Duke University has pushed back the opening of its campus in Kunshan, China, by another semester because of construction delays and communication problems, according to The Chronicle, Duke’s student newspaper. The campus’s opening, which has already experienced several setbacks, has been delayed to the fall of 2014. Some Duke professors have questioned the effort to open the campus, raising concerns about academic freedom in China and the project’s finances.

Two of the project’s leaders at Duke responded to the latest setback in a letter to the newspaper. “What is notable is not that there have been delays or misunderstandings over construction issues, but that the three sponsors of DKU are working together in common purpose to move this project forward,” they wrote.

Their letter touted “new processes and personnel” put in place by the project’s partners to ensure that the completed buildings will be “widely acclaimed and an excellent home for world-class academic programs.” Duke is still waiting for the campus to receive final “establishment” approval from the Chinese Ministry of Education, the newspaper reported.
