The 1987 Intermediate-Range Nuclear Forces Treaty (INF) prohibits the use or development of ground-launched cruise missiles within the range of 300 to 3,400 miles. US authorities have recently accused Russia of failing to live up to its side of the deal.
"US claims have been discussed at various levels many times, but we have not been able to settle the dispute due to US’s inability to meet us halfway or present us with crucial data on the essence of its claims," Deputy Foreign Minister Sergei Ryabkov said at a parliamentary hearing.
US Deputy Assistant Secretary of Defense responsible for Eurasia, Michael Carpenter, said in April that the Unites States had indisputable evidence that Russia was violating the INF deal. Moscow has repeatedly denied this allegation.
