CITYNET Secretariat

The CITYNET Secretariat manages the programs and institutional activities of the network. With the support and engagement of members, the Secretariat promotes the CITYNET mission of increasing connections and building capacity across cities in the Asia-Pacific.

After over two decades of success and growth in Yokohama, Japan, 2013 marks the CITYNET Secretariat’s relocation to Seoul, South Korea. With this move comes new partnerships, innovative urban collaboration and an even greater network of knowledge and best practices.

Even with a new location, the mission remains the same. The CITYNET Secretariat pledges to work side-by-side with over 130 members and partners throughout the Asia Pacific region. With each member city and organization, we will continue to highlight and share successes while tackling challenges standing in the way of urban development.

As the Asia-Pacific region grows in economic, environmental, and technological importance, CITYNET is propelling cities toward the goal of urban sustainability, resilience and inclusivity.
