EU and GCC Issue Joint Statement Rejecting Iranian Sovereignty Claims Over the Strait of Hormuz

Background: The Escalation That Led to the Statement

The joint statement came against a backdrop of severe military escalation in early July 2026:

• July 6–7: Iran's Revolutionary Guards fired missiles at multiple commercial ships in the Strait of Hormuz. According to reports, the Qatari LNG tanker Al Rekayyat was struck off the Omani coast, and a Saudi-flagged oil tanker was also targeted . The UK Maritime Trade Operations agency confirmed a tanker was hit by an unknown projectile about 8 nautical miles east of Oman's Limah, causing a fire .

• July 11: Iran declared the Strait of Hormuz closed to "unauthorized" traffic after striking a vessel that had "jeopardized maritime security." Iran's Revolutionary Guards Navy stated that a vessel that had switched off its systems was struck and brought to a halt, warning that any retaliation would be met with a "severe response" .

• US military response: The United States launched multiple rounds of retaliatory strikes. One wave targeted 140 Iranian military installations, and additional rounds continued through July 13. Reports indicated over 300 Iranian military targets were struck across the campaign . The US-Iran interim ceasefire deal collapsed on July 8 after the attacks .

Why This Statement Matters

The EU-GCC joint statement is significant for several reasons. It represents a rare unified position between European nations and Gulf Arab states at a moment of acute crisis. By grounding their position in UNCLOS and UN Security Council Resolution 2817, the two blocs anchored their diplomatic response in established international legal frameworks rather than unilateral action. The explicit rejection of "transit fees" or "clearance conditions" directly countered Iran's reported demands that vessels seek Iranian approval before transiting the strait .

At the time of the statement, the Strait of Hormuz — through which about 20% of the world's oil passes — was effectively under siege, with tanker traffic at a near standstill and the threat level raised to "severe" by the US-led Joint Maritime Information Center .

Looking Ahead

The statement committed the EU and GCC to continued diplomatic engagement through the IMO and other international bodies, with the goal of protecting shipping and pursuing a negotiated resolution. However, the statement did not specify enforcement mechanisms or consequences for non-compliance, leaving open questions about how the international community would respond if Iran continued its attacks on commercial shipping in the waterway.
