The coronavirus is not the first public health challenge the United States and China needed to manage. When AIDS, tuberculosis, and malaria still wreaked havoc across the world in the early 2000s, Jack Chow, the top health diplomat at the State Department, helped spearhead negotiations to establish and finance the Global Fund to fight these three diseases and managed many of the tough negotiations between the United States and China. Chow explains how he coordinated with Beijing on public health amid other strategic tensions, drawing lessons for today's coronavirus pandemic from his work on these three other diseases.
