Australia has expressed deep concern about the violence in Hong Kong and the “increasing divide between the authorities and Hong Kong people.”

Australian Foreign Minister Marise Payne said it was crucial that police and protesters exercise restraint and take genuine steps to deescalate tensions.

Payne’s statement also said it was “essential that the police respond proportionately to protests.”
