The spate of incidents is a reminder of the continued risks to ships crossing through Hormuz, even with military forces protecting vessels crossing by a route near Oman’s coastline.
The U.S. had issued what was supposed to be a 60-day authorization in late June, as part of a tenuous peace agreement with Iran to reopen the Strait of Hormuz.
The report suggests that Chinese companies are looking to spread risk across more suppliers and markets, while using technology to help manage that added complexity.
Industry groups have cautioned that even though a ceasefire between the U.S. and Iran remains in place, the presence of mines is a major risk for ships.
The two countries have a vital interest in maintaining security in the straits, including from accidents and piracy, Indonesian President Prabowo Subianto said.
