Premier Wen Jiabao and his DPRK counterpart Kim Yong-il attended the signing ceremony.
The Chinese Premier arrived in Pyongyang at around 11:00 am local time (0200 GMT) Sunday morning and was greeted at the airport by DPRK's Kim Jong-il.
Wen is in Pyongyang for a three-day visit at the invitation of the Workers' Party of Korea Central Committee and the DPRK government.
