France and Britain are working to unfreeze Libyan assets blocked by UN Security Council sanctions.
Foreign Secretary William Hague said that Britain was "engaged at the United Nations and elsewhere to pave the way for the unfreezing of assets."
France also confirmed it was seeking a UN resolution to do so.
The two countries want to unfreeze billions of dollars in Libyan assets as quickly as possible to help rebuild the economy, restore essential services, reform the police and the army, and help the rebels form a government after they overthrow Muammar Qaddafi.
"As a tyrant in Libya, Muammar Qaddafi used the resources of his country to perpetrate horrible terrorist acts against Americans and people around the world," White House deputy spokesman Josh Earnest said on August 24.
"So I think there is a pretty tangible interest that we have in supporting the Libyan people as they put in place the kind of government that will support freedom, that will support democracy, that will allow them to be a constructive member of the international community."
The UN Security Council froze Libyan assets after Qaddafi cracked down on protests in February.
