To effectively tackle global health issues it's crucial that the Group of 20 nations use their June summit to overcome the barriers that have traditionally separated health experts and policymakers from financial and economic leaders.

Thus, the first-ever meeting between G20 health and finance ministers, scheduled to take place on June 28 on the sidelines of the leaders summit in Osaka, offers a chance for global collaboration at the highest levels on new funding mechanisms for the research and development of a wide range of drugs, vaccines, diagnostics, and treatments.

A push for unity was one of the key messages in a series of recommendations to G20 leaders released earlier this month by the G20 Health & Development Partnership, a London-based advocacy organization that aims to ensure G20 countries are coordinating their global health policies.
