In light of a troubling wave of disappearances of Chinese activists, Freedom House calls upon U.S. Assistant Secretary of State for East Asian and Pacific Affairs Kurt Campbell to formally request visitation with disappeared artist and activist Ai Weiwei, as well as others whose whereabouts are unknown, during his visit to Beijing tomorrow. Freedom House also calls on Campbell and other senior Administration officials to make clear, publicly and privately, that human rights in China are a central issue in the U.S.-China relationship.
