The Strait of Hormuz remains a flashpoint as Iran expands control and enforces maritime regulations, with new incidents including Chinese ship passages and a South Korean vessel attack through May 15, 2026. Iran permitted over 30 Chinese-affiliated ships to transit the strait under its new conditions, showcasing strategic cooperation with Beijing. Meanwhile, debris from the May 4 attack on South Korea's HMM Namu arrived for analysis after being struck by two airborne objects, marking the 33rd civilian vessel incident since February. Iran's naval dominance continues with expanded control zones (now 321-482 km) and submarine deployments, while global shipping faces mounting disruptions. Chosun Ilbo+4

The IRGC continues enforcing new maritime protocols amid heightened US naval presence. TASS+3
