BEIJING, Sept. 9 (Xinhua) -- Xi Jinping, general secretary of the Central Committee of the Communist Party of China (CPC) and Chinese president, on Sunday sent a congratulatory message to Kim Jong Un, top leader of the Democratic People's Republic of Korea (DPRK), on the 70th founding anniversary of the DPRK.

On behalf of the Communist Party of China (CPC), the Chinese government and people, as well as in his own name, Xi extends his warm congratulations and sincere wishes to Kim, the Workers' Party of Korea (WPK) and the DPRK government and people.

Kim is the chairman of the WPK and chairman of the State Affairs Commission of the DPRK.

In the message, Xi said the people of the DPRK have attained remarkable achievements in the cause of socialist revolution and construction over the past 70 years.

"In recent years, comrade chairman has led your party and people into taking proactive measures in social and economic development and achieved important results, and the development of socialism in the DPRK has entered a new historical stage," Xi said, "I'm really pleased to see all this."

Xi stressed that China and the DPRK are friendly neighbors linked by a mountain and rivers, and the China-DPRK traditional friendship forged and cultivated by the two countries' older generations of leaders is precious treasure shared by both sides.

The CPC and the Chinese government attach great importance to the China-DPRK friendly cooperative relations, unswervingly committed to maintaining, consolidating and developing such ties, Xi added.

Mentioning his three meetings with Kim this year, Xi said they have clearly charted the development direction of bilateral relations.
