Russia will follow nuclear arms ceiling if the US does, says Lavrov

However, Russia's limit on warheads applies only as long as the US acts similarly, Lavrov announced.

The agreements that, in various forms, have limited the nuclear warheads of the US and Russia since 1991 expired at the beginning of February. Under them, each side was allowed 1,550 nuclear warheads.

"We will make a better deal," US President Donald Trump told The New York Times in January, emphasizing that a new agreement should include China with its rapidly growing arsenal.
