Pyongyang attaches the greatest importance to its diplomatic ties with Beijing as it implements "economic improvement", experts said following a meeting between the top leader of the Democratic People's Republic of Korea and a visiting senior Chinese official.

DPRK leader Kim Jong-un met with Wang Jiarui, head of the International Department of Central Committee of the Communist Party of China, on Thursday to discuss strengthening relations between the two countries, according to a report on Thursday by Xinhua News Agency.

Kim said Pyongyang will cooperate with Beijing to elevate their friendship, which was established and nurtured by previous leaders.
