BEIJING — China on Monday announced unspecified sanctions against 11 U.S. politicians and heads of organizations promoting democratic causes, including Sens. Marco Rubio and Ted Cruz, who have already been singled out by Beijing. Foreign ministry spokesperson Zhao Lijian said Monday the 11 had “performed badly” on issues concerning Hong Kong, where China has cracked down on opposition voices following its imposition of a national security law in the semi-autonomous southern Chinese city last month. The number of Americans named by the ministry exactly equals the number of Hong Kong and Chinese officials placed on a sanctions list by the U.S.
