Central Europe and, more recently, the Baltic states. During the 2004 Ukrainian presidential election, Putin twice visited Ukraine before the election to show his support for Ukrainian Prime Minister Viktor Yanukovych, who was widely seen as a pro-Kremlin candidate, and he congratulated him on his anticipated victory before the official election returns had been in. Putin's personal support for Yanukovych was criticized as unwarranted interference in the affairs of a sovereign state (See also The Orange revolution). Crises also developed in Russia's relations with Georgia and Moldova, both former Soviet republics accusing Moscow of supporting separatist entities in their territories. Russia's relations with the Baltic states remain tense. In 2007, Russo-Estonian relations deteriorated further as a result of the Bronze Soldier of Tallin controversy. Putin took an active personal part in promoting the Act of Canonical Communion with the Moscow Patriarchate signed 17 May 2007, which restored relations between the Moscow-based Russian Orthodox Church and Russian Orthodox Church outside Russia after the 80-year schism. In his annual address to the Federal Assembly on 26 April 2007, Putin announced plans to declare a moratorium on the observance of the Treaty on Conventional Armed Forces in Europe by Russia until all NATO members ratified it and started observing its provisions, as Russia had been doing on a unilateral basis. Putin argues that as new NATO members have not even signed the treaty so far, an imbalance in the presence of NATO and Russian armed forces in Europe creates a real threat, and an unpredictable situation for Russia. NATO members said they would refuse to ratify the treaty, until Russia complied with its 1999 commitments made in Istanbul, whereby Russia should remove troops and military equipment from Moldova and Georgia. Russian Foreign Minister, Sergey Lavrov, was quoted as saying in response that "Russia has long since fulfilled all its Istanbul obligations relevant to CFE". Russia has suspended its participation in the CFE as of midnight Moscow time on 11 December 2007. On 12 December 2007, the United States officially stated that it "deeply regretted the Russian Federation's decision to 'suspend' implementation of its obligations under the Treaty on Conventional Armed Forces in Europe (CFE)." State Department spokesman Sean McCormack, in a written statement, added that "Russia's conventional forces are the largest on the European continent, and its unilateral action damages this successful arms control regime." NATO's primary concern arising from Russia's suspension is
