On November 15, 1949 the United States, United Kingdom and France sent parallel notes to the governments of Bulgaria, Czechoslovakia, Hungary, Rumania, the Soviet Union and Yugoslavia declaring that the United States, United Kingdom and France did not recognize the Convention of August 18, 1948, establishing the Danube Commission, as having any valid international effect. Declaring that the convention violated concepts of international waterways which had been recognized in Europe for 130 years, the note stated that it also failed to carry out the decision of the Council of Foreign Ministers of December 6, 1946. The convention deprived the United Kingdom and France of rights established by international agreement in 1921, and disregarded the “legitimate interest of non-riparian states.”
