At a meeting in Paris in September 1948 the ministers failed to agree on what to do with the former Italian colonies. The council was revived in 1949 and met in Paris, during May and June, where they agreed to the ending of the Soviet blockade of Berlin, but failed to agree on German reunification. The Berlin meeting in 1954 ended in deadlock, but the following year in Vienna, they agreed on a peace treaty for Austria (the Austrian State Treaty).
