China is rewriting the rules of global trade with its most ambitious infrastructure project yet. From the record-breaking Jintang Tunnel — a 16.18 km undersea tunnel carrying high-speed trains at 250 km/h, with two massive tunnel boring machines converging beneath the ocean floor — to the jaw-dropping Bohai Strait Cross-Sea Channel, a planned 120 km undersea high-speed rail link designed to slash a multi-hour sea crossing to just 40 minutes, China is building infrastructure the world has never seen before.
