South China Sea and East China Sea Sanctions Act of 2023

This bill authorizes U.S. sanctions against Chinese officials and entities involved in activities like military construction, resource access obstruction, or actions threatening stability in the South China Sea and East China Sea. It allows the president to block their U.S. assets, deny visas, restrict exports, and prohibit U.S. investments in sanctioned individuals or entities. The sanctions target those responsible for reclamation, coercion against other nations, or militarization in disputed waters, as defined in the bill. The law aims to enforce international law following a 2016 arbitration ruling on China's maritime claims.
