Knowledge of Korean history and culture is essential for U.S. businesses hoping to succeed in the country. 

Korean history is characterized by a series of rich dynasties and conquests by neighboring East Asian countries, particularly Japan and China. In 1910, Japan annexed Korea and established a 35-year-long period of colonial rule lasting until the surrender of Japan at the end of World War II. Following Japan’s surrender in 1945, the Korean Peninsula was divided at the 38th parallel into two occupation zones, with the U.S. in the South and the Soviet Union in the North. Despite initial hopes for reunification, the northern Democratic People’s Republic of Korea and Republic of Korea in the south soon became engulfed in a civil war (1950-1953), and the Peninsula has remained divided since.  Efforts to improve relations between Korea and Japan culminated in the August 2023 trilateral summit at Camp David where the three countries committed to deepening cooperation on a broad range of security and economic initiatives.

Following the Korean War, Korea was one of the poorest countries in the world. However, due to the expertise of chaebols (conglomerates) and the development of heavy industry, Korea was able to achieve significant growth and transform into what is now one of the world’s largest modern economies. 

Today, Korea boasts significant strengths across multiple industries. While Korea’s historic heavy industries remain strong, the country is now known for being home to world-acclaimed electronic appliances, award-winning cars, healthcare, and smartphones. Korean popular culture, including idol bands and television dramas, has captured the hearts of fans worldwide in a phenomenon known as Hallyu, or the “Korean Wave.” Korea has also hosted numerous global events such as the Summer Olympics (1988), the Soccer World Cup (2002; along with Japan), the G-20 Leaders Summit (2010), and the 2018 Winter Olympics in Pyeongchang.  These major events, a source of pride and accomplishment, have intensified Korea’s push to have a first-rate infrastructure, hospitality, and transportation system.

Seoul, the capital of Korea, is a lively cosmopolitan city. The city is divided by the Han River, which is spanned by 27 bridges. Most international flights arrive at Incheon Airport, which is located about one hour from the city center. Traffic congestion, a persistent problem in Seoul, must be factored into arriving on time for business appointments. Punctuality is critical when conducting business in Korea, so you should plan to arrive at least 20 minutes early to any meetings or appointments.

Other important business success factoids:

  • Last names and titles: Always use Mr., Mrs., or any title (like Director) followed by the last name. Also appropriate is: Mr. LEE (last name, followed by the first name) Ji-hoon (two syllables of the first name); in this order. 
  • Business cards: Your business cards say a lot about you and your business and are extremely important in Asian and Korean cultures. Hand them out using both hands (thumbs at the top corners of your card) while giving a gentle and slight bow, and avoiding too much direct eye contact. Never put a newly received business card away or in your back pocket. Rather, look at it for a moment and place it on the desk or table where you are meeting. Bilingual cards are best.
  • Handshakes: Unlike the firm Western-style handshake, Korean handshakes are typically gentler.
  • Cold calls are generally unacceptable and seen as culturally inappropriate and disrespectful.
  • Negotiating: A rigid negotiating style does not work in Korea. Koreans interpret contracts as loosely structured consensus statements, broadly defining what has been negotiated/discussed, but leaving room to permit flexibility and adjustment. Koreans are subtle and effective negotiators. See Chapter 3 of this guide for additional insights into negotiating.
  • Two phrases that you should know in Korean are: 
  • Ann-yong-ha-sayo – Hello.
  • Gam-sa-ham-nida – Thank you.
