Harvard University President Lawrence H. Summers discussed Yang’s case with Chinese officials when he visited China in 2002.
Last December, more than 100 Harvard faculty members signed two letters calling for Yang’s release. The letters were addressed to Chinese Premier Wen Jiabao, who was speaking at the Business School that week.
A Harvard official has said that the University again raised concerns about the case with Chinese officials in the days leading up to Wen’s visit.
Summers’ spokesperson Lucie McNeil said yesterday that she is not aware of any further action taken by the University regarding Yang’s detainment.
