Nathu La is a mountain pass in the Dongkya Range of the Himalayas between China's Yadong County in Tibet, and the Indian states of Sikkim and West Bengal in Bengal, South Asia. The pass, at 4,310 m (14,140 ft), connects the towns of Kalimpong and Gangtok to the villages and towns of the lower Chumbi Valley. The next few decades saw an improvement in ties leading to the re-opening of Nathu La in 2006. The opening of the pass provides an alternative route to the pilgrimage of Mount Kailash and Lake Manasarovar, and was expected to bolster the economy of the region by playing a key role in the growing Sino-Indian trade. However, while trade has had a net positive impact, it under-performed, and is limited to specific types of goods and to specific days of the week. Weather conditions including heavy snowfall restricts border trade to around 7 to 8 months. Roads to the pass have been improved on both sides. Rail routes have been brought closer. It is part of the domestic tourist circuit in south-east Sikkim. Soldiers from both sides posted at Nathu La are among the closest along the entire Sino-India border. It is also one of the five Border Personnel Meeting points between the two armies of both countries. 2020 border tensions and the coronavirus pandemic has affected tourism and movement across the pass.
