Around a year after the May 2020 standoff in eastern Ladakh, a new hotline between the two countries was established. The New Indian Express earlier reported that the new hotline was established between Indian Army in Kongra La, North Sikkim, and PLA at Khamba Dzong in the Tibetan Autonomous Region to further the spirit of trust and cordial relations along the borders.

The armed forces of the two countries have well-established mechanisms for communication at ground commander level. There are now six hotlines, with two in eastern Ladakh, two in Sikkim and two in Arunachal Pradesh.

The other five hotlines have been established along the meeting points at the LAC at Daulat Beg Oldi and Chushul in eastern Ladakh, Nathu La in Sikkim, and at Bum La and Kibithu in Arunachal Pradesh.

India shares a 3488-km border with China that runs along the states of Jammu & Kashmir, Himachal Pradesh, Uttarakhand, Sikkim and Arunachal Pradesh. The length of the border along Sikkim is 220 km. Sikkim also shares borders with Nepal and Bhutan

To the south of Sikkim lies the Siliguri Corridor, a narrow stretch adjoining Nepal, Bhutan, and Bangladesh, measuring about 170x60km, and at its narrowest, around 20-22km, which holds tremendous geopolitical importance. Functioning as a crucial link connecting the northeast of India with the rest of the country, it accommodates major national highways, railway lines, pipelines, and optical fiber connectivity.

In 2023, it was announced that border guarding forces are set to play a pivotal role in fortifying the security of the Siliguri Corridor, also known as the Chicken’s Neck, during peacetime.
