Explanation:

This question refers to the text "Killing Fields: Ivory Trade Puts African Elephants in Harm's Way." In this text, the author talks about the ivory trade. He explains how damaging it is for the elephants of Africa, and how it is important to take measures to protect them. The author also discusses the motivations of poachers, and he tells us that Chinese citizens drive trade. He says that:

"Chinese citizens are the driving force behind the ivory trade, the report said. About 5,000  Chinese people live and work in Sudan. They purchase about three-quarters of all ivory items in Sudan. Although the Chinese government has tried to intercept illegal ivory imports, China is the largest importer of illegal ivory."
