They are just trying to save face
Chinese gov's geopolitical planning relies in china being ''cheaper'' than the western countries at least 20 years more, if Europe and the USA lose purchase power China is among the first losers, in fact, they likely will devalue the yuan as USA and Europe's monetary stimulus hit the markets
This is all just Chinese propaganda as the savior of the world from covid-19. Repeated reports about China's contribution to WHO and China's role as a global commander in dealing with a pandemic corona.
China precisely Xi Jing Ping really controls the media, to voice the news of justification, not the truth. So there is no news that leads to China's degradation to overcome corona. In addition to the interests of China, President Xi Jing Ping also wants his prestige to remain above the present condition even some vocal officials who voiced China's inability to cope with corona were immediately fired and also replaced by his position in the party.
Xi also silenced and imprisoned his critics, including a real estate tycoon and previously one of the richest and most powerful people in China for publishing articles describing Xi as an emperor who had no clothes and was like a clown.
Many oppositions opposed Xi's policies but were always successfully removed, many internal parties began to doubt the credibility of Xi's policy and operations strategy so that the CCP's political elite movement emerged to depose Xi. The mistrust that arises in one's own environment is more dangerous to destroy Xi from within than an enemy that is clearly categorized as anti-China.
