 The OSTK had only a tenuous hold, however, on the city government of Dubasari and was a minority in some of the more rural districts.Throughout 1990, OSTK-controlled soviets in Transnistria battled with republican authorities in Chişinău, many of the latter also elected in 1990 and that on a platform of national awakening.On 27 April 1990, the Supreme Soviet of Moldova took the symbolic step of adopting a new republican flag based on the yellow, red and blue Romanian flag.
