Polish–Romanian relations are foreign relations between Poland and Romania. Both countries established diplomatic relations on February 9, 1919, with Poland being the first nation to recognize Romania's claims to Transylvania. In recent years government representatives of Poland and Romania regularly exchange high-level visits, a reflection of the mutual interest in bilateral cooperation between the two countries. The Warsaw Institute, a Polish think tank, maintains a Romania Monitor to explain the main course of political, economical and social developments in Romania and Moldova.
