The US has officially removed Sudan from its state sponsors of terror list.
President Donald Trump gave Congress the statutory 45-day notice of this move in October as part of a deal that involved Sudan paying $335m (£250m) to US victims of terror attacks.
At the same time Sudan agreed to normalise relations with Israel.
The US put Sudan on the list in 1993 after it was used as a base for al-Qaeda. Its removal should help with vital economic support measures.
The compensation relates to al-Qaeda’s 1998 bombing of the US embassies in Kenya and Tanzania in which more than 220 people died.
But the country was put on the US list after the first attack on the World Trade Center in New York in 1993, when Sudan hosted a number of Islamist militant groups as well as al-Qaeda leader Osama bin Laden.
The designation meant the US stopped Sudan from getting debt relief, and prevented the International Monetary Fund and other global institutions from lending the country money.
In the wake of the attacks in the US on 11 September 2001, Sudan’s security services helped the US Central Intelligence Agency.
But Sudan remained on the state sponsors of terrorism list, as some US politicians were concerned about human rights abuses and the war in Darfur.
There was subsequently a thaw in US-Sudan relations and most economic sanctions were lifted in 2017, but this did not improve the economy as anticipated.
In October, Sudan agreed to recognise Israel weeks after similar moves by the United Arab Emirates (UAE) and Bahrain.
Last week, Morocco became the latest Arab League country to agree to normalise relations with Israel.
The US still designates North Korea, Iran and Syria as state sponsors of terror.
‘A major win for Sudan’
Analysis by James Copnall, former BBC Sudan correspondent
The Sudanese authorities had been trying to get off the list for many years.
In private, and occasionally in public, US officials admitted the designation was a political tool, a point of leverage, rather than a fair assessment of whether Sudan was still supporting terror groups abroad.
The US would never have removed Sudan from the list as long as Bashir was in power; this has been made possible as a civilian cabinet is now in place.
The designation has been hugely damaging for Sudan.
The country was cut off from the global financial system. Now it can hope to re-engage with international financial institutions, obtain loans and get debt relief.
That sort of help is desperately needed, as the economy is in freefall, but it will probably be months or years before any impact is felt.
But the significance of getting off the list should not be downplayed. Sudan is no longer a pariah for the US and many others, and it should make a major difference to the economy in the years to come.
This is a major win for civilian Prime Minister Abdalla Hamdok and his government.
