Weeks after the 2014 Hong Kong class boycott campaign and Umbrella Movement broke out which demands genuine universal suffrage among other goals, Cardin among bipartisan colleagues joined U.S. Senator Sherrod Brown and Rep. Chris Smith's effort to introduce Hong Kong Human Rights and Democracy Act which would update the United States–Hong Kong Policy Act of 1992 and U.S. commitment to Hong Kong's freedom and democracy. "Civil society and democratic freedoms are under attack around the world and Hong Kong is on the front lines. The United States has a responsibility to protect human rights and defend against these threats," Cardin, chairman of the Senate Foreign Relations East Asian and Pacific Affairs Subcommittee said.
