Egypt abrogated the Anglo-Egyptian Treaty of 1936, began restricting Israeli shipping, and in 1955 turned to Czechoslovakia to purchase weapons. In July 1956 the United States withdrew financial assistance for Egypt's Aswan Dam project, leading Egypt to nationalize the Suez Canal Company. In September, the Security Council convened to consider "the situation created by the unilateral action of the Egyptian government in bringing to an end the system of international operation of the Suez Canal" and "actions against Egypt by some Powers, particularly France and the United Kingdom, which constitute a danger to international peace and security and are serious violations of the Charter of the United Nations".[1]
