Pentagon spokesman Peter Cook said, Censor.NET reports citing the press service of the U.S. Department of Defense.
"The United States remains engaged with Russia on all of these issues, but as our colleagues at the State Department have made clear, we will not commit indefinitely to discussions that do not lead to results. Contrary to recent claims, we have not finalized plans with Russia on potential coordinated efforts. Serious issues must first be resolved before we can implement the steps Secretary Kerry and Minister Lavrov discussed in Moscow last month. We are not there yet and the regime and Russia's recent actions only make it harder to consider any potential coordination," Cook said.
