Taiwan's Coast Guard Administration said on Sunday, Oct. 18, 2026, that it confronted and drove away 16 Chinese coast guard, research and fishing vessels in simultaneous operations around Taiwan's main island and the Taiwan-held Pratas Islands, calling the activity "hybrid warfare". The incidents unfolded overnight into Sunday, and all the Chinese ships had left Taiwan's restricted waters by about noon local time Sunday (midnight ET), according to a detailed account of the coast guard statement.
The coast guard said Beijing was "attempting to unilaterally alter the status quo" and said it "condemns them in the strongest terms." Some of the vessels entered waters Taiwan restricts, off the island's east, south and southwest coasts and around Pratas, known in Taiwan as Dongsha.
The Taiwan Strait gray-zone pressure campaign is the latest test of how far China will push its claim to "jurisdiction" over waters Taiwan controls, and it comes less than three weeks after Taiwan used a water cannon on a Chinese fishing boat near Pratas.
Key Facts
- When: Overnight into Sunday, Oct. 18, 2026, ending about noon Taiwan time (UTC+8), or about midnight ET.
- Where: Waters off eastern, southern and southwestern Taiwan, including east of Hualien, southwest of Eluanbi and southwest of Kaohsiung, and around Pratas (Dongsha) Island in the South China Sea.
- Who: Taiwan's Coast Guard Administration (CGA) against China Coast Guard cutters, Chinese research ships and fishing boats.
- How many: 16 Chinese vessels, including 12 coast guard, research and other ships and four fishing boats, according to the CGA.
- Military picture: Taiwan's defense ministry separately tracked 2 Chinese military aircraft, 5 naval vessels and 9 "official ships" in the 24 hours to 6 a.m. Sunday.
- Status: Reported in Taiwan's coast guard statement and multiple wire reports; Beijing had not responded publicly to this incident.
What Happened
The CGA said its ships took "forceful action immediately to effectively neutralise the threats" and accused Beijing of trying to give a "false impression of jurisdiction." Another line in the statement warned that "such actions will only lead to resentment among the people of Taiwan," according to WION.
A detailed account of the coast guard statement published by The Eastern Herald names several of the ships. At Pratas, China Coast Guard cutters 3301 and 3303 circled the island until Taiwanese coast guard ships Qijin and Taichung shadowed them out.
Off eastern Taiwan, a patrol boat from the CGA's Taitung unit broadcast orders for the Chinese research ship Tansuo-3 to leave restricted waters east of Hualien, the outlet reported. Southwest of Eluanbi, Taiwan's southern tip, the research ship Beidiao 996 entered restricted waters after midnight and left only after a Hengchun unit patrol boat warned it 12 times.
Southwest of Kaohsiung, a Chinese research ship and a steel-hulled Chinese fishing boat interfered with the Taiwanese fishing boat Wan Fa Cheng 11, and the coast guard ship Pingtung moved in to protect it, according to the same account. Ecker Geopolitics could not independently verify the ship-by-ship details, which have not been carried in full by the international wires.
The CGA described the tally as an "abnormal increase" but did not say how it arrived at the count of 16. Chinese warships, which operate near Taiwan almost daily, are counted separately.
The military picture was quieter. Taiwan's Ministry of National Defense reported 2 People's Liberation Army aircraft, 5 naval vessels and 9 official ships around Taiwan between 6 a.m. Saturday and 6 a.m. Sunday. Both aircraft crossed the Taiwan Strait median line into Taiwan's northern and central air defense identification zones, and Taiwan deployed aircraft, naval ships and coastal missile systems to monitor them.

Who's Involved
- Coast Guard Administration (Taiwan): Handles day-to-day security at Pratas and led Sunday's response; it calls the operations hybrid warfare and "fake law enforcement, real expansion."
- China Coast Guard: Operated cutters 3301 and 3303 around Pratas, according to the CGA account.
- Chinese research ships Tansuo-3 and Beidiao 996: Entered restricted waters east and south of Taiwan, according to the CGA account.
- Ministry of National Defense (Taiwan): Tracks PLA aircraft and naval activity separately from coast guard incidents.
- Chen Binhua, spokesperson for China's Taiwan Affairs Office: Said after the water cannon incident that China has "indisputable sovereignty" over Pratas and that Chinese vessels there are "entirely legal and justified."
- Lii Wen, deputy secretary-general of Taiwan's National Security Council: Said China is using a wider range of ships, including militia boats and research vessels, in gray-zone operations.
The OSINT Picture
Pratas sits roughly between southern Taiwan and Hong Kong, more than 400 kilometers from Taiwan. It is a national park with an airstrip and no permanent civilian population, and security experts consider it vulnerable because of that distance.
The data trend is the clearest open-source signal. Taiwanese official figures reported by AFP show Chinese coast guard, research and other ships around Taiwan's main island jumped from 30 in May and 55 in June to a record 244 in July. Taiwan News, citing the defense ministry, reported that so far in October Taiwan has tracked Chinese aircraft 115 times and ships 208 times.
Research ships matter for a military reason. Analysis: survey vessels can map seabed and water conditions that submarines rely on, which is why Taiwan's coast guard shadows them. In June, China's Ministry of Natural Resources said the research ship Xiangyanghong 22 had spent three days on what it called a marine environmental survey in waters east of Taiwan.
Video of the Oct. 1 water cannon incident near Pratas, posted by Focus Taiwan (CNA English News), shows how these encounters typically unfold.

In that case, the patrol boat Yunlin fired its water cannon for about 30 seconds from roughly 200 meters, then for 90 seconds at closer range, Maritime Executive reported. The Chinese boat later lost power and was towed out of Taiwan's waters.
Geopolitical Players
China claims Taiwan, Pratas and the surrounding waters, and Taipei rejects those claims. After the water cannon incident, Beijing's Taiwan Affairs Office accused Taiwan of "maliciously stirring up cross-strait confrontation" and said it must "bear all consequences," without saying what those would be.
Taiwan says it acts carefully. A Taiwanese official told Reuters the coast guard conducted "normal law enforcement" in a "very careful and proportionate way." President Lai Ching-te has tied record defense spending to deterrence, as covered in our report on Lai's National Day pledge to "deter war".
The PLA keeps up its own pressure. The same week as Beijing's warning, Taiwan's defense ministry reported a "joint combat readiness patrol" involving 13 aircraft, including J-16 fighters, and China said the carrier Liaoning was drilling in the western Pacific.
What It Means for the United States
Benefits and opportunities
- Allied resolve on display: Taiwan's coast guard is pushing back without firing weapons, which supports the U.S. goal of deterrence without war.
- Coast guard cooperation: Analysis: China's use of coast guard and research ships, rather than warships, strengthens the case for U.S. coast guard training and maritime-awareness support for Taiwan and the Philippines.
- Intelligence value: Repeated Chinese patterns around Pratas and eastern Taiwan give U.S. and allied planners more data on how Beijing might stage a quarantine.
Risks and dangers
- Quarantine rehearsal: Analysis: coordinated coast guard "law enforcement" around an outlying island looks like practice for a blockade or quarantine that could stop short of war but still cut supply lines.
- Pratas as a flashpoint: A remote island defended by coast guard rather than military forces is a tempting target, and a seizure would test U.S. commitments without directly touching Taiwan's main island.
- Supply chains: Analysis: Taiwan is central to the advanced-chip supply that U.S. technology and defense industries depend on, so any escalation in the Taiwan Strait carries direct economic risk.
- Two-theater strain: Analysis: the U.S. Navy is heavily committed to the Middle East during the Strait of Hormuz crisis, which could tempt Beijing to probe in the Pacific.

What's Next
Beijing has not publicly responded to Sunday's operation. Analysis: the CGA's own tally points to steady pressure at Pratas: 11 expulsions across 14 passages this year before Sunday, according to an Oct. 16 CGA figure.
Watch Taiwan's daily defense ministry reports and coast guard statements for whether the multi-front pattern repeats, and for any Chinese announcement of new "law enforcement" patrols around Pratas.
