The UN Security Council has decided to impose sanctions on three additional North Korean companies.

UN officials announced on Wednesday that the Security Council’s committee on sanctioning the North added one bank and two trading companies to a list of North Korean entities subject to sanctions, bringing the total to eleven. Those firms may have their assets frozen and will not be able to engage in any type of trade with UN member states.

China reportedly supported adding two North Korean firms to the list initially, but it apparently opted for a total of three under pressure from the U.S.

A diplomat from a Western nation said the newly added companies are considered to be important firms in the North. Another diplomat stressed that as additional entities are added to the list, he is confident a firm message will be conveyed to the North that it has to pay a price for its provocations.

The council’s recent decision comes after it unanimously adopted a presidential statement condemning North Korea’s launch of a long-range rocket on April 13th.
