In his April 16 op-ed, “The global loss of U.S. leadership,” Jackson Diehl covered much of the losses but not all. The United States is in danger of forfeiting its unquestioned leadership in global health, as it seems only a matter of time before China’s international health programs and financing dominate.

With the Organization for Economic Cooperation and Development, China, Russia and other lead regional countries, the United States should initiate a 21st- ­century Bretton Woods-like Conference on Global Health, recognizing the new and evolving geopolitical power structures emerging in global health.
