it is very difficult to trade medical device and medicines acros
it is not like you buy one stuff here and sell it to china or vice verse. there are heavy regulations.
If a medical device wants to be sold in china, the sponosr or delegate needs to get marketing approval from China's SDA (china's FDA) by doing required clinical trials. it is a huge hurdle which is not small fish's business. After marketing approval, then you can sell it by a variety of ways. Due to heavy corruptions, one needs a lot of money to open the door to the buyers. forget about this business unless you have a well-organized, dedicated full-time team.
