Tropical diseases, the transmission of which is affected by multiple natural and social factors, pose a great challenge to global public health, notably in African countries. During the past several decades, China and African countries have continuously collaborated for the control of neglected tropical diseases and malaria, which has become an important part of global South-to-South cooperation and global health governance. This article reviews the history of China-Africa cooperation for tropical diseases control, summarizes the experiences and achievements over the past decade, analyzes the current challenges in the coopera tion, and proposes future recommendations. The China-Africa cooperation has achieved significant progress in the control of tropical diseases, such as malaria, schistosomiasis, and filariasis, and established a China-Africa cooperation network for tropical diseases control. Through the "Three-Step" strategy of China-Africa cooperation, the effectiveness of China's integrated control strategies has been validated in Africa, and the application of China's tropical disease control technologies has been promoted in African disease-epidemic countries. Currently, China-Africa collaboration, however, still experiences multiple realistic challenges, such as insufficient resources, difficulty in technology transfer, and weak primary healthcare systems. In the future, both sides are recommended to further strengthen policy coordination, deepen technological cooperation, innovate cooperation models, aiming to continuously promote the high-quality development of China-Africa cooperation for tropical diseases control.

Malaria remains one of the most serious public health problems in tropical and subtropical countries and regions. In the control of the vector Anopheles, insecticide-treated bed nets and indoor residual spraying, which have been promoted to interrupt malaria transmission by only preventing indoor blood-sucking by adult mosquitoes, consequently have been widely used in malaria-endemic areas. However, the efficacy of these measures in interrupting malaria transmission is gradually decreasing due to the development of mosquito resistance. In contrast, Anopheles larval source management can effectively reduce the population density of indoor and outdoor blood-sucking, wild and domestic mosquitoes. It can also be combined with adult mosquito control to become an important adjunct to existing adult mosquito control measures. In more than 70 years of malaria control and elimination in China, according to different conditions in different places, exploration and practice have been carried out in different types of control of malaria Anopheles larvae, such as habitat modification, habitat manipulation, larviciding, and biological control. These efforts have accumulated rich experience and resulted in strategies tailored to local conditions, integrated control, community involvement, and methodological innovation. This paper outlines the main practices and basic strategies of Anopheles larval source management for malaria control in China, with the aim of providing references for malaria control in other regions where malaria is still endemic.
