On August 24, 2022, President Xi Jinping exchanged congratulatory letters with President of the Republic of Korea (ROK) Yoon Suk-yeol to celebrate the 30th anniversary of the establishment of diplomatic relations between the two countries.

Xi Jinping pointed out, China and the ROK are always close neighbors facing each other across the sea, and our two peoples have always enjoyed longtime friendly exchanges. Over the past 30 years since the establishment of diplomatic relations between China and the ROK, with the joint efforts of both sides, China-ROK relationship has progressed with the times and developed in an all-round manner. It has achieved fruitful outcomes, delivered tangible well-being to the two countries and the two peoples, and as well made  important contributions to peace and development in the region and the world.

Xi Jinping pointed out that the past 30 years have undergone great changes and witnessed spring flowers and autumn harvest year by year. China-ROK relations have made glorious achievements in development, and the key is that the two sides have adhered to foresight, been consistent with the trend of our times, and kept enriching bilateral relations in the new era; the key is that the two sides have adhered to mutual respect and mutual trust, accommodated each other's core interests and major concerns, and increased understanding and trust through sincere communication; the key is that the two sides have adhered to win-win cooperation, deepened mutually beneficial cooperation and exchanges and mutual learning, and helped each other succeed and achieve common prosperity; and the key is that the two sides have adhered to openness and inclusiveness, and joined hands in safeguarding regional peace and stability, advancing integrated regional development, and upholding basic norms governing international relations. The precious experience deserves to be all the more cherished and we should be committed to it over the long term.

Xi Jinping stressed that currently, with the combined impact of changes and a pandemic both unseen in a century, the world enters a new period of turbulence and transformation. At this critical moment, the international community, including China and the ROK, can only defeat crises and tide over difficulties by embracing solidarity and cooperation. China and the ROK should be good neighbors, good friends, and good partners. I attach great importance to the development of China-ROK relations, and stand ready to work with President Yoon Suk-yeol to strengthen strategic communication, and lead the Chinese side and the ROK side to take the 30th anniversary of the establishment of diplomatic relations as a new starting point to grasp the overall trend, remove disruption, consolidate friendship, and focus on cooperation, to jointly create a brighter future of bilateral relations, and deliver more benefit to the two countries and the two peoples.

Yoon Suk-yeol in his congratulatory letter extended warm congratulations on the 30th anniversary of the establishment of diplomatic relations between the ROK and China. He said that the ROK and China enjoy geographical proximity and time-honored bond relations in history and culture. Since the establishment of diplomatic relations in 1992, both sides have achieved leap-forward development in cooperation in politics, economy, culture, and other fields, and the strategic cooperative partnership between the two countries has been continuously consolidated. The annual trade volume between the two countries has grown by almost 50 times, personnel inter-flow has increased by dozens of times, and various cultural exchanges have enhanced mutual understanding between the two peoples. This mainly benefits from efforts of every walk of life and the people of the two countries. During the call on March 25, I and President Xi Jinping reached important consensus on taking the 30th anniversary of the establishment of diplomatic relations between the two countries as an opportunity to work towards the new development of ROK-China relations. I hope that both sides will build on the spirit of mutual respect to explore new directions of cooperation and promote the development of bilateral relations in a more mature and sounder manner. To that end, I hope that both sides maintain close high-level exchanges, strengthen substantive cooperation in supply chains, and other fields of economy and security, environment, and climate change, and make tangible achievements recognized by the two peoples. I hope that the  commemorating events for the 30th anniversary of the establishment of diplomatic relations will further promote the exchanges and cooperation between the two countries and deepen the friendship between the two peoples.

On the same day, Premier Li Keqiang exchanged congratulatory messages with ROK Prime Minister Han Duck-soo. Li Keqiang expressed that China and the ROK are always close neighbors and inseparable cooperation partners. The Chinese side stands ready to work with the ROK side to take the 30th anniversary of the establishment of diplomatic relations as a new starting point to increase understanding and mutual trust, deepen exchanges and cooperation, promote the development of the China-ROK strategic cooperative partnership in a sound and steady manner, and make more new achievements. Han Duck-soo noted that since the formation of the new ROK government, the ROK and China have maintained close communication and exchanges. I expect that the two sides will further deepen high-level exchanges, strengthen cooperation in supply chains, culture, environment, and other fields, accelerate the second-phase negotiations on the free trade agreement between the two countries, and work towards better development of bilateral relations.
