Implying that Chinese science is bad?
Chinese universities absolutely dominate in chemistry: https://www.nature.com/nature-index/institution-outputs/gene...
By my count, 18/20 top universities for chemistry research is in China. The first US university in chemistry is MIT at 23.
One of the attempts is by USTC, the second best university in the world for chemistry research according to the Nature link.
China's lead in chemistry research is also translating directly to real world applications. For example, CATL and BYD combined own more than 50% of the car battery market. Six of the top 10 car battery makers are Chinese companies. [0]
It's not surprising that most of the first replication attempts are from China.
