Pe Khin was a Burmese diplomat. He was one of the main negotiators at the second Panglong Conference, held in February 1947 by General Aung San (head of the interim Burmese government) and Shan, Kachin and Chin ethnic minority leaders. Pe Khin was the primary architect of the resulting Panglong Agreement, which laid out plans for a united struggle against the British and the future of Burma after independence. This historic document would eventually lead to the establishment of the Union of Burma, which became an independent nation on January 4, 1948. Pe Khin was appointed as Burma's first Ambassador to Pakistan in 1947. He was then Ambassador to Thailand from 1953 to 1956. He was transferred to the Soviet Union in 1964, and to Singapore in 1966. He retired from diplomatic service in 1972.
