On 30 July, the US Treasury Department announced that it was blocking the assets of Chongchongang Shipping Company and Ocean Maritime Management Company (“OMM”), both North Korean state-owned shipping companies. In July 2013, Panamanian authorities discovered and seized a concealed shipment of arms and related materiel from Cuba destined for North Korea aboard the Chong Chon Gang, a vessel owned by Chongchongang Shipping Company and managed by OMM. The shipment apparently violated a UN Security Council arms embargo on North Korea. According to a notice issued on 28 July 2014 by the UN Security Council Committee established to monitor the arms embargo, OMM played a key role in arranging the shipment. Also designated were 18 North Korean vessels in which these companies have an interest, including the Chong Chon Gang.
