How the exam will ask it

Prelims

  • A tunnel boring machine excavates tunnels with a circular cross-section through soil or rock, and is widely used in metro, rail and hydropower works.
  • Export curbs by a major supplier country can raise costs and delay infrastructure projects in importing countries.
  • Reducing import dependence in capital goods is linked to the Make in India and Atmanirbhar Bharat approach.

Mains

GS-III (Infrastructure; industry): China's curbs on tunnel boring machines expose India's reliance on imported heavy construction equipment for metro, rail and hydropower tunnels. Policy responses include promoting domestic manufacturing, diversifying suppliers and building stockpile and servicing capacity. The way forward is to combine indigenisation with trusted partnerships so project timelines and costs are protected.
