Chinese Container Ships Successfully Navigate the Strait of Hormuz Amid Ongoing Conflict

On March 30, 2026, two Chinese container ships, the CSCL Indian Ocean and the CSCL Arctic Ocean, successfully transited the Strait of Hormuz on their second attempt after initially turning back on March 27. This marked a significant moment as these vessels became the first non-Iranian flagged container ships to leave the Persian Gulf since the onset of the U.S.-Israeli conflict with Iran on February 28. The ships, operated by China’s COSCO Shipping, sailed in close formation and were reported to be heading towards the Gulf of Oman at an elevated speed.

The Strait of Hormuz, a critical maritime corridor for global oil shipments, has seen a drastic reduction in traffic due to heightened tensions following the conflict involving the U.S. and Israel against Iran. Prior to the conflict, approximately 151 vessels transited the strait daily; this number has plummeted to just a few vessels per day, primarily Iranian tankers. Iran's Islamic Revolutionary Guard Corps (IRGC) has enforced strict controls, effectively creating a "toll booth" system where only vessels from "friendly nations" such as China, India, Russia, Iraq, and Pakistan are permitted passage.

Iran has asserted its control over the Strait of Hormuz, stating that it will determine which vessels can pass through. The IRGC has warned that ships linked to the U.S. or its allies would be blocked. This has led to a precarious situation for shipping companies, which have adopted various tactics to navigate the strait, including switching off their AIS tracking systems and sailing at night to reduce visibility.

Iran's Foreign Minister Abbas Araghchi has publicly stated that friendly nations are allowed to transit the strait, while simultaneously emphasizing that aggressor nations would be denied passage. This duality reflects Iran's strategic use of the strait as a geopolitical tool. Meanwhile, U.S. President Donald Trump has claimed that Iran allowed ten oil tankers to transit as a goodwill gesture, although details remain unclear.

Critics have raised concerns about Iran's control over the strait, labeling it as a violation of international maritime law. The Gulf Cooperation Council has condemned Iran's actions, asserting that the collection of fees for passage constitutes aggression against global trade. Maritime experts have also expressed skepticism regarding the safety of navigating the strait under current conditions, given the risks posed by Iranian military actions.

Reports indicate that while some vessels have successfully navigated the strait, many others remain stranded or have turned back due to Iranian warnings. The situation is fluid, with ongoing diplomatic efforts to secure safe passage for various nations' vessels. The exact number of ships that have managed to transit remains uncertain, as many vessels have turned off their tracking systems to avoid detection.

The future of maritime traffic through the Strait of Hormuz remains uncertain. Analysts predict that the longer the conflict continues, the more severe the impact on global energy supplies and economic stability will be. As shipping companies weigh the risks of navigating the strait, the potential for increased military presence or international naval escorts may influence future shipping routes and practices.
