Russian Defense Minister Sergei Ivanov on Thursday threatened retaliatory steps if any country deploys weapons in space, Russian news agencies.
"Russia's position on this question has not changed for decades: We are categorically against the militarization of space," Ivanov said, according to the Interfax news agency.
"If some state begins to realize such plans, then we doubtless will take adequate retaliatory measures," ITAR-Tass quoted him as saying at the Baikonur cosmodrome in Kazakhstan.
The U.S. administration currently is reviewing the U.S. space policy doctrine. Last month, White House spokesman Scott McClellan told reporters that the policy review was not considering the weaponization of space. But he said new threats to U.S. satellites have emerged in the years since the U.S. space doctrine was last reviewed in 1996, and those satellites must be protected.
In 2002, after the United States withdrew from the 1972 Anti-Ballistic Missile Treaty, China and Russia submitted a proposal for a new international treaty to ban weapons in outer space.
But the United States has said it sees no need for any new space arms control agreements. It is party to the 1967 Outer Space Treaty, which prohibits stationing weapons of mass destruction in space.
Germany continues the discussion about the completion and commissioning of the Nord Stream 2 gas pipeline. For the time being, it is too early to ascertain that the opponents of the project are gaining the upper hand
