From the Pelosi visit through military escalation, tech decoupling, and the new great-power competition. A research overview of the most dangerous flashpoint in the world.
From the Pelosi visit through escalating military exercises, elections, summits, and the trade war spiral.
House Speaker Pelosi visits Taiwan -- the highest-ranking US official since 1997. China responds with unprecedented live-fire exercises in six zones encircling Taiwan, launching 11 ballistic missiles and deploying 100+ warplanes. The de facto median line in the Taiwan Strait is effectively erased. China suspends eight channels of bilateral dialogue with the US.
PLA conducts three-day exercise following Tsai Ing-wen's meeting with House Speaker McCarthy. 91 aircraft and 12 ships detected in a single 24-hour period. Symbolic encirclement continues the pattern established in 2022.
At the APEC summit, Biden and Xi restore military-to-military communications (suspended since Pelosi), agree to cooperate on fentanyl, and establish AI safety channels. Xi commits to no interference in 2024 US elections.
DPP wins an unprecedented third consecutive presidency with 40% of the vote. Beijing labels Lai a "dangerous separatist." Within days, Nauru switches recognition to Beijing, reducing Taiwan's diplomatic allies to 12. China alters aviation routes near the median line.
Three days after Lai's inauguration, China launches expanded exercises. Coast Guard operates alongside PLA for the first time in this context. 111 aircraft and 46 naval vessels deployed. Blockade and port-seizure rehearsals.
Single-day exercise in response to Lai's National Day speech. Record single-day ADIZ incursions. The exercise features multi-service operations and integrated Coast Guard involvement -- a grey-zone tactic also used in the South China Sea.
Trump launches aggressive tariff campaign. 20% fentanyl tariffs in February, 34% "reciprocal" tariffs in April, escalating to 145% after retaliatory spirals. US tariffs reach highest levels in over a century. May ceasefire brings rates back to 10%.
Supreme Court unanimously upholds the TikTok divestiture law. TikTok briefly goes dark before Trump delays enforcement. Over the course of 2025, a deal is negotiated: Oracle-led consortium acquires 80% of TikTok's US operations. Deal closes January 2026.
PLA exercise targets Matsu Islands and central Taiwan Strait. Focuses on "identification, warning, expulsion, interception, and detention" -- blockade enforcement capabilities. 135 aircraft sorties, 38 naval vessels.
100-minute meeting produces a tariff reduction framework. China agrees to increase soybean purchases and release rare earth licenses. Tariff truce extended through November 2026. Both sides signal continued engagement.
PM Takaichi suggests JSDF could deploy in a Taiwan contingency. Beijing reacts sharply. The crisis further internationalizes the Taiwan issue and contributes to triggering China's largest-ever military exercises.
China's largest military exercises around Taiwan to date. 130 aircraft, 90+ ships, live-fire rockets near Taiwan's contiguous zone. Triggered by the record $11B US arms sale and the Japan crisis. Simulated blockade with parallel ship formations east of Taiwan.
Tensions remain elevated but no open conflict. Trump plans April Beijing visit. Supreme Court struck down IEEPA tariffs in February, forcing legal restructuring. New Section 301 investigations launched. ADIZ incursions dropped 42% in early 2026 -- significance debated.
Deterrence won't fail in the Taiwan Strait -- it will be bypassed.War on the Rocks, February 2026
PLA build-up, exercise escalation, Taiwan's defence reforms, and the military balance across the Strait.
The Eastern Theater Command controls substantial ground, naval, air, and rocket forces. The PLAN is the world's largest navy by hull count. Key assets include 30+ destroyers, 50+ amphibious ships (growing to 70+ by 2030), three Type 075 LHDs, and the next-generation Type 076 with electromagnetic catapult (sea trials November 2025). Six Amphibious Combined Arms Brigades are dedicated to Taiwan operations. In 2025 exercises, the PLA practised with civilian vessels to augment sealift.
Approximately 900 SRBMs can strike Taiwan with minimal warning. The DF-17 hypersonic glide vehicle is now widely deployed near Taiwan -- extremely difficult to intercept. The DF-21D and DF-26 "carrier killer" anti-ship ballistic missiles target US carrier groups. Estimated 360 DF-17 HGVs, 480 DF-21D missiles, and ~400 ground-launched cruise missiles in the Eastern Theater. Strike range covers 1,500-2,000 nautical miles. Note: PLARF experienced significant leadership purges in 2023-2024 over corruption.
Shifting to an asymmetric "porcupine strategy" -- mobile anti-ship missiles, mines, drones, small stealth corvettes. Defence spending rising to 3.3% of GDP (2026), targeting 5% by 2030, with a $40B supplementary budget. Conscription extended to one year (2024), though only 6% uptake. The Hai Kun indigenous submarine completes trials mid-2026. Missile production two years ahead of schedule. December 2025 US arms sale: $11.15B including 82 HIMARS, 420 ATACMS, 60 howitzers, Javelins, and drones.
The Taiwan Relations Act provides the legal basis for arms sales but doesn't commit the US to intervene. In practice, policy has shifted: the 2025 NSS lists "deterring a conflict over Taiwan" as an explicit priority. $39B+ in arms sales notified 2015-2025. Regional buildup includes Typhon mid-range missiles in Japan and Philippines, island airfield rehabilitation across Micronesia, and 500+ joint activities with the Philippines in 2026.

Semiconductor controls, Huawei's breakthrough, the tariff spiral, TikTok, rare earths, and the messy reality of decoupling.
Since October 2022, the US has imposed escalating restrictions on advanced chip exports to China -- the most significant technology controls since the Cold War. Key milestones: October 2022 sweeping controls, October 2023 loophole closures, 2025 Trump expansion (65+ entities blacklisted), January 2026 shift to case-by-case review. The Netherlands and Japan restricted ASML and Tokyo Electron sales. As of early 2026, the administration is recalibrating ahead of the Beijing summit. A CNAS analysis identified multi-patterning as a significant loophole.
$52.7B allocated. TSMC Arizona Fab 1 entered production (4nm, early 2025); Fab 2 targets 2nm by 2027. Intel's Fab 52 achieved high-volume 1.8nm production -- the first US sub-2nm fab. Samsung's Taylor, Texas facility targets 2nm GAA late 2026. Intel's Ohio fabs delayed to 2027-28. Whether the Trump administration sustains funding remains uncertain.
Huawei's Mate 60 Pro (August 2023) shocked analysts: a 7nm chip produced entirely by SMIC without EUV lithography. The Mate 80 Pro Max (late 2025) featured the more advanced Kirin 9030. SMIC is pushing toward 5nm using multi-patterning. China's self-sufficiency rate: ~25%, well short of the 70% MIC2025 target. Export controls are slowing but not stopping Chinese advancement.
Trump's second-term tariffs peaked at 145% on China in April 2025 -- the highest US tariff levels in over a century. China retaliated with 125%, rare earth restrictions, and agricultural cutoffs. Impact: US imports from China halved by June 2025; China's share of US imports fell to ~7% (from 20%+ pre-2018). The May 2025 ceasefire and November framework brought rates to ~10%. The Supreme Court struck down IEEPA tariffs in February 2026. New Section 301 investigations launched March 2026.
China controls 60-70% of rare earth mining and 85%+ of processing. In April and December 2025, Beijing imposed export license requirements with extraterritorial provisions -- targeting any company affiliated with foreign militaries. Temporarily suspended under the November 2025 truce. US diversification efforts (Ucore, Energy Fuels, Noveon Magnetics) are underway but 5-10 years from replacing Chinese supply at scale.
Full decoupling has not occurred. What's emerged is selective decoupling in strategic sectors (advanced chips, AI, quantum, defence materials) alongside diminished but continuing consumer trade. China's share of US imports fell from 20%+ to ~7%, but imports shifted to Vietnam, Mexico, and India -- some serving as transshipment points. Cross-border VC flows collapsed. The EU favours "de-risking" but moves more slowly. The IMF estimates large-scale de-risking could cost 4.5% of global GDP.
Alliance building, South China Sea confrontations, the One China policy, and Beijing's diplomatic toolkit.
The trilateral pact centres on providing Australia with nuclear-powered submarines. Design review expected September 2026. Australia committed A$13.6B; the UK pledged GBP 8B. But the programme faces severe strain: no Royal Navy SSNs were at sea in late 2025, and analysts describe the deal as potentially "on life support." Pillar II (AI, quantum, hypersonics) may deliver more near-term value.
The most significant military buildup since WWII. Record $58B defence budget for FY2026 (fourth consecutive increase). Developing 1,000km Type-12 standoff missiles and the SHIELD unmanned coastal defence system. PM Takaichi stated Japan's military could intervene in a Taiwan contingency -- the most direct statement from a Japanese leader on this issue. Japan is on track to become the world's third-largest defence spender.
Evolved from informal grouping to structured partnership. 2025-2026 saw Foreign Ministers meetings, counterterrorism cooperation, Ports of the Future Partnership, and the first Quad-at-Sea observer mission. India maintains a more cautious posture, resisting anti-China framing. The Quad's value lies in diplomatic signalling and practical cooperation rather than hard military deterrence.
Fastest-growing bilateral military relationship in the region. Nine EDCA sites including bases near the South China Sea and Taiwan Strait. $144M new EDCA investment. 500+ joint activities in 2026. Typhon and NMESIS missile systems deployed to Batan Island -- 150km south of Taiwan. Manila's warning: Filipino deaths in the South China Sea would be a "red line" triggering the Mutual Defense Treaty.
Second Thomas Shoal remains the most dangerous friction point. Escalation from water cannons and lasers (2023) to ramming and boarding with weapons (June 2024 -- a marine lost his thumb). A provisional agreement in July 2024 reduced tensions temporarily. China also confronted the Philippines at Scarborough Shoal (ramming, August 2025). The US conducted FONOPs at Scarborough (first since 2019) and the Paracels.
The US acknowledges but does not accept the PRC's claim. The PRC insists Taiwan is an "inalienable part" of China. This gap is enormous -- covering sovereignty, use of force, arms sales, and diplomatic relations. The Trump 2025 NSS conspicuously omits the words "one China." Taiwan has only ~12 formal diplomatic allies remaining. The framework endures because its ambiguity serves all parties -- but strain is increasing.
Wolf warrior diplomacy is evolving, not disappearing -- selectively applied, especially toward Japan. Economic coercion is primarily reactive (Stimson Center). Beijing systematically reduces Taiwan's diplomatic partners through investment incentives to small states. Framing: sovereignty/internal affair, inevitability of reunification, blame on "separatists" and "external forces." Increasing attention to Global South narratives where perception of waning US support for Taiwan may grow.
What experts actually think about conflict probability, deterrence dynamics, economic restraints, and indicators to watch.
CFR rates Taiwan as the world's most dangerous flashpoint, with ~50% chance of a crisis in 2026. Against this: 83% of CSIS-surveyed China experts reject kinetic action by 2027; 85% of Defense Priorities respondents call invasion "unlikely." The Stimson Center argues Beijing prefers peaceful reunification. An increasingly influential middle view: the real threat is grey-zone escalation, not invasion. The honest answer: no one knows the probability with precision.
CSIS invasion wargame (24 iterations): Taiwan survives in most scenarios but at enormous cost -- US loses 2+ carriers, hundreds of aircraft. Requires: Taiwan ground forces holding beachheads, US access to Japanese bases, long-range anti-ship missiles, immediate US intervention. CSIS blockade wargame: "escalatory pressures difficult to contain." RAND's nuclear analysis: escalation to nuclear use "cannot be reduced to zero." The deterrence gap: Western thinking is invasion-centric, but China may pursue coercion below the threshold of war.
Taiwan produces 90%+ of advanced chips (3nm/5nm). TSMC controls ~70% of foundry revenue. Bloomberg estimates conflict could cost $10.6 trillion globally (-9.6% of world GDP). But the "silicon shield" is eroding: US Commerce Secretary called for "50-50 production split," TSMC is building in Arizona, and China invests heavily in domestic capacity. The shield's deterrent value is strongest 2025-2028 and weakens as alternatives come online. Economic interdependence restrains but cannot guarantee peace.
Military: Unusual PLA mobilization, forward missile deployment, civilian shipping activation, increased submarine patrols. Political: Rhetoric beyond established formulas, diplomat recalls, CMC emergency sessions, "liberation" language replacing "peaceful reunification." Economic: Chinese commodity stockpiling, capital flight, pre-positioned economic warfare measures. Grey zone: Coast guard boarding commercial vessels, undersea cable cuts, critical infrastructure cyber attacks, fishing militia formations. Positive: Restored military comms, reduced exercises, cross-strait agreements.
Five structured frameworks for how the situation could evolve, ranked by assessed likelihood.
China intensifies pressure through military exercises, ADIZ incursions, coast guard operations, cyber attacks, and economic coercion. The 2022-2025 pattern continues with gradual escalation but no kinetic threshold crossed. Risk: accidents or miscalculation could trigger unintended escalation.
China uses coast guard and naval forces to "inspect" commercial shipping, framed as law enforcement. Taiwan has <2 months of coal/gas reserves. CSIS: even 50% trade curtailment would prove "detrimental." Exploits the ambiguity between enforcement and warfare, complicating US response.
Missile strikes on military targets or seizure of offshore islands (Kinmen/Matsu, Pratas) as a fait accompli. Plausible as response to a perceived provocation. Risk: any kinetic action dramatically increases probability of full-scale war through escalation dynamics.
Joint island landing campaign -- amphibious assault, airborne ops, missile bombardment. CSIS: China likely fails to sustain beachheads in most scenarios, but at catastrophic cost to all. No comparable amphibious operation has succeeded in modern warfare. Requires multiple conditions to align simultaneously.
The status quo has been maintained for 75+ years. Diplomatic frameworks, cross-strait economic integration, or internal Chinese political shifts could sustain peace. The Quincy Institute argues for "supporting Taiwan without a commitment to war." Domestic politics on all sides constrain flexibility.
