On 16 August 2011, Li Keqiang, Vice Premier of the People's Republic of China, began a three-day visit to promote development between Hong Kong and mainland China. The university was locked down. The mishandling by the police force caused the Hong Kong 818 incident. In a statement to the HKU community, the university vice-chancellor Professor Lap-Chee Tsui admitted that the security arrangements could have been better planned and organised, and apologised to students and alumni for not having been able to prevent the incident. He assured them that "the University campus belongs to students and teachers, and that it will always remain a place for freedom of expression". On 30 August 2011, the university council resolved to set up a panel to review issues arising from the vice premier's visit, to improve arrangements and to set up policies for future university events that are consistent with its commitment to freedom of expression.
