look out for.
