On December 5, 2024, Vice Foreign Minister Sun Weidong met with Secretary of State of the Ministry of Foreign Affairs and International Cooperation of Cambodia Un Kheang. The two sides had an exchange of views on China-Cambodia relations and cooperation in training diplomatic officials.

Sun Weidong said that China and Cambodia are ironclad friends who share weal and woe and help each other. Not long ago, President Xi Jinping held talks with President of the Cambodian People's Party and President of the Senate Samdech Techo Hun Sen, reaching important common understandings on building a high-quality, high-level and high-standard China-Cambodia community with a shared future. Amid an evolving and turbulent international situation, China and Cambodia should uphold the spirit of the Five Principles of Peaceful Coexistence, faithfully implement the important common understandings reached between the leaders of both countries, enrich the "diamond hexagon" bilateral cooperation framework, accelerate the development of the "Industrial Development Corridor" and the "Fish and Rice Corridor", enhance multilateral cooperation, and contribute to the modernization of both countries. The two sides should strengthen cooperation in training diplomatic officials and research on international issues, and elevate the level of their respective diplomatic teams.

Un Kheang thanked China for its long-term valuable support to Cambodia, praised the Belt and Road Initiative for benefiting developing countries, and expressed Cambodia's willingness to deepen comprehensive strategic cooperation with China, jointly practice true multilateralism and firmly promote the process of economic globalization. The Cambodian side is ready to deepen cooperation with China in training diplomatic officials and research on international issues to help build a stronger contingent of personnel involved in foreign affairs.
