NEW YORK -- The U.S., Australia, the U.K. and Canada expressed "deep concern" on Thursday over Beijing's approval of a national security law to be imposed in Hong Kong, a move seen as a major erosion to the city's autonomy.
"Hong Kong has flourished as a bastion of freedom," the countries said in a joint statement. "The international community has a significant and long-standing stake in Hong Kong's prosperity and stability."
