A group of U.S. legislators are seeking to exclude from the U.S. financial system foreign firms that have business relations with North Korean organizations, individuals or firms.

Under a bill cosponsored by 13 lawmakers, including Senator Jon Kyl, Washington would be allowed to suspend operations of foreign firms that engage in business dealings with North Korean financial organizations that are subject to U.S. sanctions.

The bill also seeks to sanction foreigners who purchase minerals extracted from the North.

The U.S. Congress is likely to pass the bill during its current session.
