Canada’s brief participation in the International Commission for Control and Supervision (ICCS) in Vietnam, from the end of January to July 31, 1973, ended her active role as a supervisory power for maintaining peace in Indo-China, although it did not imply an abandonment of her traditional policy of working in the interests of international stability and coexistence.
Canada was a natural choice for the new peace-keeping machinery by virtue of her 19-year experience in the three International Control Commissions (ICC), even though she had taken no part in the protracted secret negotiations that led to the Agreement on Ending the War and Restoring Peace in Vietnam signed on January 27, 1973, by the United States, the Democratie Republic of Vietnam, the Republic of Vietnam, and the Provisional Revolutionary Government of the Republic of South Vietnam. The American Secretary of State, Mr. William P. Rogers, and the Canadian Minister for External Affairs, Mr. Mitchell Sharp, therefore consulted as early as October 25 and subsequently on November 20, 1972, to consider Canada’s possible participation, with Indonesia, Hungary, and Poland, in a new agency to be known as ICCS.
