President Vladimir Putin said on Tuesday that Russia could easily make and deploy land-based intermediate-range missiles if the United States made good on a threat to quit a landmark nuclear arms control treaty.

The United States has accused Russia of flouting the Intermediate-range Nuclear Forces Treaty signed by Washington and Moscow during the Cold War and has said it will quit it unless Russia comes back into compliance.

Putin on Tuesday denied his country was in violation of the agreement, but said it had developed powerful airborne and sea-based cruise missiles and could easily roll out land-based missiles if Washington walked away from the pact.

Tthere was nothing to stop Russia and the United States agreeing that other countries could join the Intermediate-range Nuclear Forces Treaty signed by Washington and Moscow during the Cold War.

The United States has accused Russia of flouting the nuclear pact, allegations Moscow denies, and has threatened to pull out. Other countries are able to develop missiles banned under the treaty because they are not signatories.

“What stops (us) starting talks on them joining the current agreement or starting to discuss parameters for a new accord?” Putin asked.
