Air Force One touched down at Osan Air Base, an American military installation outside the capital Seoul, at 5:22 p.m. local time (4:22 a.m. ET) after a lengthy journey from Washington. Immediately after his arrival, Biden is planning to visit a Samsung semiconductor factory to emphasize the importance of strengthening American supply chains, which have been reliant on Chinese materials.
The stakes of Biden's trip have been ratcheted higher by the threat of a nuclear or missile test from North Korea. The prospect looms over Biden's stop in Seoul, where he was planning to tout economic partnership and security ties alongside the country's newly elected President.
