The area has been in chaos since February 2003, when some armed groups started to attack government installations in the region. It is estimated that more than 10,000 have died and approximately 1 million have been left homeless in the fighting. But what really happened there? How can the international community help? Beijing Review reporter Yan Wei talked with Mirghani Mohamed Salih, Sudan's Ambassador to China, to get an insider's look at these widely scrutinized questions.展开更多
