On 23 November, the 2023 East Lake • Mesoscience Forum was held at the East Lake International Centre in Chaoyang District, Beijing. The forum was under the guidance of the China Association for Science and Technology (CAST), hosted by the International Mesoscience Panel (IPM), organized by the Institute of Process Engineering of the Chinese Academy of Sciences (IPE-CAS), the National Key Laboratory of Mesoscience and Engineering, and the Chinese Society of Particuology, co-organized by the Beijing Association for Science and Technology, with support from the Bill & Melinda Gates Foundation, and the Shanghai JiDing Information Technology Company.

Lin Yin, Director of the International Organization Division, Department of International Cooperation of the International Department of CAST, delivered a speech at the opening ceremony of the forum. Bernd Albert Sachweh, Vice President of IPM, introduced the development status of IPM. Bojie Fu, academician of Chinese Academy of Sciences, Xiuwu Bian, academician of Chinese Academy of Sciences, Yiming Wei, Distinguished Professor and Vice President of Beijing Institute of Technology, and Jinghai Li, President of IPM, academician of Chinese Academy of Sciences, made academic reports respectively. The forum was hosted by Yang Ning, secretary-general of IPM and professor of IPE-CAS, with more than 100 representatives from eight countries attending the meeting.

The theme of the forum is "Science in Support of Sustainable Development Goals", which aims to apply mesoscience concepts to analyze the multi-level complexity of the United Nations Sustainable Development Goals (SDGs), to promote the application of mesoscience in the fields of climate change and human health, and to enhance the level of research on the achievement of the SDGs by human beings. In order to promote the wide application of mesoscience in the field of natural science research, the Youth Seminar on Sustainable Development was held during the same period to discuss the progress of fundamental research in mesoscience and the development of software based on mesoscience multiscale structural analysis.

The organization of this forum provided a platform for in-depth exchanges among the participants, which not only injected vitality into the long-term development of mesoscience, but also provided a new impetus for the promotion of scientific research in the service of sustainable development goals.
