Visa and entry
- China: 30 days visa-free for 38+ countries; 240-hour transit for 55 more. Effectively zero friction for Western passport holders in 2026.
- Korea: 90 days visa-free for most Western passports, but requires K-ETA ($10, applied online 72 hrs ahead). Easier than a visa, but still a step.
Ease on the ground
- English signage: Korea wins. Subway and street signs are fully bilingual; staff in Seoul speak more English than in any tier-1 Chinese city.
- Payments: Korea takes Visa/Mastercard everywhere. China requires Alipay or WeChat Pay setup, but once done it's frictionless.
- Internet: Korea is fully open. China requires a travel eSIM to bypass the firewall.
What each country is for
- Pick Korea for: K-pop, Korean BBQ, palaces, hiking near Seoul, a one-week trip with minimal planning.
- Pick China for: The Great Wall, Shanghai's skyline, Sichuan food, HSR road-trips, Tibet/Yunnan/Xinjiang adventures, half the price.
Do both
Seoul to Shanghai is 90 minutes by air for $150 round trip. A 7-day Korea + 7-day China itinerary works beautifully — and the 240-hour transit visa means you don't even need a Chinese visa for the second half.
