Hong Kong singer and activist Denise Ho wants U.S. lawmakers and companies to criticize Beijing's actions in Hong Kong to help change the Chinese Communist Party's behavior.

Ho said Monday that Beijing was using its power and influence to quash dissent around the world, and urged businesses who invest in China and Hong Kong, a former British colony, to robustly support human rights and democracy.

The Chinese territory has been rocked by more than three months of sometimes violent clashes, with demonstrators angry about what they see as creeping interference by Beijing in Hong Kong's affairs, despite a promise of autonomy. Beijing is exporting its authoritarian values around the world, Ho said.
