Taiwan, a global revealer.
Taiwan is often referred to as a ‘territorial conflict’. The expression conforts: But this reading grid is no longer enough. Taiwan is less a territory than a thermometer — and sometimes an accelerator—of the tipping over of the world order. What is at stake here goes beyond cartography: It is the legitimacy of powers, the strength of alliances, and the international system’s ability to resist pressure.
The question is therefore no longer whether the Sino-American rivalry will intensify. It is already intensifying, because it is structural: China and the United States are fighting over hierarchy, rules, and value chains. The real question is elsewhere: at what speed and by what mechanisms could this rivalry degenerate—not necessarily through a cold and planned decision, but through successive events, misunderstandings and gears.
Taiwan is not ‘an island’, it’s a credibility test
For Beijing, Taiwan is an existential issue. It touches on sovereignty, historical legitimacy, and the promise of national unity. But it also touches on a more operational dimension: maritime safety. Control its close environment, reduce vulnerabilities, prevent a rival power from transforming the region into a ‘strategic lock’ against China. In this perspective, the status quo is tolerated as long as it does not become a precedent: that of a lasting separation backed by American protection.
For Washington, Taiwan is not only a democracy that one supports: it is essential to the credibility of deterrence. In the Indo-Pacific, allies and partners look less at speeches than at signals: military presence, cooperation, ability to meet costs. Taiwan thus becomes an indirect test for Tokyo, Seoul, Manila, Canberra—and even beyond, for all the capitals that wonder if the American guarantee holds when the pressure rises.
In an international system where power is measured by the ability to enforce red lines, Taiwan acts as a stage where one assesses the solidity of an actor. It is not only ‘who is right’, it is ‘who can impose their version of the order’.
The other reason why Taiwan exceeds the ‘territorial’ is its place in the global economy. The island is at the heart of strategic value chains, particularly in semiconductors. In a world where power is expressed through the mastery of critical technologies, geopolitics mingles with industry. And when the industry gets involved in security, crises do not remain local: they become systemic.
Any serious escalation would not only be a military shock, but a shock of markets, logistics, trust. Even without firing, a partial blockade, threats to sea lanes, or a series of repeated incidents would be sufficient to shift the perception of global risk. Taiwan is thus a point where the Sino-American rivalry turns into ‘global crisis’ almost instantly, because interdependencies amplify everything.
Why the intensification is almost certain?
Rivalry is intensifying as it has become multi-domain. : military, economic, technological, informational, normative. Now, the more domains a rivalry has, the more frictions it produces. Each side interprets the gestures of the other as intentions. Each “defensive” movement becomes, for the opponent, an offensive preparation.
If the rivalry degenerates, it will probably be by cumulative mechanisms, not by an announced ‘grand plan’. We can identify four of them.
1) The incident. A naval collision, an overly aggressive air interception, a misunderstood warning shot.
2) Gradual escalation. Not an immediate invasion, but continuous pressure: exclusion zones, maritime controls, ‘selective’ blockade, cyber attacks, demonstrations.
3) The wrong reading of signals. One believes that the other is bluffing. The other believes that one is preparing a coup. The asymmetry of interpretation.
4) The alliances effect. The more Washington engages, the more Beijing wants to show that it does not give in. The more Beijing demonstrates, the more Washington strengthens. The alliance, designed to stabilize, can paradoxically rigidify and accelerate.
Basically, Taiwan poses a brutal question: does the world accept that a power changes the status quo through pressure, fear, or fait accompli? If the answer is ‘yes’, then the international order becomes fragile because coercion becomes a method. If the answer is ‘no’, then we must pay the price for economic, military and political deterrence.
That is why Taiwan is revealing: it forces everyone to choose, explicitly or not, between immediate comfort and long-term stability. And that’s why the Sino-American rivalry is no longer an abstract debate: it touches on the rules of the game.
Taiwan’s crisis is not inevitable. But its risk increases as rivalry becomes a system. In such a system, peace is no longer a natural state: it is a fragile construct, maintained by the clarity of red lines, the mastery of signals and the ability of each person to avoid strategic pride.
