WASHINGTON -- U.S. Secretary of State Hillary Clinton and Ukrainian Foreign Minister Kostiantyn Hryshchenko have signed a memorandum of understanding on nuclear security cooperation between the United States and Ukraine.
The agreement was signed on September 26 in New York City.
The document caps an agreement reached by U.S. President Barack Obama and Ukrainian President Viktor Yanukovych at the 2010 Nuclear Security Summit to work together on nonproliferation efforts.
Ukraine has already given up a considerable amount of its highly enriched uranium and has pledged get rid of the rest of its stocks by March 2012, when the next Nuclear Security Summit will take place.
In exchange for giving up the enriched uranium, Washington is providing Ukraine with financial and technical assistance for the elimination process and helping to modernize Ukraine's civil nuclear research facilities.
Enriched uranium is used in Ukraine's research and medical institutes.
