Sanctions and export controls: the US-led regimes targeting Russia, Iran, China, Venezuela, and North Korea

What it is

Sanctions are legally mandated restrictions prohibiting transactions with designated governments, entities, or individuals. The US deploys two parallel systems. The Office of Foreign Assets Control (OFAC) within the US Treasury administers financial sanctions, adding names to the Specially Designated Nationals (SDN) list and blocking their access to the US dollar system. The Commerce Department's Bureau of Industry and Security (BIS) administers export controls through the Export Administration Regulations (EAR), governing what technology may leave the US or be re-exported by third parties using US-origin equipment or software. The Foreign Direct Product Rule extends US jurisdiction to goods made abroad with American tools, reaching Dutch chipmaking machines and Taiwanese fabs. The two systems reinforce each other: a designation can cut a target from both finance and technology simultaneously. The European Union, UK, and UN Security Council run parallel frameworks, and sanctions reach scale only when major blocs align.

History

The modern architecture rests on the International Emergency Economic Powers Act (IEEPA, 1977), which gives the US president broad authority to block transactions in a declared emergency. The Cold War Cocom export-control group, disbanded in 1994, became the Wassenaar Arrangement in 1996, covering dual-use goods and arms across 42 member states. Iran sanctions intensified from 2006 through four UN Security Council rounds, were partially suspended under the 2015 JCPOA, then reinstated under US maximum pressure from 2018. Russia sanctions escalated after the 2014 annexation of Crimea and again after the February 2022 full-scale invasion of Ukraine. The chip-controls strand opened with US Commerce Department rules in October 2022 restricting advanced semiconductors destined for China. Venezuela entered US sanctions focus primarily after 2017; North Korea has faced UN Chapter VII sanctions continuously since 2006, when Pyongyang conducted its first nuclear test.

Current state

As of early July 2026, Russia faces over 16,500 OFAC designations plus a G7 price cap; the EU's dynamic formula set the seaborne crude cap at US$44.10 per barrel from February 2026 (see EU의 동적 가격 상한제, 러시아산 원유를 배럴당 44.10달러로 낮추고 우랄유는 이미 그 아래). Iran faces US maximum-pressure sanctions and contested IAEA nuclear-site access; Doha talks concluded in July 2026 and their durability is uncertain. China is subject to BIS chip controls rather than OFAC designations; a May 2026 US-China trade framework opened narrow carve-outs for certain Nvidia H200 purchases, but Beijing urged domestic sourcing, leaving deliveries near zero. Venezuela faces OFAC designations on state oil company PDVSA and senior officials, with periodic US waivers for limited transactions. North Korea confronts UN Chapter VII sanctions and comprehensive US SDN designations; the June 2026 commissioning of the Choe Hyon destroyer (see 북한, 핵 탑재 가능 최초 구축함 취역, 원양 해군 야욕 과시) showed Pyongyang expanding military capacity despite them.

Relationships

The five targets share evasion networks. Russia and Iran both use shadow fleets of uninsured tankers to bypass price caps and Western port restrictions. The Garantex exchange and its Grinex successor (see 미 재무부, 자금세탁 거점 붕괴 속에 Garantex와 후계 Grinex를 재지정) routed sanctioned Russian value through Kyrgyz shells before OFAC redesignated both in April 2026. North Korea partly finances its weapons programme through cybertheft and arms sales to Russia, a sanctions-evasion loop between two designated regimes. China has countered chip controls with its own restrictions: rare-earth processing bans and, in June 2026, a dual-use blacklist targeting 40 Japanese defence entities (see 중국, 이중용도 수출 규제 2차 강화로 일본 방산 관련 40개 기관 블랙리스트 추가). US restrictions on AI model exports (see 미국, Anthropic의 최고 성능 모델을 전 세계 모든 외국인에게 차단) in mid-2026 extended the export-controls logic from hardware to software, opening a new contested front.

What to watch

• Iran: whether the July 2026 Doha nuclear agreement holds long enough to generate phased OFAC sanctions relief, or collapses and pushes Iranian oil back through the same evasion channels used at peak maximum pressure.
• Shadow-fleet enforcement: the G7 oil cap works only if port states, flag registries, and insurers act; evasion has expanded to Chinese-owned vessels, testing the Western enforcement perimeter.
• BIS Entity List: new additions after the May 2026 US-China trade truce remain a live risk; any disclosed diversion of advanced chips to Chinese military end-users would reset the bilateral technology standoff.
• Venezuela: the Trump administration's PDVSA licence regime has oscillated; Chevron waivers and oil-for-debt swap proposals can shift the posture with little notice.
• DPRK proliferation financing: how Pyongyang sustains weapons development by routing cybertheft proceeds and arms-sale revenue through third-country shells despite the UN sanctions architecture.
