Ukrainian Ambassador to the Republic of Poland \/ former minister of foreign affairs Andrii Deshchytsia states that Russian Minister of Foreign Affairs Sergey Lavrov refused to communicate with Ukrainian authorities in the period from February 22 to April 4, 2014. Deshchytsia testified this at the Obolonskyi District Court of Kyiv where he was invited as a witness under the high treason case of former president Viktor Yanukovych, Ukrainian News Agency reports. In particular, Deshchytsia testified that he made several attempts in February and March of 2014 to establish contact with Lavrov but the latter downrightly refused to communicate with new Ukrainian leadership claiming it was illegitimate. According to Deshchytsia, in the course of diplomatic communication, Lavrov denied presence of Russian military in Crimea. In addition, Deshchytsia stated that the letter by Yanukovych to Russian President Vladimir Putin asking to deploy troops to Ukraine was exploited by the Russian Federation for legitimization of its military actions. As Ukrainian News Agency earlier reported, on Wednesday, the court started taking witness statements from Deshchytsia under the high treason case of former president Yanukovych.
