Recently, I had the privilege of attending a commemorative event in Nelson, New Zealand, celebrating the 50th anniversary of its sister-city relationship with Miyazu City in Kyoto Prefecture. Reflecting on half a century of exchanges between the two cities and seeing the strong bonds their communities have built together, I was reminded of the significance of sister-city relationships and local government exchanges.

In recent years, local government international exchange initiatives have often been expected to deliver tangible economic benefits, such as increased tourism and export growth. While these are undoubtedly important outcomes, the commemorative event reinforced my view that the true foundation of local government exchange is, after all, the connections between people.

The relationship between Nelson and Miyazu has been sustained not only through ties between their local governments, but also through student exchanges, homestay programs, and the efforts of countless community members. Through these ongoing exchanges, mutual understanding and trust have been fostered over time, enabling the relationship between the two cities to flourish for more than 50 years.

Today, advances in digital technologies, including artificial intelligence (AI), have significantly reduced language barriers and the challenges posed by geographical distance, making communication across countries and regions easier than ever before. By using these technologies, we can connect with countries, regions, and people with whom we previously had little or no contact, better understand one another, and work more closely together.

At the same time, while AI and digital technologies are powerful tools for expanding the possibilities of exchange, I believe that no matter how much technology advances, the driving force behind maintaining and developing relationships between local governments will always be the human connections that underpin them. The trust built through meeting face-to-face, experiencing one another’s cultures and values, and developing friendships cannot be cultivated overnight, nor can it be replaced by technology.

Looking beyond our own communities, we can see growing signs of division and confrontation within the international community, driven in part by the spread of increasingly inward-looking, nation-first approaches. These tensions can leave us feeling uncertain about the future of the world. In times like these, I believe that genuine efforts to understand one another and build trust across national and regional boundaries, together with opportunities for people to connect with one another face to face, become all the more important.

The 50-year history of exchanges between Nelson and Miyazu served as a valuable reminder that people are at the heart of local government exchange. As local governments continue their international engagement, I hope they will cherish these people-to-people connections while embracing new technologies, to foster even richer and more meaningful exchanges in the years ahead.
