SEOUL, SOUTH KOREA—President Barak Obama has handed over nine ancient royal seals to South Korea President Park Geun-hye. The seals were carried to the United States by an American Marine who served in the Korean War. “I wanted to just let the Korean people know that they’re back where they belong,” President Obama told USA Today. “After his passing, his widow discovered how important they were, and she graciously recognized that they appropriately belonged here in Korea,” he added.
