The University of Michigan has announced it will end its Joint Institute with Chinese Shanghai Jiao Tong University, following growing concerns from lawmakers about national security.

First established in 2006, this marks the third American university to end a joint institute partnership with a Chinese university in the past five months.

“International academic partnerships have deeply enriched our academic offerings and strengthened the global education of our students, and we will continue to pursue partnerships around the world as part of our academic mission,” University President Santa J. Ono said. “As we do so, we must also prioritize our commitment to national security.”

This comes after U.S. Rep. John Moolenaar, R-Michigan and chairman of the House Select Committee on the Chinese Communist Party, released a letter in October calling for the institute to be closed. Moolenaar cited Shanghai Jiao Tong University’s close ties with the Chinese government’s military operations as a main reason for concern.
