The partner institutions alternate hosting the Joint Institute Symposium which take place in Ann Arbor on even years and Beijing on odd years. Participation has grown dramatically as the JI has matured. In 2018, Michigan Medicine welcomed nearly 90 PKUHSC colleagues to Ann Arbor, the largest delegation in JI history and the biggest single-institution delegation ever to visit Michigan Medicine. About the same number of Michigan Medicine faculty traveled to Beijing for the 2019 JI Symposium last October. The 2020 symposium - also marking the tenth anniversary of the JI - will take place in Ann Arbor in the fall.
