Why in news?

China has introduced fresh global export restrictions on tunnel boring machines (TBMs) — critical equipment for metro rail and highway construction — adding to earlier curbs on rare earth magnets that have already hurt Indian automobile manufacturers.

These 3,000-tonne machines are vital for several Indian infrastructure projects, most notably the 508-km Mumbai-Ahmedabad High-Speed Rail (bullet train) Corridor, which includes a 7-km undersea tunnel. The restrictions, announced by China’s Commerce and Industry Ministry, will take effect from November 18, 2026.

Why TBMs Matter

• TBMs ensure safer excavation compared to conventional blasting methods — crucial for India’s bullet train project, where the tunnel passes through densely populated areas.
• Widely used across Europe, Canada, the US, and Australia, TBMs are essential for modern underground transit infrastructure.
• China’s new rule requires export operators to apply for a licence under provisions of its export control law governing dual-use items.

India’s Ongoing TBM Troubles

• India has faced TBM import delays since 2024, though shipments resumed in March 2026 as bilateral tensions eased somewhat.
• In a widely-noted 2024 incident, India raised the issue with Germany’s then Vice-Chancellor during a Delhi Metro ride.
• It flagged that machines made in China by German TBM leader Herrenknecht for delivery to India were being blocked.

Impact Depends on How China Uses Its Leverage

• The new licensing mechanism gives China greater bargaining power in trade negotiations — but the actual impact on India depends on how selectively it is applied.
• Union Commerce Minister noted that India is working to develop the relationship with China once again, though “the last word has not yet been scripted.
• Meanwhile, EAM S. Jaishankar and FM Nirmala Sitharaman have flagged concerns over the “one-sided” and “tilted” India-China trade balance.

The Trade Deficit Backdrop

• India’s trade deficit with China in the first half of 2026-27 stood at $69 billion — 27% higher than the same period last year.
• India has simultaneously:
  • Opened doors to Chinese investment in select strategic sectors like power.
  • Ramped up anti-dumping measures against Chinese goods.
• As per a report, India opened 18 anti-dumping and anti-subsidy investigations in the July–September quarter — more than any other country, with China as the single largest target.

The Bigger Picture: China’s Global Trade Strategy

• China’s restrictions arrive amid high-stakes negotiations with both the US (currently in a two-month trade truce) and the EU (engaged in talks after EU curbs on Chinese EVs, EV batteries, and steel-protection measures).
• China’s global trade surplus hit $1.2 trillion in 2025, expected to exceed $1 trillion again in 2026.
• A Rhodium Group report (September 2026) found that China’s rising export share comes at others’ expense:
  • By 2030, the US is projected to lose 1.2 percentage points of global trade share.
  • Indonesia (-0.8pp), Canada (-0.5pp), Germany (-0.4pp), Netherlands (-0.4pp).
  • Rest of the world combined: -4.6pp — roughly matching China’s estimated +8pp gain.

Conclusion

China’s TBM export curbs, following earlier restrictions on rare earth magnets, reveal a recurring pattern — Beijing’s willingness to leverage its dominance over critical technologies and equipment as a tool in broader trade diplomacy.

For India, this exposes a strategic vulnerability: dependence on Chinese-manufactured or Chinese-routed machinery for flagship infrastructure projects like the bullet train corridor.

As India balances the dual imperatives of engaging economically with China while protecting its domestic industry and trade interests through anti-dumping action, episodes like this underscore the urgent need for diversifying supply chains and building indigenous capacity in critical construction technology.
