The Sudan government has agreed to pay United States of America $335 million for the victims of the US embassy attacks in East African Cities: Nairobi and Dar es Salaam (1998 which killed dozens of people)

US has listed Sudan for years as one of the countries sponsoring terrorism around the world.
Currently, it looks like Sudan is buying her freedom and is ready to pay for the damages.

Both USA and Sudan have been building bridges and improving their diplomatic ties. But the move by USA to pressure Sudan to pay the amount is seen by critics as a bullying case or perhaps Sudan is buying for her freedom.
Sudan has been over sanctions by United States which has affected its economy leading to fall of Omar Bashir last year.
