BANGKOK -- A second summit between President Donald Trump and North Korean leader Kim Jong Un is set for Vietnam's capital from Feb. 27-28.

Trump and Kim met last June in Singapore, outreach the American president has said opened a path to peace. But that face-to-face hasn't resulted in any solid plan for ridding the North of nuclear weapons.

The Singapore summit made history by simply being the first-ever meeting between sitting leaders of the longtime enemies. It was filled with pageantry and memorable moments, such as the first handshake, walks in a garden, and a brief glimpse inside Trump's limousine.

This time, observers will be looking for something more concrete.
