The growing confrontation between Washington and Moscow over Ukraine has derailed a recent accord that promised one of the most expansive collaborations ever between the countries' nuclear scientists, the New York Times reported.
"It was only 11 months ago that the American energy secretary - Ernest J. Moniz, a former M.I.T. professor who has championed scientific programs that would bury the Cold War competitions between the United States and Russia - went to Vienna to sign the agreement, an indication of how recently the Obama administration believed it had a chance of building on a quarter-century of gradual integration of Russia with the West,"- the newspaper wrote.
Daniel B. Poneman, the deputy energy secretary, said that Russia's annexation of Crimea in March had prompted the decision to freeze the accord.
"We've made it very clear that this is not a time for business as usual,"- he said.
