U.S. Customs and Border Protection says it is ready to block U.S. imports of seafood processed by North Korean laborers who work in China.
 
An Associated Press investigation tracked seafood processed by North Koreans working at Chinese factories and shipped to American stores, including Walmart and ALDI. The North Koreans aren't allowed to leave and receive only a fraction of their pay - most goes straight to the North Korean state.
 
This means that American consumers buying seafood labeled "Caught in the USA, Processed in China" may be subsidizing North Korea's government and supporting forced labor.
 
U.S. Customs and Border Protection said it would "pursue all enforcement actions and prohibit goods from importation as appropriate." The companies that responded also vowed to investigate ties with suppliers.
