"Although we don't like the resolution, we are already committed to the implementation of its measures on the basis of the agreement that was concluded with (UN) Secretary General Kofi Annan," the minister of state for foreign affairs, Neguib al-Kheir Abdul Wahab, told AFP.
Abdul Wahab was referring to an agreement between the government and the United Nations earlier in July under which Sudan agreed to implement a series of measures regarding the war-torn region.
They include a lifting of restrictions on humanitarian aid, facilitating access and reining in pro-government Arab militias blamed for atrocities in Darfur, where thousands of people risk starvation.
Abdul Wahab said the UN resolution "was unnecessarily rushed by the Security Council, although there is nothing new in it".
He also complained that while the deal with Annan gave the Sudanese government up to 90 days to deliver on its commitments, the resolution cut the period by a third.
Abdul Wahab added that resolution concentrated on Khartoum and made little or no demands of the rebel groups that have been fighting the government for the past 17 months.
He argued this would send the "wrong signal to the rebels" and encourage them to stay away from negotiations.
The Sudanese cabinet will release its official reaction to the UN resolution on Sunday, he added.
In Addis Ababa, Sudan's ambassador to the African Union (AU), Osman Elsayed Fad Elsayed, said earlier Saturday: "Unlike Israel, which dumps UN resolutions, we are going to implement the resolution.
He said the government has dispatched a force of 6,000 police to Darfur to support the government force stationed there and to ensure security.
