This is a half truth. Yes, that award was made to Mugabe, but not by the Chinese government.
This is what the Diplomat magazine ( a western publication) had to say about it:
The Confucius Peace Prize was set up in 2010, after Liu received his Nobel Peace Prize. It was established by a private association of Chinese citizens based in Hong Kong, known as the Association of Chinese Indigenous Arts in the People’s Republic of China. Liu Zhiqin, a prominent businessman who originated the proposal to set up a uniquely Chinese prize, said at the time: “We should not compete, we should not confront the Nobel Prize, but we should try to set up another standard.”
Part of the misunderstanding that the Confucius Peace Prize was endowed and supported by the Chinese government had to do with the Hong Kong group’s assertions that it was working with the Chinese Ministry of Culture (which the ministry has since vehemently denied). Additionally, China’s soft-power spreading Confucius Institutes had been founded in the mid-2000s and were still spreading globally, suggesting to some that the Confucius Peace Prize was a similar push for Chinese values and soft-power.
Since its inception, the Confucius Peace Prize has been awarded roughly around the same time as the Nobel Peace Prize. Before Mugabe, Kofi Annan, the former UN Secretary-General, agricultural scientist Yuan Longping, Russia’s Vladimir Putin, and Fidel Castro of Cuba have been recipients. Additionally, former KMT secretary-general Lien Chan of Taiwan won the inaugural edition of the prize, a development the Taiwanese government found “amusing.”
Differences in values certainly exist between China and the West, but it’s important to understand that the government of the People’s Republic of China hasn’t quite responded to perceived Western affronts with the sort of pettiness that the Confucian Peace Prize represents. So remember, while it is outrageous that Robert Mugabe would win anything called a “Peace Prize,” it’s been given to him by a private group of Chinese citizens based in Hong Kong with no affiliation with the Chinese government.
So if the Diplomat report is correct, the award is made by a private group of Chinese citizens in Hongkong,.and NOT by the Chinese government in Beijing.
Its certainly true that the Chinese government maintains a relationship with Zimbabwe. The Chinese government refuses to be judgmental and play the sort of games that the US government plays, applying sanctions and excluding nations that they perceive as "enemy." For example, Iraq was demonised, but Saudi Arabia, which some may judge as worse than Iraq ever was, is allowed to be paart of the USA's club.
