China's recent thrust into Africa in a rush for resources is a major factor in the illegal rhino horn and ivory trade, analysts believe, because China remains the largest market. Rhino horn, made of keratin, the same substance that forms fingernails, hooves, feathers and hair, has long been used in Chinese medicinal tonics.
Zimbabwe's collapse added to the problem, with corrupt government, army and wildlife officials reportedly involved in poaching and smuggling rhino horn and ivory. The airport in that country's capital, Harare, is reportedly a key transit hub.
In South Africa, Vietnamese diplomatic officials have allegedly been involved in rhino horn buying and smuggling. Reports in Vietnam that a government official was "cured" of cancer by rhino horn appear to have spurred Asian demand.
Many fear that the Asian market is so ancient and entrenched, there's not much a small group of farmers can do to save the species. Some support the idea of rhino farming -- regularly pruning horns, which grow back -- to meet the demand and drive down prices. Others argue that legalizing the trade would only fuel demand, putting the creatures at even more risk.
South Africa is home to the world’s biggest population of white rhinos. There are about 15,000 white rhinos remaining worldwide. As of February 18th, 2009, they declared a moratorium on trading in products made from their horns and will limit hunting of the endangered animals. The moratorium will have an immediate effect. Hunters will only be allowed to kill one white rhino a year per person. The black and white rhinos are often poached and their horns smuggled to Yemen and Asia. In Yemen the horns are used to make dagger handles. In Asia they are used for medicines.
