Considering the drastic changes in the nature of conflicts, humanitarian organizations (HOs) and donors, investing more attention into impartiality is critical for HOs if they are to survive and improve the quality of their humanitarian activities. As one of the four fundamental humanitarian principles, impartiality has critical implications for humanitarian action in relation to three aspects: its symbolic meaning for humanitarian action, its procedural significance for humanitarian access, and its operational importance for needs assessments. This article analyzes how the practice of impartiality is challenged by the current humanitarian financing model from five angles: funding source, funding amount, funding allocation, financial management and funding categorization. To cope with these obstacles, we focus on the financial perspective and propose three suggestions for international HOs: first, digitally innovating the humanitarian financing model to ensure that overall humanitarian needs are covered; second, strengthening engagement with non-traditional donors such as the Gulf countries and China, with a focus on infrastructure; and third, developing a hybrid financing model, with case studies from UNICEF and the International Committee of the Red Cross.
