To curb the destructive illegal ivory trade, the Convention on the International Trade in Endangered Species (CITES) announced in 2008 that it would suspend its ban on the international trade in ivory to allow a one-time legal sale of 108 metric tons of stockpiled ivory to China and Japan from four African nations. This partial-legalization was intended to flood the Asian market with legal ivory, driving black-market purveyors and the poachers who supply them out of business.
