Should the referendum pass, U.S. and European leaders have said they may impose further restrictions on Russia, including possible economic sanctions and travel bans on Russian officials and military officers. The EU foreign ministers are scheduled to meet on Monday, March 17 to discuss the situation. In another potential escalation of the Ukraine situation, Russian media reports published March 9 suggested that Russia may be prepared to suspend receiving inspection teams as required under the 2010 New START Treaty because of "groundless threats to Russia from the U.S. and NATO regarding its Ukrainian policy are considered by us as an unfriendly gesture and allow to declare force majuere." According to the Part Five, Section IX of the Protocol of the New START Treaty, the only basis for the cancellation of inspections are "circumstances brought about by force majuere," which is an event that is a result of the elements of nature, as opposed to one caused by human behavior. According to March 14 an email from a senior official with the Russian Ministry of Foreign Affairs to the Arms Control Association, March 14, Russia intends to fully comply with it's commitments under current arms control agreements between the two countries. He referred to a March 12 statement by Deputy Defense Minister Anatoly Antonov, who told reporters on Wednesday: "We intend to continue to fulfill [our] international obligations and to continue the practice of voluntary transparency in the extent to which it will respond to our interests. [Of] course, this applies fully to the START Treaty and the Vienna Document [of] 2011."
