China Issues First Penalty for Starlink Use in Territorial Waters

Landmark enforcement at Ningbo signals zero-tolerance approach to unauthorized satellite comms

By Paul Morgan (gCaptain) – In a watershed moment for maritime telecommunications regulation, Chinese authorities have penalized a foreign vessel for illegally operating SpaceX’s Starlink internet service within territorial waters — the first enforcement action of its kind that signals Beijing’s determination to control satellite communications in its maritime jurisdiction.

Maritime law enforcement officers at Ningbo port in Zhejiang province discovered the violation during a routine inspection when they spotted a distinctive “micro rectangular antenna” mounted on the vessel’s top deck. The Ningbo Maritime Safety Administration confirmed the device was a low-Earth orbit satellite terminal that had continued transmitting data after the ship entered Chinese waters, directly violating national telecommunications regulations.

While authorities did not disclose the vessel’s identity or the exact penalty amount, the case represents a significant escalation in China’s enforcement of satellite communication restrictions at sea. Ma Yanchao, director of the command centre at the Ningbo Maritime Safety Administration, made the government’s intentions clear: “We will take this landmark first case as an opportunity to continue to intensify enforcement against illegal radio communication activities in our jurisdiction.”

Starlink crosses the imaginary line because it has never been licensed to operate in China, where foreign telecommunications services face stringent controls. Chinese law requires all network traffic within the country to pass through state-managed gateways, but Starlink transmits data directly to foreign satellites, bypassing domestic infrastructure entirely. Beijing views this as a fundamental threat to national communication security and data sovereignty.

The prohibition isn’t merely theoretical. Under Chinese regulations, any radio device or frequency usage requires official approval, and Starlink terminals — functioning as radio transceivers — have never received this permission. A direct-to-device satellite services regulation that took effect in June 2025 further strengthened these controls, closing potential loopholes.

For vessels, the rules are unambiguous: Starlink terminals must be deactivated before entering Chinese territorial waters, typically defined as within 12 nautical miles of the coast. However, enforcement has historically been challenging due to difficulties in tracking and identifying satellite transmissions at sea.

The timing couldn’t be more significant for the maritime industry. Ningbo-Zhoushan ranks as the world’s busiest port by cargo tonnage, handling millions of vessels annually. Many international ships have adopted Starlink for its superior speeds compared to traditional maritime satellite systems, using it for navigation support, crew welfare, operational communications, and logistics coordination.

The Ningbo Daily report acknowledged that enforcing restrictions on foreign satellite equipment has been difficult, and many international vessels may have continued using Starlink within Chinese waters, with relevant violations long remaining unaddressed. This first penalty suggests those days are over.

Maritime operators now face a stark choice: switch to approved alternatives like China’s Beidou navigation system or local cellular networks when approaching Chinese waters, or risk substantial fines, equipment confiscation, potential vessel detention, and costly operational delays. For an industry operating on tight margins and precise schedules, compliance adds yet another layer of complexity to Chinese port calls.

China’s aggressive stance on Starlink extends beyond simple regulatory compliance. Beijing has intensified concerns about the constellation since witnessing its effectiveness in providing battlefield communications during the Ukraine conflict. Chinese military researchers have published numerous papers on potential countermeasures against Starlink, including methods to track and potentially neutralize the satellites.

Meanwhile, China is developing competing domestic satellite internet systems. State-owned China SatNet has launched 60 satellites for its planned 13,000-satellite Guowang constellation, while the Shanghai-backed Qianfan project has deployed 90 satellites toward a 15,000-satellite target. These initiatives underscore Beijing’s determination to maintain autonomous control over critical communication technologies.

The enforcement action also reflects broader tensions over global digital infrastructure. Starlink operates in over 140 countries and has become essential for maritime connectivity worldwide. But in China, along with Russia, Iran, and North Korea, it remains firmly blocked.

Looking ahead, the message for maritime operators from Ningbo is unambiguous: satellite connectivity must bow to sovereignty. With Chinese authorities pledging intensified inspections and enforcement, ship operators calling at Chinese ports should audit their communications equipment now, establish clear protocols for deactivating prohibited systems, and train crews on compliance requirements.

The broader implications extend beyond individual vessels. As satellite internet becomes increasingly integral to maritime operations globally, this enforcement action highlights a fundamental tension between borderless technology and territorial jurisdiction. With trade volumes between China and the rest of the world continuing to surge, expect more vessels to face the choice between connectivity and compliance.

For now, when approaching the world’s busiest ports, going dark isn’t just advisable — it’s the law.
