WASHINGTON — For the first time, the United States may be willing to accept a United Nations condemnation of the U.S. trade embargo against Cuba without a fight, The Associated Press has learned.

U.S. officials tell the AP that the Obama administration is weighing abstaining from the annual U.N. General Assembly vote on a Cuban-backed resolution demanding that the embargo be lifted. The vote could come next month.

No decision has yet been made, said four administration officials who weren’t authorized to speak publicly on sensitive internal deliberations and demanded anonymity. But merely considering an abstention is unprecedented. Following through on the idea would send shock waves through both the United Nations and Congress.

It is unheard of for a U.N. member state not to oppose resolutions critical of its own laws.

And by not actively opposing the resolution, the administration would be effectively siding with the world body against Congress, which has refused to repeal the embargo despite calls from President Barack Obama to do so.
