Dutch Warship Completes Taiwan Strait Transit — China Responds With Naval and Air Surveillance

.

Dutch Frigate Enters the Taiwan Strait

The Royal Netherlands Navy frigate HNLMS De Ruyter transited the Taiwan Strait on Friday, June 5, 2026, prompting a swift response from China's military. The People's Liberation Army Eastern Theater Command (PLA ETC) announced it had deployed both naval and air assets to track and monitor the Dutch warship throughout its passage.

In a formal statement, PLA spokesperson Xu Chenghua said the situation was handled "effectively." He added that Chinese forces "will stay on high alert at all times and resolutely safeguard China's sovereignty and security, as well as regional peace and stability." The Dutch navy did not immediately respond to requests for comment.

A Repeat Confrontation — Just Days After the South China Sea Incident

The Taiwan Strait transit comes directly on the heels of a more confrontational episode. On May 27, HNLMS De Ruyter sailed near the Paracel Islands in the South China Sea — a disputed island group controlled by China but also claimed by Vietnam and Taiwan. Beijing reacted forcefully, deploying warships, a fighter aircraft, and reportedly using electronic interference measures to push the Dutch frigate away from the area.

China accused the vessel of violating its territorial waters and airspace, claiming the ship's NH90 helicopter had conducted multiple unauthorized sorties over Chinese-controlled territory. The Netherlands firmly rejected these claims. Dutch officials stated that the frigate "has not been in territorial waters" and operated entirely "in accordance with international law."

HNLMS De Ruyter is a 6,000-ton, air-defense frigate currently on a global circumnavigation. It had recently made a port call in Manila, and is set to participate in the 2026 RIMPAC (Rim of the Pacific) military exercises involving 31 nations — the world's largest international maritime war game.

Who Controls the Taiwan Strait? A Disputed Question

At the heart of the incident is a fundamental disagreement about who controls the waters of the Taiwan Strait.

Beijing considers the strait to be Chinese territorial waters, based on its assertion that Taiwan is an inseparable part of China. Under this view, foreign warships are required to seek prior permission before transiting. The PLA ETC's deployment of tracking forces is consistent with that position.

The international community — including the European Union, the United States, and most NATO members — takes a different stance. Under the United Nations Convention on the Law of the Sea (UNCLOS), the Taiwan Strait qualifies as an international waterway used for global navigation. This gives all vessels, including warships, the right of unimpeded transit passage. The strait connects the East China Sea and the South China Sea and is roughly 220 nautical miles wide at its broadest point, well beyond any single state's territorial claim.

Legal analysts note that UNCLOS Articles 37 and 38 explicitly guarantee freedom of navigation and overflight in straits used for international navigation — regardless of a coastal state's territorial claims.

Europe Asserts Its Presence in the Indo-Pacific

The HNLMS De Ruyter's mission reflects a broader shift in European foreign policy. Several European navies — including those of France, Germany, and the United Kingdom — have in recent years begun conducting regular Indo-Pacific patrols to signal support for freedom of navigation and a rules-based international order.

This is not the first time a Dutch warship has faced pressure from China. In 2024, a different Netherlands frigate, HNLMS Tromp, was circled by Chinese fighter jets during a mission to enforce international sanctions against North Korea — an incident the Dutch defense ministry described as "potentially unsafe."

The current deployment of the De Ruyter represents a deliberate political signal: European democracies are not willing to cede the Indo-Pacific to unilateral Chinese control.

Beijing's Expanding Territorial Claims — and the Risks Ahead

China's aggressive tracking of the Dutch frigate is part of a well-established pattern. Beijing has consistently challenged foreign naval transits through both the Taiwan Strait and the South China Sea, using military maneuvers, electronic interference, and diplomatic protests as tools of deterrence.

The PLA Eastern Theater Command, which issued Friday's statement, is also the command responsible for any potential military operation against Taiwan. Its repeated declarations about "safeguarding sovereignty" are closely watched by Western defense analysts as indicators of Chinese military intent.

As European navies become more active in the region and Beijing doubles down on territorial assertions that most of the world does not recognize, confrontations like the one involving HNLMS De Ruyter are likely to become more — not less — frequent.
