North Korean leader Kim Jong-un has visited cemeteries to pay respects to the country's soldiers killed during the 1950-53 Korean War and to commemorate the anniversary of the signing of the armistice, state media said Wednesday.

The Korean War ended with an armistice agreement on July 27, 1953. The North calls the war the Great Fatherland Liberation War and designated the armistice signing date as Victory Day.

Kim visited the Fatherland Liberation War Martyrs Cemetery in Pyongyang on Tuesday on the occasion of the 70th anniversary of the Korean War armistice, and was accompanied by Defense Minister Kang Sun-nam and other military leaders, according to the official Korean Central News Agency.

During his visit, Kim said the "miracle of July 27" is a "great victory of significance in the human history as they inflicted eternally indelible disgrace and defeat on the US imperialism, the chieftain of aggression, and prevented a new world war."

It marked Kim's first public appearance in 37 days. He was last seen in public attending a plenary meeting of the 8th Central Committee of the ruling Workers' Party on June 19.

Kim also visited the cemetery of martyrs of the Chinese People's Volunteers in Hoechang County, South Pyongan Province, to pay "high tribute" to the fallen Chinese soldiers on the occasion of the armistice anniversary, the KCNA said in a separate report.

Kim stressed that the "great victory won by the peoples of the DPRK and China at the cost of their blood is invariably displaying its great vitality still now, century after century."

Top officials accompanied Kim, including his powerful sister Kim Yo-jong and Jo Yong-won, secretary for organizational affairs at the ruling party, as well as Foreign Minister Choe Son-hui.

China fought alongside the North against South Korean, US and United Nations troops during the Korean War.

Meanwhile, the KCNA said a Russian military delegation led by Defense Minister Sergei Shoigu arrived in Pyongyang on Tuesday for commemorations of the armistice.

North Korean state media has not yet released any report on the impending arrival of the Chinese delegation led by Li Hongzhong, a member of the Political Bureau of the Central Committee of the Chinese Communist Party.

The planned visits by the Chinese and Russian delegations mark rare cases of the secretive regime inviting foreign guests to the country since imposing rigid border lockdowns against the COVID-19 pandemic.

With the invitation, the North appears to be emphasizing its solid ties with China and Russia in the face of growing defense cooperation among Seoul, Washington and Tokyo over Pyongyang's provocative acts. (Yonhap)
