The neighboring country, which is at loggerhead with India over its boundary, inaugurated the 435.5-km Lhasa-Nyingchi section of the Sichuan-Tibet Railway, ahead of the centenary celebrations of the ruling Communist Party of China (CPC) on July 1.

In November last year, Chinese President Xi Jinping had directed officials to expedite construction of the Sichuan–Nyingchi railway project in Tibet.

He had said that the new rail line would play a key role in safeguarding the border stability.

The Sichuan-Tibet Railway starts from Chengdu, capital of Sichuan Province, and travels through Ya”an and enters Tibet via Qamdo, shortening the journey from Chengdu to Lhasa from 48 hours to 13 hours.

Nyingchi is prefecture-level city of Medog which is adjacent to the Arunachal Pradesh border.

China claims Arunachal Pradesh as part of South Tibet, which is firmly rejected by India.

The India-China border dispute covers the 3,488-km-long Line of Actual Control (LAC).
