Shanghai Fosun Pharm will invest $15 million in Partners Innovation Fund II, a fund that will invest in medical research products originating from Partners Healthcare System of Boston. Partners Healthcare includes three major Boston-area teaching hospitals that are associated with Harvard University: Massachusetts General Hospital, Brigham and Women’s Hospital and McLean Hospital. Fosun said it was interested in PIFII as an investment, but also for potential acquisitions and China rights to promising products.
