premise: China has been, and continues to be, a major supplier of light weapons to the government of Sudan and many of the neighbouring states, said Ernst Jan Hogendoorn, one of four U.N. experts on an panel which recommended 17 players in the Darfur conflict be sanctioned for obstructing peace. The panel's report found Sudan's neighbours Chad, Libya and Eritrea had supplied weapons to Darfur and that most of the small arms and ammunition in the region were Chinese. "Chinese arms and ammunition are relatively cheap compared to other suppliers -- some also argue that China asks fewer questions," said Hogendoorn.
hypothesis: China, Chad, Libya and Eritrea sell arms to Sudan.
