As UNIAN reported earlier, the in a decree published on Monday, October 3, Russia froze an agreement to dispose of surplus plutonium because of “a drastic change in circumstances, the appearance of a threat to strategic stability due to unfriendly actions of the United States toward Russia.”

The Plutonium Management and Disposition Agreement (PMDA) was an arrangement for reprocessing weapons-grade material into fuel for nuclear reactors. The deal, first negotiated by Vladimir Putin and Bill Clinton in 2000 and updated in 2010, committed both countries to disposing of at least 34 tonnes of bomb-grade plutonium, enough to produce around 17,000 nuclear weapons.
