China and South Korea voiced their support in Seoul Thursday for a joint statement issued during the fourth round of six-party talks on the Korean Peninsular nuclear issue, and expressed readiness to jointly promote regional peace and integration.

The two countries viewed the six-party statement as an important document containing the goals and principles agreed upon for the talks, saying the statement has laid an important foundation for the endeavor to make the Korean Peninsular nuclear-free, according to a joint communique issued by China and South Korea.

It said all parties -- the Democratic People's Republic of Korea (DPRK), China, the United States, Japan, South Korea and Russia -- should show sincerity and flexibility in carrying out the joint statement adopted at their fourth round of talks in Beijing in September.

Thursday's Sino-South Korean joint communique was issued during a state visit here by Chinese President Hu Jintao.

China welcomed the positive progress achieved in reconciliation and cooperation between Seoul and Pyongyang, vowing to stand fast behind their efforts to seek better ties and eventual peaceful reunification, the joint communique said.

China appreciated the efforts of South Korea in improving ties between Seoul and Pyongyang and maintaining peace and stability on the Korean Peninsula and hopes it will go on with its active role in such endeavors, the communique said.

South Korea highly evaluated the constructive role played by China in promoting peace and development in northeast Asia, the document said.

The two sides agreed to work together in achieving peace and common prosperity on the Korean Peninsula and across northeast Asia, it added.
