The Taiwan dossier is back at the centre of global strategic confrontation. As Taipei strengthens its channels with Europe, China intensifies diplomatic and rhetorical pressure, Japan adopts an increasingly tough security language and the United States consolidates military support for Taipei. A complex and accelerated transformation of the balance in theIndo-Pacific is taking place, with implications that go far beyond the Straits.

The big picture: Taiwan between Chinese assertiveness and new international projection

Taiwan is now in a phase of strong international exposure, where diplomacy and security are intertwined in a rather fragile balance. The island, traditionally forced to the margins of international organisations due to the ‘one China‘ principle, is gradually building its own political and strategic room for manoeuvre, especially in Europe.

At the same time, Beijing intensifies its pressure campaigns – military, diplomatic and information – to dissuade any external actor from supporting Taiwan, considering it a key issue for ‘national reunification’. In such a scenario, every international visit, every Japanese declaration, every US arms sale takes on significant symbolic and strategic value, helping to redefine, even constantly, the balance of power in the area.

Hsiao Bi-khim’s mission to Europe: a more assertive and multilateral diplomacy

Vice President Hsiao Bi-khim ‘s visit to the European Parliament represents a qualitative and massive breakthrough for Taiwan’s international projection. According to Euronews, the Taiwanese leader gave an articulate speech, emphasising the need to build stable cooperation with the EU in the areas of cyber security, trade, advanced technologies and democratic defence. She also reiterated that ‘peace in the Strait‘ is a prerequisite for stability in global markets and production chains – particularly semiconductors.

Hsiao then openly called for European support to include Taiwan in international bodies from which it is excluded: WHO, ICAO, Interpol, areas where transnational cooperation is essential. A very clear political message: Taiwan no longer wants to remain on the sidelines of global governance.

The Chinese reaction was immediate and harsh. The Chinese diplomatic mission in Brussels accused the event of grossly violating the ‘OneChina‘ principle (the One China policy, i.e. a diplomatic recognition that there is only one Chinese government, which sees mainland China and Taiwan as part of a single territory) of interfering in internal affairs. The tone of the note denounces Beijing’s growing irritation at any European attempt to broaden dialogue with Taipei.

Beijing-Tokyo: the verbal clash that reveals a deeper strategic conflict

Meanwhile, tensions between China and Japan have escalated following statements by Japan’s newly appointed Prime Minister Sanae Takaichi that a Chinese attack on Taiwan would constitute a ‘threat to survival‘ for Japan. Such a definition, notes The Guardian, activates Japan’s constitutional framework for the right tocollective self-defence – one of the harshest positions Tokyo has ever taken on the Taiwan issue.

China responded by summoning the Japanese ambassador, calling the statements ‘provocative’ and in violation of the ‘one China’ principle. The Korea Times and Global Times report extremely harsh statements by Chinese representatives, with references to Japan’s colonial past and warnings for Tokyo not to interfere in Chinese ‘reunification’.

The situation then escalated further when the Chinese Consul General in Osaka, Xue Jian, published a post on X that read: ‘That dirty neck… must be cut off without hesitation‘. As reported by the Taipei Times, the post was removed but triggered an immediate protest from the Japanese government, which called it ‘outrageous and totally inappropriate’.

This rhetorical escalation reveals a very tense strategic climate, where the Taiwan issue is no longer a bilateral Beijing-Taipei issue, but a dossier directly involving Japanese security.

The US role: continuous military support and balance strategy

On the defence front, the US approved a sale of equipment and spare parts worth around USD 330 million, as reported by Reuters. The package includes essential components for F-16s, C-130s, and indigenous IDF fighters, with the aim of keeping the Taiwanese air fleet operational.

This is the first arms sale to the island under the new Trump administration, and serves as a political signal as much as a military one: Washington wants to ensure that Taiwan maintains an adequate defence capability, without crossing the threshold of direct confrontation with Beijing.

This is part of a broader logic: to ensure that Taiwan remains an essential part of the global semiconductor chain – and thus of US economic interests – while protecting the security architecture in the Western Pacific.

Therefore, the US continues to pursue a strategy of integrated deterrence, supporting Taiwan without reaching a formal recognition that would provoke an immediate crisis with Beijing.

A region on the brink of profound transformation

From the three fronts – Europe, Japan and the United States – some convergent elements emerge:

1. Taiwan as an international player and no longer just a ‘Chinese issue’

Hsiao Bi-khim’s historic visit to the European Commission shows that Taiwan is building its own global profile, based on democracy, technology and secure production chains. Taiwan now wants to be at the centre of the global chessboard, and the EU seems ready to bring the cross-strait issue to Brussels as well.

2. The Beijing-Tokyo axis is more unstable than ever

The rhetoric between the two countries shows how Taiwan is now a central friction point in the regional leadership rivalry. And with the recent installation of PM Takaichi in Japan, relations with Beijing could change dramatically, leading to a sharper line-up of alliances in the Indo-Pacific.

3. Washington confirms itself as the military guarantor of stability

Military supplies and continued strategic support are part of a broader design aimed at deterrence towards Beijing. Even President Trump seems to be very aware that Taiwan cannot be a marginal issue in foreign policy, with Secretary of State Rubio closely monitoring the Taiwan situation.

4. Risk of escalation on several levels

If these trends continue, the Taiwan Strait could become the theatre of the most important geopolitical competition of the decade, involving at least three regional powers and one global power.

Taiwan as the pivot of the new Indo-Pacific architecture

The picture that emerges is that of anEast Asia traversed by rapid transformations, where Taiwan is no longer a mere geographical point halfway between China and the Pacific, but a strategic crossroads around which alliances, diplomatic priorities and power languages are being redrawn. Taipei today represents three fundamental dimensions: a democratic bastion in a context marked by the rise of authoritarian powers, a nerve centre of global semiconductor chains, and a political-diplomatic hub increasingly present on the international scene, despite constant pressure from Beijing.

In this context,Europe attempts to assert its own space of strategic autonomy, using Taiwan as a test of its ability to dialogue with Asian actors without renouncing its democratic values. Japan is moving with a security posture that was unthinkable a few years ago, while the United States is reinforcing its role as regional guarantor. On the contrary, China interprets every sign of openness towards Taipei as a direct threat to its own national objectives, stiffening its tone and rhetoric, as shown by the latest diplomatic clashes with Tokyo and several European representatives.

What is striking is the overlap of levels: economy meets security, diplomacy meets technology, political narrative meets military risk. Taiwan thus becomes a symbol and a proving ground: a symbol of the fragility of democracies in a polarised world, a proving ground to measure how far regional powers are willing to go to preserve – or redefine – the Indo-Pacific, but also global balance.

Despite the uncertainty permeating the region, one thing seems clear: Taiwan is no longer a frozen dossier, nor an issue confined to relations between Beijing and Taipei. It is a barometer of Asian strategic stability, a node of global security, and one of the decisive hubs through which the international order will be defined in the coming years. What is certain is that Taiwan, today more than ever, remains at the centre of the history being written in the 21st century.
