On July 31, 1979, the 394th meeting of the Military Armistice Commission was held to address a North Korean armed spy boat which infiltrated the coastal waters of Samcheonpo at the southernmost tip of the Korean Peninsula. At the time, UN Command protested that the infiltration of the spy boat around the Samcheonpo coast constituted a breach of the Armistice Agreement, presenting various weapons dredged up from the boat as evidence.
