US Treasury Secretary Steven Mnuchin signed on Wednesday an agreement giving Sudan access to more than $1 billion, during a one-day visit to Khartoum, the government said.

Sudan's acting finance minister Hiba Ahmed and Mnuchin "signed a memorandum of understanding in Khartoum to provide a same-day bridge financing facility to clear Sudan's arrears to the World Bank," her office said in a statement.

"This move will enable Sudan to regain access to over $1 billion in annual financing from the World Bank for the first time in 27 years."
