Entitled "Album of Ambassadors," the book contains a collection of materials from the archives of two countries' foreign ministries, including a total of 423 pictures.

The publication of the book coincides with celebrations of the 70th anniversary of the establishment of the two countries' diplomatic ties, Damdinsuren Davaasuren, state secretary of the Mongolian Ministry of Foreign Affairs, said at the launch ceremony.

"The book describes not only the life of ambassadors and their contribution to the development of Mongolia-China ties, but also covers many important events in the history of the bilateral relationship over the past 70 years," said Davaasuren. "Long live the solid friendship between the two peoples."

During the ceremony, Chinese Ambassador to Mongolia Xing Haiming expressed his deep respect for the ambassadors of the two countries.

"Over the past 70 years, great progress has been made in people-to-people exchanges, local exchanges, and party exchanges between the two countries," Xing said.

"Among them, the ambassadors of the two countries have actively worked to implement the consensus reached by leaders of both countries, connect the development strategies of the two countries, and (have) played an important role in the friendly and cooperative relations between the two countries," he added.
