## Key takeaways

- Taiwan produces around 92% of the world's most advanced semiconductors — making it uniquely strategically valuable
- China claims Taiwan as a breakaway province; Taiwan maintains de facto independence but has no formal UN recognition
- The US maintains "strategic ambiguity" — it neither endorses nor opposes Taiwanese independence, and has committed to supplying defensive weapons
- A conflict over Taiwan would have profound economic consequences given its role in semiconductor supply chains

## The political status

Taiwan (officially the Republic of China) has governed itself independently since 1949, when the Nationalist government retreated there following defeat by the Communist forces on the mainland. The People's Republic of China (mainland China) claims Taiwan as a breakaway province that will eventually be reunified with the mainland — by force if necessary. Taiwan's current government does not accept this framing. The international community maintains an ambiguous position: almost no countries formally recognise Taiwan as an independent state, but most maintain significant unofficial relations.

## The semiconductor dimension

Taiwan Semiconductor Manufacturing Company (TSMC) accounts for around 92% of global production of chips smaller than 10 nanometres — the most advanced, high-performance semiconductors used in smartphones, AI processors, data centres and military systems. No country, not even the United States, currently has the capacity to replicate TSMC's most advanced production lines quickly. This gives Taiwan extraordinary strategic importance: any disruption to TSMC production would cause a global semiconductor shortage with cascading consequences.

## The US position

The United States maintains a policy of strategic ambiguity toward Taiwan: it recognises the PRC as the sole legal government of China (the One China policy) without explicitly endorsing Beijing's claim over Taiwan, and it has committed to providing Taiwan with defensive arms under the Taiwan Relations Act (1979). Whether the US would militarily defend Taiwan against a Chinese attack remains deliberately ambiguous — intended to deter both Beijing (from attacking) and Taipei (from declaring independence).

## The risk scenarios

The risk scenarios range from economic and political coercion short of military action (which has been ongoing) to a military blockade (which would cause a global economic crisis) to an outright invasion attempt (which most analysts regard as militarily very challenging and politically very costly for China, though not impossible). The trend is toward higher tension rather than lower.
