The Russian Foreign Ministry says it will not allow the use of its territory for nuclear tests. The Russian government has refused to allow nuclear tests in the Russian part of the Caspian Sea.
The move is seen as a violation of a bilateral agreement between Russia and the West on nuclear testing in the region of Caspia. The Caspians are the only region of the world where nuclear testing is allowed. The U.S. government has also refused to participate in any nuclear tests, saying it is not in line with the CSPO agreement.
