The United States sanctions 13 parties tied to Iran's weapons procurement.

Reuters reported that the Treasury and State departments targeted parties in Russia, China, Hong Kong, Pakistan and Iran. The designations included a Beijing-based representative whom Treasury accused of coordinating purchases of finished systems and dual-use components.

Other named parties were accused of supplying electronics, aviation-related components, shipping services or defence-industry support. The designations are government allegations; Reuters also quoted an outside analyst who questioned whether the measures would materially impede Iran's capabilities.
