North Korean leader Kim Jong Un vowed on Wednesday to keep strengthening relations with China, describing recent summit talks with President Xi Jinping in Pyongyang as a “historic occasion”.

In a congratulatory message to Xi marking the 105th anniversary of the founding of the Communist Party of China, Kim said it was Pyongyang’s “steadfast stand” to steadily develop relations with Beijing, according to the North’s state-run Korean Central News Agency.

“It is the steadfast stand of our Party and government to steadily develop the DPRK-China friendly relations with long and historical roots and with socialism as their core,” Kim said in the message.

“The recent Pyongyang summit was a historic occasion of deepening the comradely friendship and trust between us,” Kim said, adding that the two leaders had reaffirmed their “unshakeable will” to advance traditional bilateral ties.

Kim also said he was ready to work with Xi to further develop “friendly and cooperative relations” between North Korea and China, calling them “the common wealth of the peoples of the two countries”.

The message comes weeks after Xi made a rare visit to Pyongyang, where the two leaders pledged to strengthen ties such as Pyongyang’s increasingly close military relationship with Russia. (AFP)
