Urgent Analysis

Will a US-China War Happen?

In 2026, the world stands at a crossroads once again. The escalation of US-China relations goes beyond simple economic competition, raising the possibility of military conflict. Are we really on the brink of war?

US-China Relations: Where Are We Now?

As of April 6, 2026, US-China relations are more complex and unpredictable than ever. On the surface, competition and cooperation seem to coexist in various fields such as economy, diplomacy, and technology, but deep-rooted conflicts lie beneath the surface.

In recent years, the United States has been strengthening cooperation with its allies to check China's economic rise and military buildup. In particular, it is putting pressure on China on issues such as the South China Sea, Taiwan, and human rights, and is trying to maintain its competitive advantage in the field of advanced technology.

China is also accelerating its efforts to realize the 'Chinese Dream' in response to US checks. It is expanding its economic influence through the Belt and Road Initiative, promoting military modernization, and strengthening its voice in the international community.

These tensions in US-China relations are not just a problem between the two countries, but have a significant impact on global security and the economy. Each country is struggling to maintain a strategic balance between the US and China, and the international community is concerned about the catastrophic situation that could occur if the US-China conflict intensifies further.

Diagnosing the Possibility of War: 5 Key Factors

In order to objectively assess the possibility of a US-China war, various factors must be considered comprehensively. The following are five key factors that can increase or decrease the likelihood of war.

1. Taiwan Issue: China considers Taiwan a 'core interest' and maintains its position that it will not hesitate to use force to reunify it if necessary. The United States has not clearly stated its defense commitment to Taiwan, but it is checking China by suggesting the possibility of military intervention in the Taiwan Strait.
2. South China Sea Territorial Dispute: China claims most of the South China Sea as its territorial waters, building artificial islands and deploying military bases. The United States does not recognize China's claims and is strengthening its military activities in the South China Sea through freedom of navigation operations.
3. Economic Competition: Economic competition between the US and China is manifested in various forms, including trade disputes, competition for technological hegemony, and currency manipulation. These economic conflicts can act as a factor that increases political and military tensions between the two countries.
4. Technological Hegemony Competition: Competition between the US and China in advanced technology fields such as artificial intelligence, 5G, and semiconductors is intensifying. The United States is taking various measures such as Huawei sanctions and export controls to check China's technological rise, and China is also trying to break away from US influence through its own technology development.
5. Domestic Political Factors: Domestic political situations in both the United States and China have a significant impact on foreign policy. In the case of the United States, a hard-line stance against China is gaining political support, and China is also stimulating nationalistic sentiments to strengthen internal unity.

Expert Analysis: The possibility of a US-China war can vary greatly depending on the interaction of the factors mentioned above. In particular, the Taiwan issue and the South China Sea territorial dispute are highly likely to lead to accidental clashes, and economic and technological competition can act as factors that deepen long-term conflicts.

Scenario-Based Outlook: War Outbreak Scenarios and Deterrence Scenarios

How likely is a US-China war to actually occur? Let's analyze the possibility of war and deterrence measures in depth through various scenarios.

War Outbreak Scenarios

• Taiwan Strait Crisis: If China invades Taiwan by force, the United States is likely to intervene militarily to defend Taiwan. In this case, it could lead to a full-scale war between the US and China.
• South China Sea Clash: If an accidental clash occurs between US and Chinese warships in the South China Sea, tensions between the two countries could escalate and expand into military conflict.
• Cyber ​​Attack: If China launches a cyber attack on the core infrastructure of the United States, the United States may launch a retaliatory attack on China, which could lead to a cyber war.

War Deterrence Scenarios

• Strengthening Diplomatic Efforts: The US and China should strengthen efforts to promote mutual understanding and resolve misunderstandings through high-level talks, summit meetings, etc.
• Building Military Trust: The US and China should increase military transparency and establish a military trust-building mechanism to prevent accidental clashes.
• Strengthening International Cooperation: As responsible members of the international community, the United States and China should cooperate to solve global problems such as climate change and pandemics.

Caution: A US-China war could have devastating consequences beyond imagination. Terrible scenarios such as the possibility of using nuclear weapons, global economic collapse, and large-scale casualties could become a reality.

Future Outlook: Where Are US-China Relations Heading?

How will US-China relations unfold in the future? As of 2026, it is very difficult to predict the future, but we must keep some possibilities in mind and prepare for them.

• New Cold War Era: Competition between the US and China may intensify further, and a new Cold War era may arrive, in which the world is divided into a US-centered camp and a China-centered camp.
• Limited Cooperation Era: The US and China may continue a limited cooperation era in which they pursue competition and cooperation in parallel, cooperating in certain fields but continuing conflicts in fields related to core interests.
• Multipolarization Era: The influence of the United States may weaken, and other powers such as China, Europe, and India may rise, leading to an era in which the world becomes multipolarized.

Whatever scenario becomes a reality, we must not let our guard down regarding changes in US-China relations and must actively respond. Individuals, businesses, and governments must all establish strategies for the future and prepare to respond flexibly to change.
