What we know about China’s military exercises around Taiwan; and what the blockade claims get wrong

What did the viral map claim; and what actually sailed?

A map shared widely on social media this week appeared to show the end of Taiwan as an open island: dozens of Chinese warplanes lifting off from the mainland and circling the island, dozens of warships closing into an airtight ring around it. France 24’s Observers unit examined the claim on Friday 13 November and found that it misreads what China’s forces have actually done around Taiwan since early November.

What is real is a large, unannounced deployment. Since 2 November, China has operated naval forces across the western Pacific and around Taiwan in an exercise it never announced or named. Taiwan’s National Security Council said on 3 November that more than 100 Chinese navy and coast guard vessels were at sea in the region, and Taiwan’s defence ministry counted 49 Chinese military aircraft near the island in 24 hours, the highest daily figure of the year. What is not real is the blockade the map implies. No blockade has been imposed, civilian shipping has continued, and the numbers tell against the claim: over 8–9 November, Taiwan’s military counted a single Chinese aircraft north of the island and eight ships nearby. Eight ships cannot organise a blockade, as the analyst Emmanuel Véron of HEC Paris told France 24.

What do the counts, the map and the ministries actually show?

The picture is built from three kinds of evidence, and they agree on the scale. First, the counts. On 3 November, Joseph Wu, secretary-general of Taiwan’s National Security Council, published a map on X and said more than 100 navy and coast guard hulls were at sea across the region. The same day, Taiwan’s defence ministry recorded 49 sorties by Chinese military aircraft around the island in 24 hours. Second, the geography. The deployment drew coordinated forces from China’s eastern, northern and southern theatre commands, according to a senior Taiwan security official, with the Liaoning carrier strike group in the Philippine Sea and the Fujian, China’s newest carrier, observed separately in the South China Sea.

Third, the official confirmations. Defence Minister Wellington Koo said this week that China is conducting ‘area denial’ drills in the western Pacific involving an aircraft carrier and other naval formations. A senior Taiwan security official also said the drills included simulated attacks on foreign militaries and cities in Taiwan, and a submarine-launched intercontinental ballistic missile from the Yellow Sea. The deployment was larger than Justice Mission 2025, China’s last formally named drills aimed at Taiwan nearly a year ago. By Friday the scale had eased: about 70 vessels were operating inside the first island chain, two Taiwan security officials said, though Wu added late on Thursday that the theatre-command groups and the Liaoning group remained at sea, and air activity stayed high. Readers following the earlier deployment can compare the two moments in our report on the unannounced Pacific drills.

What has no one published, or been able to prove, about the operation?

Almost everything that would turn a deployment into a legible operation. China has given the exercise no name, no stated start, no stated end and no stated purpose as a whole. Its defence ministry did not respond to a request for comment from Reuters, and its only public characterisation of the carrier’s movements is that they are routine training, not directed at any particular country. That silence leaves the central question open: are the forces at sea one coordinated exercise, or several overlapping deployments that happen to coincide? The Institute for the Study of War raised on 6 November the possibility that China is running a large undisclosed exercise simulating the isolation of Taiwan, but the reporting so far does not establish that every deployment belongs to a single operation.

Nor is the missile claim independently confirmed. The account of a submarine-launched intercontinental ballistic missile fired from the Yellow Sea rests on a single senior Taiwan security official, and no type, range or purpose has been published. What the record establishes is the shape of the deployment and its scale; what it does not establish is Beijing’s intent, the operation’s end date, or whether the next peak will be larger than the last.

Why does an unannounced exercise carry more weight than a named one?

Named drills come with warnings, dates and a script the region can read. This one came with none of that, and the absence is the message. Taipei’s officials have called the campaign ‘silent intimidation’, a phrase that captures the logic: pressure visible enough to be counted on a map and deniable enough to be described as routine training. The deployment was larger than anything China has aimed at Taiwan in a year, it rehearsed the geography of encirclement without ever imposing it, President Xi Jinping gave a major policy speech on Taiwan on Thursday, urging peaceful reunification and making no mention of using force; the political line running alongside the military signal.

The stakes are wider than the strait. Taiwan sits at the centre of the world’s semiconductor supply chain and astride some of its busiest shipping lanes, so the difference between a simulated blockade and a real one is the difference between pressure and a global economic shock. That is why the debunk matters as much as the deployment: a viral map claiming a blockade can move markets, moods and military planning before anyone checks the ship count. The question now carried into the Manila meetings; where Quad leaders are arranging their first summit in over two years; is whether unannounced deployments at this scale are becoming the new normal.

What does the exercise rehearse; and what does it not prove?

The strongest evidence in this story is also the most limited: the numbers prove scale, not intent. More than 100 vessels, three theatre commands, two carriers and 49 sorties in a day prove China can mass a very large force across a wide stretch of sea without announcing anything. They do not prove that the force was assembled to blockade Taiwan, and the movement of the numbers argues against that reading. A blockade is a condition, not a spike: it has to persist, close the sea lanes and stop civilian shipping. This deployment peaked on 3 November, fell to a single aircraft and eight ships near the island by 8–9 November, and eased to about 70 vessels by Friday; while civilian shipping continued throughout. That is the signature of a rehearsal and a signal, not of a siege.

What the rehearsal demonstrates is a capability that matters even if the intent stays ambiguous: coordinated operations across three theatre commands, a carrier group in the Philippine Sea, coast guard hulls ringing the island and a missile launch from a submarine, all without a name or a notice. The ambiguity is the instrument. It forces Taipei, Washington and the region to respond to a deployment Beijing calls routine.

What follows if the drills recur; and if the numbers keep falling?

First, the calendar. If unannounced deployments of this size recur without a name or a notice, the region’s militaries will have to treat every large Chinese sailing as a potential exercise, raising the cost of vigilance and the chance of a misread encounter at sea. Second, the economics. Shippers and insurers price risk on patterns, not intentions: a second unannounced massing would push freight and war-risk premiums up even if no shot is fired. Third, the diplomacy. The drills landed in the week of the Manila meetings and ahead of the Trump–Xi encounter, and the pattern of pressure-then-summit is now familiar enough that both sides will read the other’s moves as messages; which is how miscalculation happens. The wider great-power contest around these waters is the subject of our look at whether the United States, Russia and China are racing for position.

What should we watch in the waters east of the Philippines?

Watch the counts, day by day. Taiwan’s defence ministry publishes daily figures on Chinese aircraft and vessels, and Joseph Wu has posted updates on X through the week, including on Thursday night. If the daily sorties settle below about 20 for two consecutive days, the deployment is dispersing; if they spike again towards 49, it is sustaining. Watch the carriers, watch for a name, if Beijing ever names the operation, the exercise stops being deniable, and watch what the Manila summits and the Trump–Xi encounter produce on Taiwan.
