Iran says US sanctions breach sovereignty of other nations

Background on the latest US sanctions

The United States announced a new round of economic measures targeting Iran in early 2024. The sanctions focus on entities linked to Iran's nuclear and missile programs, as well as individuals alleged to be involved in regional militant activities. The Treasury Department's Office of Foreign Assets Control (OFAC) listed dozens of firms, banks, and shipping companies, restricting their access to the US financial system.

According to the official announcement, the measures are intended to increase pressure on Tehran to comply with existing nuclear agreements and to curb the flow of weapons to proxy groups in the Middle East.

Legal basis cited by Washington

U.S. officials argue that the sanctions are grounded in national emergency powers granted by the International Emergency Economic Powers Act (IEEPA). They also reference United Nations Security Council resolutions that call for member states to prevent Iran from acquiring materials that could be used for weapons of mass destruction.

• Asset freezes for more than 50 companies operating in the energy sector.
• Travel bans on senior officials linked to the Revolutionary Guard.
• Restrictions on maritime insurance for vessels suspected of transporting prohibited goods.

Iranian response and accusations of colonialism

Iran's foreign ministry quickly issued a statement condemning the new measures. Spokesperson Esmaeil Baghaei described the United States' threat as a revival of "full scale classic colonialism" that disregards the sovereignty of other states. He emphasized that Iran will not be coerced by external pressure and called for respect of international law.

Spokesperson Esmaeil Baghaei's remarks

Baghaei told reporters that the sanctions represent an unlawful intrusion into Iran's internal affairs. He warned that such actions could destabilise the region and provoke retaliation. The foreign ministry released the full statement on its official website, where it also highlighted Iran's right to self‑defence under the United Nations Charter.

International law perspective

Experts note that the principle of state sovereignty is enshrined in Article 2(1) of the UN Charter, which obliges all members to respect the territorial integrity and political independence of other nations. The doctrine of nonintervention further restricts any state from using coercive measures that aim to influence the internal policies of another state.

Sovereignty and nonintervention principles

While sanctions are a common tool of foreign policy, their legality often hinges on whether they are imposed unilaterally or under a multilateral framework. The United Nations provides a mechanism for collective sanctions, but unilateral actions may be challenged as breaches of the nonintervention norm.

The full text of the UN Charter is available at the United Nations website.

Potential impact on regional dynamics

Analysts warn that the new sanctions could have several ripple effects:

1. Reduced foreign investment in Iran's oil and gas sector, leading to lower export revenues.
2. Increased difficulty for Iranian shipping firms to obtain insurance, which may push them to use alternative routes or illicit services.
3. Heightened tensions between Tehran and Washington, potentially spilling over into proxy conflicts in Iraq, Syria, and Yemen.

Economic strain could also push Iran to deepen ties with other sanction‑resistant partners, such as Russia or China, reshaping trade patterns in the region.

What experts say

Policy scholars at the Brookings Institution argue that the United States is using sanctions as a lever to extract concessions without resorting to military force. They note that the effectiveness of such measures depends on the target country's ability to find alternative financing and on the willingness of third‑party states to enforce the restrictions.

A recent analysis can be found in a Brookings report on US sanctions policy, which highlights both the strategic intent and the practical limitations of unilateral economic pressure.

Meanwhile, a Reuters report from April 2024 quoted Iranian officials describing the sanctions as an attempt to re‑impose a colonial order on the Middle East. The article provides additional context on the diplomatic fallout and the reactions of regional allies.

In summary, the latest US sanctions have sparked a sharp diplomatic clash, with Iran framing the measures as an infringement of its sovereign rights. The episode underscores the ongoing tension between unilateral coercive tools and the norms of international law that seek to protect state independence.
