China dominates the global market for tunnel-boring machines, and India is among its main customers. The controls, due to take effect later in November 2026, also cover high-altitude concrete-spraying equipment and components. Beijing says countries and regions with disputes with China will face stricter rules. India is building roads and railways near its disputed Himalayan border; an analyst says the curbs could slow some projects there.
