In a visionary 2014 interview, Chinese rail engineer Wang Mengshu laid out plans for a high-speed railway connecting China to the United States via Russia and Canada, crossing the Bering Strait through a 200-kilometer tunnel. This ambitious, 13,000-kilometer (8,000-mile) line, designed to allow travel at 350 km/h, could enable passengers to reach the U.S. from China in less than two days, offering scenic views across multiple countries. The project, part of China’s “going global” rail strategy, would involve funding and technology exchanges among participants. The Trump-Putin summit this week puts this transcontinental vision in a better position to become a reality.
