HO CHI MINH CITY, Vietnam (AP) — President Barack Obama is completing a three-day trip to Vietnam with a town hall Wednesday involving about 800 young adults participating in efforts to strengthen ties between the United States and Southeast Asia.

Obama often incorporates a question-and-answer session with young leaders into his foreign trips. He is meeting with participants in the Young Southeast Asian Leaders Initiative. The initiative targets adults under the age of 35 in a variety of educational and cultural exchanges.

After the event, Obama is scheduled to fly to Japan as part of a trip that will include the first visit to Hiroshima since the end of World War II by a sitting U.S. president.

Obama also planned to meet later Wednesday with Japanese Prime Minister Shinzo Abe (shin-zoh ah-bay).
