The NATO summit held in Warsaw in July 2016 approved the plan to move four battalions totaling 3,000 to 4,000 troops on a rotating basis by early 2017 into the Baltic states and eastern Poland and increase air and sea patrols to reassure allies who were once part of the Soviet bloc. The adopted Communique explained that the decision was meant "to unambiguously demonstrate, as part of our overall posture, Allies' solidarity, determination, and ability to act by triggering an immediate Allied response to any aggression." The summit reaffirmed NATO's previously taken decision to "suspend all practical civilian and military cooperation between NATO and Russia, while remaining open to political dialogue with Russia". Heads of State and Government "condemned Russia's ongoing and wide-ranging military build-up" in Crimea and expressed concern over "Russia's efforts and stated plans for further military build-up in the Black Sea region". They also stated that Russia's "significant military presence and support for the regime in Syria", and its military build-up in the Eastern Mediterranean "posed further risks and challenges for the security of Allies and others". NATO leaders agreed to step up support for Ukraine: in a meeting of the NATO-Ukraine Commission, the Allied leaders reviewed the security situation with president of Ukraine Poroshenko, welcomed the government's plans for reform, and endorsed a Comprehensive Assistance Package for Ukraine aimed to "help make Ukraine's defence and security institutions more effective, efficient and accountable". At the meeting of the Russia–NATO Council at the level of permanent representatives that was held shortly after the Warsaw summit, Russia admonished NATO against intensifying its military activity in the Black Sea. Russia also said it agreed to have its military aircraft pilots flying over the Baltic region turn on the cockpit transmitters, known as transponders, if NATO planes acted likewise.
