In his first visit to the region, Negroponte toured the strife-torn Darfur region and criticized the Sudanese government for its response.
"When it comes to humanitarian access, the government of Sudan's record is not encouraging," Negroponte told a news conference in Khartoum. "The denial of visas (and) the harassment of aid workers have created the impression that the government of Sudan is engaged in a deliberate campaign of intimidation."
Negroponte urged Khartoum to disarm the Janjaweed, the Arab militias terrorizing Darfur refugees, and to allow additional U.N. and African Union peacekeepers into the region.
