Laura Rozen reports that U.N. Secretary-General Ban-Ki Moon is in Washington this week and will be meeting with President Obama Tuesday, March 10. Although the visit appears to be framed as a general introduction that will cover topics ranging from nuclear nonproliferation to climate change, NSC spokesperson Mike Hammer particularly noted, “This will also be an opportunity for the Secretary General and the President to discuss the humanitarian situation in Sudan." Given the relatively watered-down statements that came out of both the White House and U.N. Headquarters last week, it’s good to see that U.N. Ambassador Susan Rice, a forceful advocate for Darfur, will be joining the meeting tomorrow. Hopefully she can help speed the policy process on Sudan, which has been languishing in a review fast outpaced by current events. Other welcome elements of the Secretary-General’s itinerary: meetings with Senate Foreign Relations Committee Chair John Kerry (who has been doing some thinking about No-Fly Zones), and Vice President Biden, who said of Darfur back in April 2007: “I would use American force now.”
