"At a World Expo that asks what we can do to improve our societies and lives, Portugal dives back into the oceans, our source of life, biodiversity and connection to the world. Many years have passed since the unforgettable Expo '98, and many more since Portugal and Japan met for the first time, but the challenges facing the planet remain. It is therefore with the future in mind, and the well-being of us all, that we will present in Osaka, and also in Portugal, a Blue Dialogue of science, environment, economy, art and culture in defence of our common home: the blue planet."

Joana Gomes Cardoso, Commissioner General of Portugal's participation in Expo 2025 Osaka
