The USS Benfold operated near Mischief Reef in the South China Sea, challenging China's new law requiring foreign vessels to give notice before entering claimed waters. The USS Carl Vinson also conducted training exercises in the region. China responded by tracking the USS Benfold, asserting its sovereignty over the Spratly Islands. The US Navy maintained its operations were lawful, emphasizing freedom of navigation. China has built military infrastructure in the Spratly Islands, reinforcing its territorial claims.
