NO South Korea did not sign the armistice in 1953, therefore North and South Korea are still at war.
July 27, 1953 The United States, North Korea and China sign an armistice, which ends the war but fails to bring about a permanent peace. To date, the Republic of Korea (South) and Democratic Peoples' Republic of Korea (North) have not signed a peace treaty. North and South Korea did sign a non-aggression treaty in 1991.
