A Joint Declaration was released in Tokyo, Japan on Wednesday, May 9, 2018, at the conclusion of the 7th Japan-China-ROK Trilateral Summit. It includes several references to public and cultural diplomacy:

Acknowledging the importance of trilateral cultural exchanges through the East Asian Cultural Cities Program, we congratulate the designation of 2018 East Asia Cultural Cities and expect that cultural exchanges among the present and previous cultural cities will be promoted. Recognizing the significance of education cooperation in deepening mutual understanding, we also praise the trilateral commitment to promoting student exchanges in the field of higher education through the expansion of Collective Actions for Mobility Program of University Students in Asia (CAMPUS Asia), and expect the discussion would continue to further promote the program.

Considering the significance of public diplomacy in enhancing understanding and friendship among the people of the three countries, we welcome the continued consultations on the trilateral forum on public diplomacy.
