BEIJING - China and the Republic of Korea (ROK) agreed that all parties concerned should work together to maintain peace and stability on the Korean Peninsula and in the region, a Foreign Ministry spokesman said Tuesday.

Foreign Ministry Spokesman Hong Lei made the remarks at a daily press briefing by addressing Vice Foreign Minister Zhang Zhijun's attendance at the fourth high-level strategic dialogue between China and the ROK in Seoul on Tuesday.

Zhang and ROK First Vice Minister of Foreign Affairs and Trade Park Suk-hwan hosted the dialogue together, Hong said.

On the same day, Zhang also met with ROK Foreign Minister Kim Sung-hwan and Unification Minister Yu Woo-ik, respectively.

They reviewed the development history of China-ROK relations, and mostly spoke about celebratory activities to mark the 20th anniversary of the establishment of diplomatic ties next year, Hong said.

They also exchanged views on the development direction of the two countries' relations, Hong said. "They all agreed to work together to push forward friendly cooperation in all areas, in order to bring benefits to both countries and their people."

There have been some reports saying that the dialogue was meant to discuss the current situation on the Korean Peninsula, following the death of Kim Jong-il and the fishing conflict between China and the ROK.

Hong said it has been a regular dialogue since the two countries started it in 2008, and it is held by both sides on a rotating basis.

The third high-level diplomatic strategic dialogue between the two nations was held in Beijing in September 2010. The second one was held in Seoul in April 2009 and the first one in Beijing in December 2008.
