Hanoi: As North Korean leader Kim Jong-un continued with official engagements in Hanoi, despite the collapse of his summit with Donald Trump, Vietnam's President and Prime Minister weren't the only ones on his schedule.

The Vietnam-Korea Friendship Kindergarten is a relic of the once-close ties between Vietnam and North Korea in the aftermath of the war with the United States. It opened in 1978 with funding from North Korean founder Kim Il-sung.

Its classrooms are named after North Korean leaders. Portraits of Kim Il-sung and Kim Jong-il gaze down from the walls.
