During the 2000 inter-Korean summit, North Korean leader Kim Jong-il made a gift of two Pungsan dogs (associated with the North) to South Korean president Kim Dae-jung. In return, Kim Dae-jung gave two Jindo dogs (associated with the South) to Kim Jong-il. Born at the Pyongyang Central Zoo, the Pungsan dogs were originally named Dangyol (Unity) and Jaju (Independence), but were later renamed Uri (meaning We) and Duri (Two). They initially lived in the Blue House, the residence of the South Korean president, before being moved to the Seoul Zoo, where they gave birth to 15 puppies before both dying at age 13. During their lives, the dogs were accorded special status as guests of the state.
