Song Tao, China's special envoy to the Democratic People's Republic of Korea (DPRK), met high-ranking DPRK official Choe Ryong Hae on Friday.

Video filmed by Pyongyang's state news agency KCNA showed the Chinese delegation meeting with Choe, the secretary of the Central Committee of the Workers' Party of Korea.

KCNA said Song spoke to Choe about China's 19th CPC National Congress "in detail."

Song stressed that China's stance is to steadily develop the traditional friendly relations between the two parties and countries, the agency said.
