Russia said on Thursday the U.S. had shown it was not willing to address Moscow’s main security concerns, set out during their standof over Ukraine, but that both sides had an interest in continuing dialogue. Kremlin spokesman Dmitry Peskov said Moscow, which has massed troops near Ukraine, would not rush to draw conclusions after Washington formally responded to Russian proposals for are drawing of post-Cold War security arrangements in Europe. Describing tensions on the continent as reminiscent of the Cold War, Mr. Peskov said it would take time for Moscow to review Wednesday’s response from Washington. But he said U.S. and NATO statements that Russia’s main demands were unacceptable did not leave much room for optimism. “Based on what our colleagues said yesterday, it’s absolutely clear that on the main categories outlined in those draft documents… we cannot say that our thoughts have been taken into account or that a willingness has been shown to take our concerns into account,” Mr. Peskov said. “But we won’t rush with our assessments,” he said. Nuanced reaction The nuanced Kremlin reaction made clear that Russia, which has massed tens of thousands of troops close to its border with Ukraine, is not rejecting the U.S. and NATO responses out of hand or closing the door to diplomacy. Russian and Ukrainian dollar bonds, which have been hammered in recent weeks by the mounting tension, both rose in response to Mr. Peskov’s comments. Russian Foreign Minister Sergei Lavrov said there was hope of starting serious dialogue, but only on secondary questions and not on the fundamental ones, Russian news agencies reported. The U.S. and NATO said on Wednesday they had delivered the written responses requested by Moscow to proposals it submitted in December. Among other things, it demanded that NATO halt any further enlargement, bar Ukraine from ever joining the alliance and pull back forces and weaponry from eastern European countries that joined it after the Cold War ended.
