Beijing's efforts to revive the six-nation nuclear disarmament dialogue with North Korea will still be pursued amidst China's efforts to continue assisting North Korea in boosting economic and trade reforms, reports Xinhua News Agency.

North Korea's Premier Choe Yong-rim met China's Premier Wen Jiabao, in an official visit Monday night to discuss economic cooperation, with the two leaders pledging to promote trade, investment and economic cooperation.

"Under the context of the complicated regional and international situation, the parties, governments and peoples of China and the DPRK made joint efforts to push forward bilateral ties," Premier Wen addressed Premier Choe, admiring North Korea's achievements in improving its economy and expressing willingness of his government to continue the assistance within its capability.

Before the supposed peace talks of North Korea's denuclearization, its strongman Kim Jong-il made frequent visits to China with hopes of retaining China's favor even after the leadership had passed on to his youngest son. Chinese President Hu Jintao told media he has been convincing North Korea's leader to open its nation to economic prosperity by affording him tours to China's enormous industries.

On Monday's meeting with North Korean Premier, China's Wen urged Premier Choe to accelerate mutually beneficial cooperation in trading, investments, infrastructure, agriculture and protection of natural resources.

In response, Premier Choe commited Pyongyang's cooperation with China in trade and infrastructure and welcomed Chinese traders in investing and operating in North Korea, The Korea Times reported.

Included in the official visit were Vice Premier Ro Tu-chol and some economic officials. The delegates are expected to meet with Chinese President Hu Jintao and have a series of tours to Shanghai, Nanjing and Yangzhou during their five-day visit.
