It is my belief that most of the demand for horn comes from China and that the main demand is for medicinal use. After hundreds of years of Chinese demand it seems unlikely that the major volumes have moved to Vietnam, as some suggest. It seems more likely that China has set up Vietnam as a conduit into China. In recent years, about 1,200 rhino have been poached annually in South Africa and about 100 elsewhere in Africa. Add to that some horn that has been stolen from stocks and the total annual supply is about 1,400 horn-sets or 5,600 kg.
