Who choreographs meetings between China and the United States? CNBC claimed in the video above that the whole meeting was choreographed, but by whom and how? Is there some kind of process, and do both sides know exactly what the other side is going to say in advance? How is the whole thing choreographed?
For the U.S. it is the Major Events Division and Visits Division of the Department of State who work with the visiting leader’s delegation and embassy staff to create a detailed schedule from beginning to end. The two sides work together and have to agree on the choreography of the event. There is also a Ceremonials Division. The Major Events Division works on major events and negotiations, and the Visits Division specializes in foreign liaisons.
For the CCP it's less obvious. Governments have event organizers who include a variety of staff, manage locations, proceedings, decorations, security liaison, host city arrangements, transport, airport logistics, hotels, credentials management, production contract management, press releases, host foreign government communications and agreements, intra-agency meeting arrangements.
