SUMMER PALACE A "SENSITIVE SUBJECT"?

According to ScreenDaily, China's large press contingent at Cannes is in receipt of an official communication from Beijing that reminds them not to cover "sensitive subjects" which includes Lou Ye's SUMMER PALACE. Apparently a number of them have returned to China, but whether that was their plan all along (since the only Chinese film in competition, SUMMER PALACE, has already screened) or was a result of this communication is unclear.
