作者： Ma Xuejiao Lu Shenning Ding Wei Deng Shanying Wang Duoquan Xiao Ning Mlacha Yeromin Husain Lewis Zhou Xiaonong National institute of Parasitic Diseases Chinese Center for Disease Control and Prevention (Chinese Center for Tropical Diseases Research) NHC Key Laboratory of Parasite and Vector Biology WHO Collaborating Center for Tropical Diseases National Center for International Research On Tropical Diseases Shanghai China University of Hong Kong Hong Kong China School of Global Health Chinese Center for Tropical Diseases Research Shanghai Jiao Tong University School of Medicine Shanghai China Ifakara Health institute Dar-es-Salaam Tanzania institute of Development Studies Brighton UK

Tripartite partnership, compared with the bilateral model, is envisioned as an opportunity to foster stronger and more trusting partnerships [1]. However, China has historically been characterized as principally reliant on bilateral engagement in global health [2]. The China-Tanzania cooperation Project on Malaria Control was conducted by National institute of Parasitic Diseases at China CDC and Chinese Center for tropical Diseases Research, Ifakara Health institute in Tanzania and funding agencies from 2015 to 2022, with an aim to explore the applicability of Chinese experience on malaria control to reduce malaria disease burden in the local context of Tanzania. In the tripartite project funded by the former UK Department for international Development (DFID) and later the Bill & Melinda Gates Foundation (BMGF), China's partners were expected to share the extensively parallel practices achieved from the control and elimination of malaria for over 70 years, UK's partners were to deliver resources and design global health strategies, while Tanzanian local staff collaborated with triangular partners to ensure the project implementation [3]. In the project, the trilateral cooperation has transparent management mechanism to ensure the concrete management and implementation of the project [4] (Additional file 1: Figure S1). This Brief is to provide recommendations for China's engagement in global health by distilling the experience from the innovative tripartite partnership of the project.
