India-China Trade Tensions Over Tunnel Boring Machines

Why in the News?

China's Ministry of Commerce announced that exporters of tunnel boring machines (TBMs) must obtain licences under its dual-use export control law from 18 November 2026. This has raised concerns in India about supply chain disruptions and bilateral trade tensions.

Key Highlights

• China's Global Times stated TBM exports for "legitimate civilian projects" would be approved.

• India's Commerce and Industry Minister warned of developing domestic TBMs to counter export restrictions.

• The Union Cabinet approved a ₹7,280-crore scheme in 2025 for rare earth magnet manufacturing.

• India is preparing a production-linked incentive scheme for polysilicon manufacturing.

• India initiated 18 trade-defence investigations in Q3 2026, mostly targeting China.

• TBMs are essential for projects like the Mumbai-Ahmedabad High-Speed Rail Corridor.

Know the Basics

• Tunnel boring machine (TBM): A machine used to excavate tunnels with a circular cross-section, often for infrastructure projects.

• Dual-use items: Goods that have both civilian and potential military applications, subject to export controls.

• Rare earth magnets: High-performance magnets made from rare earth elements, critical for electronics and renewable energy technologies.

• Production-linked incentive (PLI): A government scheme to boost domestic manufacturing by providing financial incentives.

Detailed Analysis

China's Export Control Law and Its Implications

• China's export control law mandates licences for TBMs and other dual-use items, effective 18 November 2026.

• The law raises concerns about the potential weaponisation of supply chains, as seen in past disruptions of rare earth magnet imports.

India's Response to TBM Export Restrictions

• India's Commerce Minister warned of developing domestic TBMs to reduce dependence on imports.

• India has faced TBM import delays since 2024, affecting infrastructure projects like the Mumbai-Ahmedabad High-Speed Rail Corridor.

India's Trade-Defence Actions Against China

• India initiated 18 anti-dumping and anti-subsidy investigations in Q3 2026, the highest globally during this period.

• China was the primary target of India's trade-defence measures, reflecting growing economic tensions.

Border Tensions and Bilateral Relations

• India-China border tensions persist, with face-offs reported in Arunachal Pradesh in October 2026.

• MEA emphasised that peace at the Line of Actual Control is critical for improving bilateral ties.

Significance for India

• TBMs are crucial for India's infrastructure, including the bullet-train project.

• Export restrictions highlight India's vulnerability to supply chain disruptions.

• India's trade-defence actions against China reflect a strategic response to economic pressures.

• UPSC could test this in International Relations or Economic Development, linking trade policy to geopolitics.

Challenges

• China's dual-use export controls could delay critical infrastructure projects in India.

• India's reliance on imports for rare earth magnets and TBMs exposes it to supply chain risks.

• Ongoing border tensions with China complicate efforts to improve bilateral trade relations.

Way Forward

• The Ministry of Commerce should accelerate domestic TBM development programmes.

• India must implement the PLI scheme for polysilicon manufacturing to strengthen the solar value chain.

• MEA should engage China diplomatically to ensure fair trade practices and resolve border issues.

• Industry stakeholders should diversify supply chains to reduce dependence on Chinese imports.
