Clean water resources and improved environmental infrastructure have a profound impact on the living and development of mankind. How to help developing countries improve capacity building in the field of water and environment, and solve the water resource and environmental management crisis in the process of economic and social development is not only the core of the UN 2030 Sustainable Development Goals (SDGs), but also an important path to build community of human destiny. Specifically, the developing countries are in different stages of economic development, as well as in water security and environmental treatment technology and management capabilities, which make them face challenges in the implementation of the UN SDGs. In order to make readers understand the current water security problems and countermeasures in developing countries, Chinese Journal of Environmental Engineering launched a special collection of "One Belt & One Road Water Security Challenges and Solutions". This collection focuses on the water security needs of typical developing countries along Belt & Road, such as Sri Lanka, Iran, Bangladesh, Myanmar and Kenya. Based on the practice and orientation of the CAS-TWAS CEWE in water science and technology international cooperation since its establishment in 2013. The collection analyzes and summarizes the core difficulties encountered by developing countries along Belt & Road in the process of improving water quality security and realizing sustainable utilization of water resources. The key countermeasures and series of solutions to the problem are discussed, in order to provide reference for deepening the scientific and technological cooperation under One Belt & One Road initiative. This collection consists of 6 articles, co-authored by the core team of CAS-TWAS CEWE, illustrates the background, model and future direction of China's international cooperation in water technology under the new global pattern.
