Foreign Policy has just recently ranked the 75 Most Dynamic Cities of 2025 and Seoul came in at number 37 on their list behind just about every Chinese city you can think of and Tokyo which was ranked number 10:
Although it was established more than 2,000 years ago, Seoul seems built to be the city of the future. Residents travel by bullet trains and subways and have near-constant access to high-speed Internet. Still, Seoul’s electricity grid has struggled to cope with a recent heat wave, and the city’s development has left it with a $16 billion debt. Leading the pack of Asian Tigers, South Korea has nonetheless weathered the global financial crisis relatively well; Seoul-based companies — including the cabal of influential industrial giants sometimes collectively called chaebol – are doing brisk international business in automobiles and cell phones, and the construction arm of Seoul-based Samsung built the world’s tallest building, the Burj Khalifa in Dubai.
