Abstract: In “Healthy China” 2030 Plan, the construction of healthy cities is considered as a critical strategy to build healthy China. The constructed Child-Friendly Cities (CFC) may provide children with a prioritized environment for survival and development, which promotes children′s well-beings. In this study, the definition of CFC and the significance of health promotion in the construction of CFC were briefly introduced; CFC construction-related practices in five main aspects of children′s health promotion (nutrition, mental health, early development, health behaviors, and injuries) in 29 cities of 12 foreign countries were reviewed; the experiences and limitations in CFC construction in several cities of China were also summarized. The study intends to provide a reference for CFC construction in China during the 14th FiveYear Plan period.
