Seoul Business Pulse
- Culture Extremely hardworking and hierarchical. "Pali-pali" (hurry-hurry) culture drives rapid growth.
- Lunch Break 12:00 PM - 1:00 PM.
- Pro Tip The ideal window is 9:30 AM to 11:30 AM. South Koreans value speed ("Pali-pali") and expect rapid responses. Avoid the 12-1 PM lunch hour strictly. Ensure you follow hierarchical protocols if senior leaders are present, and never arrive (digitally or in-person) late for a call.
Ulaanbaatar Business Pulse
- Culture Resilient, pragmatic, and values relationship building. Influenced by its unique history and climate.
- Lunch Break 1:00 PM - 2:00 PM.
- Pro Tip Reach out between 10:00 AM and 12:00 PM. Mongolian business culture is relational; personal trust must be built through multiple interactions. Be direct but also patient and polite. Personal presence is highly valued. In winter, be mindful that local schedules may be slightly affected by extreme cold.
