Moon and other officials watched the live broadcast of the summit before a South Korean Cabinet meeting in his presidential office today.
Moon has met Kim twice in recent months and helped arrange the U.S.-North Korean summit.
Moon said he "ardently aspires" for the success of the summit and hopes it brings complete denuclearization and peace to the Korean Peninsula.
Fighting in the Korean War ended with an armistice in July 1953. That armistice has yet to be replaced with a peace treaty, leaving the peninsula in a technical state of war.
