Somewhat missed amongst the recent happenings in the UK and the US was the elevation of Xi Jinping, President of the People's Republic of China and head of the Chinese Communist Party, to the status of "core leader". Whilst some have be given to down-playing this, I think it significant in at least two ways.
Firstly, this signals a definite and final break with the Hu/Wen model of a dual leadership team of near-equals. There is absolutely no question now that Li Keqiang (the Chinese premier) is subordinate to Xi Jinping in a way that Wen Jiabao was not subordinate to Hu Jintao. Xi Jinping is the paramount leader of China and no talk from the CCP about how collective leadership still “must always be followed" can change the fact that having declared Xi to be a core leader on a par with Mao Zedong and Deng Xiaoping his word will be final.
The second significant aspect of this is that it further brings into question whether Xi will step down in 2022. Until relatively recently it was assumed amongst China watchers that the convention set by Hu/Wen of leadership teams serving ten-year terms together and then being replaced by the next generation of leadership would continue into the future. Whilst there was no real reason to believe this, and I myself did not believe it would carry on like this in a system with no checks and balances preventing the leadership simply arrogating power to themselves, Xi has now raised himself above such conventions and placed himself on a par with leaders who ruled China for decades. Moreover the generation of CCP leadership that might have replaced him is now significantly thinned and cowed as a result of Xi's "anti-corruption" campaign.
Back in the Hu/Wen years, one particularly silly argument you sometimes saw put forward by supporters of the CCP as to why they did not believe that China was a dictatorship was that China did not have a single dictator in charge at the top. Whatever validity this argument had is now completely wiped out. China now very clearly has a dictator - Xi Jinping - and there is now little preventing Xi staying on for another five, ten or even more years and becoming a Chinese Brezhnev.
