International Sales.
Belatedly just noted an earlier comment that Koreans would have no scrupples while negotiating a purchase. I beg to differ. Some years ago, I sold some jetliners to a major Korean Airline. During the negotiations, they wouldn't even go to lunch with us and addressing each other was very formal. After the deal was signed, the jackets came off, we became bosom buddies and taken out for a traditional Korean meal to celebrate.
