In his message to Party General Secretary and State President Nguyen Phu Trong, the DPRK leader affirmed his resolve to develop the relationship between the two countries.
The friendly relations, founded by DPRK leader Kim Il-sung and Vietnamese President Ho Chi Minh, have been steadily developed in the joint struggle for the socialist cause for the past 70 years, the Korean Central News Agency (KCNA) quoted his message as highlighting.
Kim also expressed his belief that the relations between the two countries would continue to develop in depth in the spirit of the agreement they reached during a meeting in Hanoi in March last year.
He is the first DPRK leader to pay an official visit to Vietnam over the past 55 years. His predecessor Kim Il-sung visited the Southeast Asian nation in 1958 and 1964.
