A high-altitude tunnel is latest flashpoint in India-China border tensions

"A tunnel constructed high in the mountains of northeastern India has become the latest flashpoint in a simmering border dispute between New Delhi and Beijing.

The Sela Tunnel, inaugurated by Indian Prime Minister Narendra Modi earlier this month, has been hailed in India as a feat of engineering – blasted through the Himalayas at an elevation of some 13,000 feet (3,900 meters) – and a boon for the military, enabling faster, “all-weather” access to a tense de facto border with China. That’s caught the attention of Beijing, whose long-running dispute with New Delhi over their contested 2,100-mile border has seen the two powers clash in recent years." MS
