MOSCOW, October 5. /TASS/. Russian Prime Minister Dmitry Medvedev has signed a decree on suspending an agreement between Russia and the US on cooperation in research and development in the nuclear and energy sectors. The relevant document has been posted on the Cabinet website on Wednesday.

"In connection with the imposition of restrictions on cooperation with the Russian Federation in nuclear energy by the United States of America … to suspend the agreement between the government of the Russian Federation and the government of the United States of America on cooperation in research and development in the nuclear and energy sectors of September 16, 2013," the decree says.

Under this decree, the Russian Foreign Ministry has been instructed to send a written notification of the agreement’s suspension to the US.

An explanatory note to the document points out that "the actions taken by the US in connection with imposing sanctions against Russia have directly affected the areas of cooperation envisaged by the agreement."

"The regular extension of anti-Russian sanctions by the US, which include the suspension of the Russian-US cooperation in nuclear energy, requires countermeasures against the American side," the explanatory note says. It also notes that Moscow will retain an opportunity to resume cooperation under this agreement when this is justified from the point of view of the general context of relations with the US."

On October 3, Russian President Vladimir Putin ordered to suspend cooperation with the US on plutonium disposal because of Washington’s unfriendly actions towards Russia.
