It is not a little worse than Europe and America. Europe, especially Britain, France and Germany are the best, and Russia is also a powerful country in mathematics. In Asia, to tell the truth, only Japanese mathematics is slightly better, and South Korea and China are really bad. There are only three mathematicians in China-Qiu Chengtong, Chen Shengshen and Tao Zhexuan, but none of them are from China. Mr. Chen Shengshen is the best. He is one of the important founders of modern differential geometry. There are not many people like Chen Jingrun in the world.
