The United States strongly supports Hong Kong's well-established traditions and Basic Law protections of internationally recognized fundamental freedoms, such as freedom of peaceful assembly, freedom of expression, and freedom of the press. We do not take sides in the discussion of Hong Kong's political development, nor do we support any particular individuals or groups involved in it.
Hong Kong's stability and prosperity have long benefited from a vigorous dialogue among its citizens and a firmly established tradition of the peaceful and orderly expression of differing views. In accordance with this tradition, we encourage all sides to refrain from actions that would further escalate tensions, to exercise restraint, and to express views on the SAR's political future in a peaceful manner.
