The absence of a Russian ambassador in Kiev means that bilateral relations have been frozen, Ukrainian President Viktor Yushchenko was quoted as saying in an interview with a Polish paper on Tuesday. In an Aug. 11 open letter to Yushchenko, Russian President Dmitry Medvedev announced that he was holding off sending Russia's new ambassador to Ukraine over Kiev'ies anti-Russian policies. "The absence of the [Russian] ambassador means a freeze in relations," he said in an interview.
