"We have to figure out a mechanism to get those NGOs back in place, to reverse that decision, or to find some mechanism whereby we avert a enormous humanitarian crisis," Obama said on Monday after meeting with his special envoy to Sudan, retired air force general Scott Gration.
Gration is scheduled to arrive in Khartoum in the middle of the week on his first official visit to Sudan since Obama named him to the post earlier this month, the White House said on Monday.
Gration was nominated as Washington increases pressure on Sudan's President Omar al-Beshir following his expulsion of international aid groups from Darfur that worsened the humanitarian crisis.
The expulsion came days after the International Criminal Court issued an arrest warrant for Beshir for alleged war crimes and crimes against humanity carried out during the six-year conflict in Darfur.
UN Secretary General Ban Ki-moon on Monday repeated United Nations calls on Sudan to reverse its decision to expel the 13 aid groups from war-ravaged Darfur.
