WASHINGTON— The United States has determined Pyongyang used the chemical warfare agent VX to assassinate the half-brother of North Korean leader Kim Jong Un in Malaysia in 2017 and has imposed sanctions in response, the U.S. State Department said on Tuesday.
The prohibitions appeared largely symbolic, such as sales to North Korea under the Arms Export Control Act and barring the export of national security-sensitive goods and technology to North Korea, which has no relations with the United States.
