 While Russian troops from Moldova proper and from the security zone were evacuated to Russia by January 1993, Russia continued to have a significant military presence in Transnistria.On 21 October 1994, Russia and Moldova signed an agreement that committed Russia to withdrawal of the troops in three years, which however did not come into effect because only Moldova ratified it.Moldovan diplomacy took advantage of the negotiations concerning The Adaptation of the Treaty on Conventional Armed Forces in Europe (CAF), and managed to ensure that a special paragraph about the removal of Russian troops from Moldova's territory was introduced into the text of the OSCE Summit Declaration of Istanbul (1999), through which Russia had committed itself to pulling out its troops from Transnistria by the end of 2002.
