From 2-4 June, 2024, the 9th edition of World Cities Summit (WCS) was successfully held in Singapore, with the theme "Liveable and Sustainable Cities: Rejuvenate, Reinvent, Reimagine." The Summit was attended by more than 3,500 mayors, government and city leaders, industry experts and change-makers from nearly 100 cities worldwide. Since the 6th (2018), 7th (2021) and 8th (2022) editions of the Summit, UPDIS was once again invited by Singapore's Centre for Liveable Cities to participate in multiple events, including the "Urban Leaders Roundtable," "Roundtable on the Future of Downtowns," and the "Young Leaders Symposium." For the first time, we have also organized a sub-forum and set up an exhibition booth, where we shared with the global audience Shenzhen's development experiences and UPDIS' expertise.
