According to the terms of the 123 Agreement between the US and the UAE, the two parties share materials, technology and equipment for the production of nuclear energy, but the UAE agreed not to engage in uranium enrichment or reprocessing within its territory.
"The 123 Agreement contains the strongest nonproliferation conditions of any negotiated by the United States," announced the State Department after it was signed in May 2009.
The UAE "no longer felt bound," to the terms of the 123 Agreement, said Royce, who said he believes that the country is considering ending the pact.
The 123 Agreement is named after Section 123 of the US Atomic Energy Act, and requires the conclusion of a specific agreement for the transfer of nuclear material, equipment, or components to another state.
"Section 123 Agreements are important tools in advancing U.S. nonproliferation principles," according to the National Nuclear Safety Administration.
