North Korean leader Kim Jong-un exchanged letters with South Korea's outgoing President Moon Jae-in earlier this week in an "expression of their deep trust," state media reported Friday.
Kim received a "personal" letter from the Moon, on Wednesday, and sent a reply letter the next day, according to the North's official Korean Central News Agency (KCNA).
"Sharing the same view that the inter-Korean relations would improve and develop as desired and anticipated by the nation if the North and the South make tireless efforts with hope, the top leaders mutually extended warm greetings to the compatriots in the North and the South," KCNA reported.
In his letter, Moon, whose five-year term is set to end on May 9, stressed his continuing support for the foundation for reunification between the two Koreans even after his retirement, as Kim appreciated what the president has done for the "great cause of the nation," according to the KCNA.
"The exchange of the personal letters between the top leaders of the North and the South is an expression of their deep trust," it added.
Shortly after the KCNA's report, Moon's office confirmed that the two leaders had exchanged letters.
