MOSCOW (Reuters) - Russia further curtailed its cooperation with the United States in nuclear energy on Wednesday, suspending a research agreement and terminating one on uranium conversion, two days after the Kremlin shelved a plutonium pact with Washington.

The Russian government said that as counter-measures to the U.S. sanctions imposed on Russia over Ukraine, it was putting aside a nuclear and energy-related research pact with the United States.
