Seoul Surges: 10 Must-See Reasons the World Can’t Stop Buzzing About South Korea’s Capital in 2026

Seoul is once again at the center of fast-moving geopolitics after U.S. President Donald Trump ordered American forces to scale back joint military drills with South Korea, a move that Seoul officials say is meant to push the Yoon administration to line up behind Washington’s pressure campaign on Iran and to accelerate a delayed $350 billion investment package in the United States. Foreign Minister Cho Hyun told lawmakers on Wednesday that the Pentagon’s abrupt cut—from eleven days of field exercises to just five—“contains several layers of pressure,” ranging from Iran policy to the yet-to-be-finalized list of U.S. infrastructure and clean-tech projects that Korean conglomerates are expected to bankroll. The timing is delicate for Seoul. August already brings heightened security sensitivity as the city marks Liberation Day and hosts the annual Ulchi Freedom Shield drills, which Pyongyang routinely denounces. Analysts warn that shrinking the exercises could embolden North Korea just as Kim Jong Un signals interest in another summit, and could also test the credibility of Washington’s “extended deterrence” pledge to defend the South. Economic stakes are equally high. Hyundai, Samsung SDI and SK On are weighing whether to expand their EV-battery footprints in Georgia and Michigan, while chipmaker SK Hynix is reconsidering a planned Ohio fab amid fears of a looming 15 % U.S. tariff on Korean steel that would raise construction costs. “Companies cannot finalize board decisions until tariff clarity emerges,” said Park Soo-jin, chief economist at the Korea International Trade Association. For President Yoon, domestic pressure is intensifying. Opposition lawmakers argue that paying billions for U.S. factories while Washington trims alliance activities is politically untenable. Labor unions, already staging street rallies over Seoul’s record heatwave, plan to merge economic grievances with anti-war protests outside the U.S. Embassy this weekend. Still, some observers see opportunity. “If Seoul uses the leverage of investments wisely, it can secure exemptions on tariffs and lock in technology cooperation that would future-proof its semiconductor sector,” noted Kim Eun-ho of the Asan Institute. Diplomatic sources say quiet talks are underway for a Yoon-Trump phone call that could reset the tone before the United Nations General Assembly next month. Meanwhile, city hall is trying to keep business confidence intact. Mayor Oh Se-hoon unveiled an accelerated “Nighttime Economy” pilot along the Han River to entice tourists and offset any chill in foreign direct investment, pledging tax breaks for hospitality startups that open before year-end. With Washington pushing hard, Pyongyang watching closely and Wall Street evaluating every headline, the clock is ticking for Seoul to balance security assurances with industrial policy—without losing its footing in a summer already defined by record temperatures and global market volatility.
