Why don't China sell many foreign medicines?

are foreign medicines cheap? You are talking about generic drugs, right? Our country's drug research and development level is low, and we can only wait for the drugs of foreign big pharmaceutical companies to pass the patent period before copying. For example, Lipitor (lipid-lowering drug), which was the number one in sales in 29, expired for 12 years. Now many domestic manufacturers are copying it, and the level is not high. It is also imitation. India's imitation drugs are cheap and the quality is good. Some people brought drugs back from India for sale privately and were sentenced.
