The government of China's Hong Kong Special Administrative Region (HKSAR) established an anti-mask law on Friday in the latest drive to end the prolonged violence.

HKSAR Chief Executive Carrie Lam told a press conference that the government has invoked the power under the Emergency Regulations Ordinance and passed the Prohibition on Face Covering Regulation to "create a deterrent effect against masked, violent protesters and rioters."

In fact, similar regulations are already in place in at least 15 countries, including France, Germany, and Canada, as well as dozens of states in the United States.
