G20 Okayama Health MinistersMeeting: lessons learned and way forward.

The third G20 Health Ministers' Meeting was held in Okayama, Japan on October 19-20, 2019. The authors were involved in the decision making of the substantial issues of this meeting including theme setting, schedule management, facilitating the discussion, and preparation for the ministers' meeting. Here, we summarize our lessons of experience from hosting G20 Okayama Health Ministers' Meeting as: i) Utilizing the occasion of existing major health related meeting to gain efficiency; ii) Collaboration with other G20 tracks such as finance can function as a tool to facilitate inter-sectoral collaboration within other G20 members; iii) Two-day Health Working Group before the ministerial meeting provides sufficient time for negotiation of the declaration text; and iv) Inclusion of residents and representatives of the host city provides great opportunity to create G20 legacy. Such an experience of Japanese policymaking is rarely shared in English and the lessons learned from our experience shall provide meaningful advice for Saudi Arabia colleagues who are to hold the next G20 Health Ministers' Meeting as well as for the preparation of other G20 ministerial meetings. 2019, National Center for Global Health and Medicine.
