The 5 Ws
issue overview & course connections
- Where?
- The Taiwan Strait — the body of water separating mainland China (PRC) from Taiwan — with implications for Japan, the East China Sea, and global markets. Taiwan controls over 70% of the world's contract semiconductor market.
- Who?
- The People's Republic of China, the Taiwanese government, the United States, Japan, and international communities dependent on Taiwanese semiconductors.
- When?
- Originated in the Chinese Civil War in 1949; tensions escalated significantly from 2026 onward.
- Why?
- China claims Taiwan as an inalienable part of its territory and views reunification as a historic mission of the CCP. Taiwan's independent national identity and US support directly challenge that goal.
- How?
- Through military intimidation, air incursions, naval exercises, and missile drills, alongside economic sanctions, diplomatic pressure, cyberattacks, and erosion of the median-line status quo in the Taiwan Strait.
Key Stakeholders
People's Republic of China
Claims sovereignty over Taiwan and drives the reunification agenda.
Taiwan Government
Defends democratic sovereignty and self-determination.
United States
Bound by the Taiwan Relations Act; major arms supplier and strategic partner.
Japan
Directly threatened by potential naval expansion; shares territorial disputes with China.
Taiwan Semiconductor Manufacturing Company (TSMC)
Produces 90% of the world's most advanced chips and controls 70% of the global market.
Tech and Manufacturing Industries
Dependent on Taiwanese semiconductors.
Contributing Factors
Social
- ✶A Taiwanese national identity distinct from Chinese identity, especially among younger generations.
- ✶Hong Kong's democracy crackdown increased Taiwanese skepticism toward mainland ties.
- ✶Growing public support for formal independence within Taiwan.
Cultural
- ✶Historical and cultural divide between the Nationalist legacy and the PRC's communist identity.
- ✶Shared ethnic and linguistic heritage paired with distinct political cultures after decades of separation.
Economic
- ✶Taiwan's dominance in global semiconductor production makes it strategically irreplaceable.
- ✶Growing economic interdependence between Taiwan and China creates leverage for Beijing.
- ✶US arms sales worth over $18 billion reflect the economic dimensions of military deterrence.
Political
- ✶The CCP frames reunification as essential to China's national rejuvenation.
- ✶US strategic ambiguity shapes cross-strait calculations.
- ✶China's blocking of Taiwan from international organizations isolates it diplomatically.
- ✶The Taiwan Relations Act legally commits the US to supply Taiwan with defense arms.
Environmental
- ✶Military exercises including live-fire drills and missile launches pose risks to the marine environment.
- ✶Increased naval and air activity contributes to pollution and ecological disruption.
Implications
Social
- ✶People in Taiwan live under constant pressure of potential conflict with China.
- ✶Mass displacement and humanitarian crisis are likely if conflict erupts on a densely populated island.
- ✶Growing militarization increases the risk of escalation affecting civilians.
Cultural
- ✶PRC pressure erodes Taiwan's distinct democratic and cultural identity.
- ✶A forced reunification would extinguish Taiwan's civil society.
- ✶The conflict shapes global debates about self-determination and the rights of small nations.
Economic
- ✶A conflict over Taiwan could cause around $1 trillion in disruption to the global economy.
- ✶Loss of TSMC production capacity would harm global tech supply chains — from iPhones to military hardware.
Political
- ✶A Chinese takeover would shift the Indo-Pacific balance of power and constrain US naval operations.
- ✶Japan's ability to defend its western islands would be compromised if the PLA occupied Taiwan.
Environmental
- ✶Large-scale conflict would cause severe damage to one of the world's most ecologically significant marine regions.
- ✶Prolonged conflict could disrupt international climate cooperation, since China is a critical partner in global emissions agreements.
Bias
Pro-US Bias
Published by the Council on Foreign Relations, a US-based organization. US actions such as arms sales and military training are framed as defensive and stabilizing, while China's equivalent actions are described negatively. A reader is likely to view the US as a neutral protector and China as the main aggressor, without considering Beijing's perspective.
