Among those sanctioned are Wang Chen, a member of the 25-person Politburo, one of China's top decision-making bodies, and Tam Yiu-chung, the only Hong Konger on the committee that drafted the national security law.
Many figures on the list released by the State Department Wednesday had previously been barred by the Trump administration from traveling to the US, along with their family members. Designation under the HKAA brings with it financial sanctions, which can include restrictions on banking, loans from US financial institutions, buying property or dealing with US entities.
