On May 14th at 05:45 GMT, the United Kingdom Maritime Trade Operations reported the unauthorised boarding and hijacking of the Honduras-flagged Hui Chuan by Iranian forces. The vessel, anchored 38 nautical miles northeast of Fujairah within Iran’s Exclusive Economic Zone, was subsequently piloted into Iranian territorial waters.
Shipping intelligence outlet Lloyd’s List confirmed the Hui Chuan as a floating armory operated by Sinoguards, a China-based private maritime security company headquartered in Hong Kong. Floating armories operate in a legal grey zone. Positioned beyond territorial waters, they store weapons for security teams unable to carry arms into port. The vessel is registered under Marshall Islands-based SG Navigation, a jurisdiction often chosen for its tax and secrecy provisions.
Sinoguards presents itself as a commercially independent firm with no government or military affiliations, operating 17 points across key maritime corridors including a permanent base in Fujairah. In practice the firm largely protects Chinese economic interests, including Belt and Road Initiative assets, drawing its personnel from ex-military backgrounds across China, the United Kingdom, Ukraine and Nepal.
The Hui Chuan previously operated as the OceanResearcher1, a Taiwanese oceanographic survey ship retired after 2020. A trajectory from scientific research to armed private security that reflects the broader commercialisation of maritime force in the Gulf.
Iran’s action preceded talks between Donald Trump and Xi Jinping, in which Xi reportedly made clear China’s opposition to the militarisation of the Hormuz Strait, with Trump claiming Xi had offered to assist in keeping it open. Since wednesday Iran has permitted 40 Chinese commercial vessels to transit the strait without tolls, making a distinction between Chinese commercial interests and the private security infrastructure protecting them.
The Hormuz strait hosts multiple floating armories that have until now remained untouched amid regional tensions. Iran is sending a precise message: private security arrangements even connected to non-western state power offer no guarantee of safe passage. Only Iran does.
