On March 14, 2025, Nick Watts, a professor from the National University of Singapore and a well-known scholar in the field of global health and sustainable development, was invited to visit the Institute for Global Health and Development of Peking University (i-GHD). We will conduct in-depth exchanges on the advancement of the "Planetary Health Axis System-PHAS" project and its international cooperation. Professor Gordon G. Liu, Dean of the National School of Development of Peking University, Professor Yang Jianan, Assistant Professor, Dr. Chen Ermo, Chief scientist of PHAS project, and some teachers and students of Peking University Global Health Institute participated in the symposium.

At the symposium, Dr. Chen Ermo first introduced the latest progress and future development plan of the PHAS project. By integrating data from various aspects such as human health, species health, environmental health and social health, the project aims to build a dynamic monitoring and comprehensive analysis platform that integrates health, environmental change and socio-economic indicators, and provide a data-driven decision support platform for global health governance.

In the ensuing discussion, Professor Liu Kuo-en and Professor Nick Watts focused on the idea of setting up an international centre for the PHAS programme at the National University of Singapore and agreed to further follow up on the matter. The two sides agreed that in the context of increasingly intertwined global public health challenges and climate change, strengthening cross-border and interdisciplinary collaboration and building a global research network will not only promote the accumulation and sharing of knowledge in related fields, but also provide a solid foundation for the construction of a future global health governance system.

Professor Nick Watts spoke highly of the forward-looking and systematic nature of the PHAS project in the field of global health, and expressed full expectation of further deepening cooperation between China and New Zealand and jointly promoting the expansion of the project at the international level, and was willing to actively promote the construction of the international center of the PHAS project in Singapore.

The talks laid a solid foundation for the international cooperation expansion of the "Planetary Health Coordinate System" project, marking another important step taken by the Institute of Global Health Development of Peking University in building global health public goods and promoting international health cooperation.
