Russia calls US for addressing mutual grievances amid concerns over arms treaty

Russia is ready to work on addressing mutual grievances with the way that the Intermediate-Range Nuclear Forces Treaty is being implemented, a senior security adviser to President Vladimir Putin said on Monday.

Nikolai Patrushev, Secretary of Russia's Security Council, was quoted as making the comments by Russian news agencies after a meeting in Moscow with John Bolton, U.S. President Donald Trump's national security advisor.

Patrushev was also quoted as saying that he and Bolton had discussed extending the New START arms control treaty, which is due to expire in 2021, by a further five years. He did not say if any agreement was reached.
