North Korea's Kim congratulates Xi on third term, seeks 'beautiful future' for ties

North Korean leader Kim Jong Un has sent his "warmest congratulations" to Chinese President Xi Jinping on securing a third term as head of China's ruling Communist Party, state media reported Sunday.

The unusually prompt report from Pyongyang's official Korean Central News Agency came after the Chinese Communist Party's Central Committee elected Xi as its general secretary for another five-year term.

"Please accept my warmest congratulations to you upon the glad news that... you were elected again as the general secretary of the Party Central Committee," read Kim's message carried by KCNA.

"I, together with you, will shape more beautiful future of the DPRK-China relations meeting the demand of the times," Kim said, using the acronym of the North's official name.

Ties have fluctuated over the years due to Pyongyang's growing nuclear ambitions, but the two have been working to repair their relationship.

Xi, 69, was also reappointed head of China's Central Military Commission, keeping him in charge of the People's Liberation Army.
