China punishes Starlink use in territorial waters

For the first time, Chinese authorities have fined a foreign vessel for being discovered using SpaceX's Starlink internet service in its territorial waters. This precedent marks the first such measure, demonstrating Beijing's determination to control satellite communications within its maritime jurisdiction, according to an article by Paul Morgan on gCaptain.

Maritime law enforcement officers at the port of Ningbo in Zhejiang Province discovered the violation during a routine inspection, noticing a distinctive "rectangular antenna" mounted on the vessel's upper deck. The Ningbo Maritime Safety Bureau confirmed that the device was a low-orbit satellite receiver that continued transmitting data after the vessel entered Chinese waters, a direct violation of national telecommunications regulations.

Although authorities have not disclosed the vessel's name, home port, or the exact amount of the fine, this case represents a significant escalation in China's efforts to restrict satellite communications at sea. Ma Yanchao, director of the Ningbo Maritime Security Administration's command center, made the government's intentions clear:


– the official threatened.

According to the publication, Starlink crosses an imaginary line, as the American company has never had a license to operate in China, where foreign telecommunications services face strict controls. Chinese law requires all network traffic within the country to pass through state-owned gateways, but Starlink transmits data directly to foreign satellites, completely bypassing domestic infrastructure. Beijing views this as a fundamental threat to national communications security and data sovereignty.

The ban is not purely theoretical. According to Chinese regulations, any use of radio devices or frequencies requires official permission, and Starlink terminals, which function as both receiving and transmitting devices, have never received such permission. The regulation on direct satellite services, which took effect in June 2025, further strengthened this control, eliminating potential loopholes.

For ships, the rules are clear: Starlink terminals must be deactivated before entering Chinese territorial waters, which are generally defined as areas within 12 nautical miles of the coast. However, enforcing these rules has historically been difficult due to the difficulty of tracking and identifying satellite transmissions at sea.

This event is of critical importance for the maritime industry. Ningbo-Zhoushan is the world's busiest port by cargo tonnage, handling millions of tons of goods annually. Many international vessels are using Starlink for its superior speeds compared to traditional maritime satellite systems, using it for navigational support, crew welfare, operational communications, and logistics coordination.
