On 14 February, the Kharon Brief carried a post saying that the US State Department has imposed restrictions for 2 years on 13 individuals and entities supporting proliferation activities in Iran, North Korea and Syria. The restrictions were announced on 3 February and published in the Federal Register on 14 February. As a result of the listing, those named cannot supply US Government agencies with goods or services and they cannot receive Government funds or certain Government sales. Neither can they receive export licences for controlled items. Some of those listed were already subject to US sanctions. The entities include Russian and Chinese ones.
