Why Japan Faces China’s Rising Threat?

Tensions between China and Japan have reached a critical juncture, with China’s military maneuvers near the Senkaku Islands (Diaoyu to China) and Japan’s southern EEZ sparking global concern. Recent reports, including X posts and analyses highlight China’s deployment of the Liaoning and Shandong aircraft carriers, coupled with a near-miss incident involving a Chinese jet and a Japanese patrol plane.

The Motive Behind China’s Threats

China’s assertive posture toward Japan is driven by a mix of territorial ambitions and strategic imperatives. The Senkaku/Diaoyu Islands, administered by Japan but claimed by China, hold significant reserves of oil, natural gas, and fisheries, making them a key economic and strategic asset. X posts from June 12, 2025, note China’s carrier group movements within 200 nautical miles of Japan’s EEZ, signaling a deliberate challenge to Tokyo’s control. Beyond resources, China aims to undermine the U.S.-Japan security alliance, which includes 54,000 U.S. troops, and weaken regional opposition to its Taiwan unification agenda. Beijing’s recent economic sanctions, such as banning Japanese seafood imports over Fukushima wastewater, further illustrate its intent to pressure Japan on multiple fronts.

The China-Japan rivalry extends beyond territorial disputes, offering a multifaceted view of the escalating tensions:

1. Territorial and Resource Disputes: The Senkaku/Diaoyu Islands remain the epicenter, with China’s military patrols and Japan’s coast guard responses escalating since early 2025. The islands’ estimated 100 billion cubic meters of natural gas reserves fuel this competition, as reported by Nikkei Asia on June 10, 2025.
2. Geopolitical Power Play: China views Japan as a linchpin in the U.S.-led containment strategy, including the Quad alliance. Recent joint U.S.-Japan military drills in the South China Sea, noted on X, have prompted Beijing to test Tokyo’s defensive capabilities and the U.S. security commitment.
3. Historical Grievances: China exploits the memory of Japan’s WWII occupation to stoke nationalism. State media campaigns in June 2025 have revived narratives of Japanese aggression, aligning with Xi Jinping’s efforts to unify public support amid economic slowdowns.
4. Economic Leverage: Despite $300 billion in annual bilateral trade, China uses economic tools like seafood bans and rare earth export restrictions to coerce Japan. The Diplomat reported on June 11, 2025, that these measures aim to force concessions on the Senkaku issue.
5. Technological Rivalry: Japan’s leadership in semiconductors and robotics clashes with China’s push for technological self-reliance. China’s theft of Japanese tech blueprints, as alleged in a June 2025 cybersecurity report, heightens this competition, with military applications adding urgency.
6. Environmental Concerns: Japan’s Fukushima wastewater release, approved by the IAEA in 2023, has been weaponized by China as an environmental grievance. Protests in Chinese cities on June 9, 2025, suggest Beijing is amplifying ecological narratives to justify its stance.

Japan’s Stance on the Escalation

Japan has responded with a blend of diplomacy and military preparedness. Prime Minister Shigeru Ishiba, in a June 12, 2025, press conference, condemned China’s carrier deployments as “unacceptable,” promising “decisive action” while avoiding escalation. Tokyo has bolstered its defense budget to 2% of GDP by 2027, acquiring U.S.-made Tomahawk missiles and enhancing missile defense systems. The U.S.-Japan “2+2” talks in July 2024 reaffirmed their alliance, with plans for a permanent U.S. Marine base in Okinawa. Public sentiment, with 92.2% viewing China unfavorably (Genron NPO, 2023), supports a strong stance, though pacifist groups urge dialogue, reflecting a societal divide.

Why China Wants Escalation

China’s escalation strategy serves multiple purposes:

• Deterring Alliances: By pressuring Japan, China tests the U.S. resolve and discourages the Quad’s expansion, as noted in a June 2025 RAND Corporation analysis.
• Domestic Nationalism: Amid a 4.5% GDP growth slowdown (World Bank, June 2025 estimate), Xi uses anti-Japan sentiment to rally support, with state media framing Japan as a regional threat.
• Military Testing: The PLA Navy’s carrier operations near Japan provide real-time data on combat readiness, aligning with Xi’s goal of a “world-class military” by 2049.
• Regional Dominance: Escalation weakens Japan’s confidence, potentially forcing territorial or economic concessions, enhancing China’s control over the East China Sea.
• Distraction from Internal Issues: Economic challenges, including youth unemployment at 17.1% (National Bureau of Statistics, June 2025), make external conflicts a convenient diversion.

Who Benefits from the Escalation?

Several actors gain from this tension:

• China: Short-term gains include bolstering nationalism and military experience, though long-term risks involve sanctions and isolation.
• United States: The U.S. justifies increased troop deployments and arms sales, with Lockheed Martin reporting a 15% profit surge in June 2025 due to Japan contracts.
• Defense Industries: Japan’s Mitsubishi Heavy Industries and U.S. firms benefit from heightened demand for missiles and submarines, boosting jobs and revenue.
• Russia: As China’s partner, Russia diverts global attention from Ukraine, with joint Sino-Russian naval drills near Japan reported on June 11, 2025.
• South Korea and Taiwan: These nations may strengthen their defenses, aligning closer with the U.S., though they risk collateral damage from a broader conflict.
• Global Energy Markets: Rising tensions could spike oil prices, benefiting producers like Saudi Arabia, with Brent crude up 5% in June 2025 (Reuters).

China-Japan standoff

The China-Japan standoff is a complex interplay of territorial, geopolitical, economic, technological, and environmental factors. China’s motives center on dominance, nationalism, and distraction, while Japan counters with a fortified alliance and public resolve. The escalation benefits China, the U.S., and defense sectors in the short term but risks a regional arms race. Diplomatic efforts, potentially led by ASEAN or the UN, are critical to de-escalate, as the Asia-Pacific’s stability hangs in the balance.
