Much work—and some play—on a U.S. study tour for 15 mid-career Asian diplomats.

Ms. Sujana Aryal is a protocol officer in the Ministry of Foreign Affairs of Nepal, and Mr. Nguyen Dong Anh is vice-dean of faculty at the International Communications-and-Culture Diplomatic Academy of Vietnam’s Ministry of Foreign Affairs.
