The Chinese Communist Party's central committee announced on Sunday that it has proposed to remove the constitutional limit of two-terms (10 years) that can be served by the president and vice president. This move could allow incumbent Chinese President Xi Jinping to stay in power after 2022 – and possibly for life. The two-term safeguard had been put in place by former Chinese President Deng Xiaoping in the early 1980s, who has been lauded as the mastermind behind China's process of reform and opening-up, after decades of strongman rule under Mao Zedong.

That's what you call a personality cult.
