WASHINGTON  The Obama administration has formulated a new policy for Sudan that proposes working with that country’s government, rather than isolating it as President Obama had pledged to do during his campaign.

In an interview on Friday, President Obama’s special envoy to Sudan, Maj. Gen. J. Scott Gration, retired, said the policy, to be announced Monday by Secretary of State Hillary Rodham Clinton, would make use of a mix of “incentives and pressure” to seek an end to the human rights abuses that have left millions of people dead or displaced while burning Darfur into the American conscience.

General Gration said the administration would set strict time lines for President Omar al-Bashir of Sudan to fulfill the conditions of a 2005 peace agreement that his government signed with rebels in southern Sudan.

Under that agreement, independence for southern Sudan is to be put to a vote in 2011.

“To advance peace and security in Sudan, we must engage with allies and with those with whom we disagree,” said a statement of the policy that was obtained by The New York Times.
