On 3 July 2019, in a statement in response to the Storming of the Legislative Council Complex two days earlier, Zhang said that he had been "disheartened by the violence" and that he "would like to condemn such acts". In response to a backlash from some 2,000 HKU students, alumni and staff, he stated on 11 July that he opposed violence "by any party, and at any juncture". Zhang agreed to a request by the HKU Student Union to participate in a forum open to students, staff, alumni and the media.
