For decades, the Siliguri Corridor was treated as a geographical vulnerability to be quietly managed. Today, it has emerged as a focal point of eastern geopolitics.
Sources said China has been slowly increasing its troop level in the Doklam Plateau.
'Does the Indian army's new assertiveness risk a clash escalating into shooting and possibly skirmishes?' asks Ajai Shukla.
'The Chinese forces in the narrow Chumbi Valley are currently in the line of sight and fire of Indian forces poised on the ridges along the Sikkim-Tibet border.' 'Aware of this vulnerability, the Chinese have been eyeing the Doklam plateau,' explains national security expert Nitin A Gokhale.
Suddenly the sands are shifting and even friends are acting strange.
Lt Gen Kalita also stated that the Army is constantly monitoring the activities across the border and is well prepared to meet any emerging challenges.
'When Modi was having his maiden meeting with Donald Trump, China is up to its old tricks again, by causing a distraction on the Doklam plateau,' says B S Raghavan, the distinguished civil servant.
China is spending billions of dollars to improve infrastructure in Tibet and other parts of its border with India. Claude Arpi explains why New Delhi can't afford to ignore Beijing's plans.

Air Chief Marshal said his force is ready for a full spectrum operation but added that any decision on surgical strike involving the IAF has to be taken by the government.
The Chinese authorities have been rapidly building defence infrastructure along the Line of Actual Control, indicating that they are preparing for a long period of tension with India, points out Jayadeva Ranade, the former senior RA&W officer and China expert.
China will use airpower to support Pakistan from the start of a war. China will use the opportunity to at least take Ladakh. Its growing navy will prevent India from blockading or attacking the Makran Coast. And thanks to Chinese weapons, Pakistan keeps expanding its forces, observes Ravi Rikhye.
A new book reproduces original Chinese maps that contradict Chinese propaganda. The book reveals Chinese intelligence admissions that Beijing never maintained any army base, customs office or other government function in the disputed area until 1983.
'India's military posture has become significantly stronger than China's on the 3,500-kilometre Line of Actual Control.' 'This is enhancing confrontation between the two sides,' points out Ajai Shukla.
'When sensitive territory goes into the hands of your enemy. he becomes more powerful in military terms.' 'Assuming the Chinese take over the Doklam Plateau they will not stop at that.' 'They will keep ingressing, and it will be easier for them to further expand their territory.' 'I feel the Chinese will vacate that area in two months after it begins to snow.'
The operational alert allows troops to get acclimatised to high altitudes, renovate the bunkers and trenches from which they would fight, break out ammunition, and carry out the coordination needed to fight an integrated defensive battle.
Until last month more than two-thirds of the Indian Army was deployed against Pakistan. Of 14 army corps, just four-and-a-half faced China, while more than twice that number was ranged against Pakistan.
In all the noise surrounding the Dok La confrontation, Claude Arpi focuses on a crucial issue that has hardly been covered -- the construction of roads for the armed forces and the local population to reach the most remote border posts.
India has experienced hands and will emerge with flying colours, declares Inspector General Gurdip Singh Uban (retd).
It also dismissed Jaitley's remarks that India of 2017 is different from what it was in 1962, saying China too is different.
'This is potentially escalatory, as China does not believe that India has any basis for interfering in a bilateral dispute between China and one of its neighbours.'
'The Himalayan people may not represent a large or politically influential section of the population, but India's security depends on them.' 'Let us hope Sikkim remains a beacon of stability,' says Claude Arpi after a recent visit to the picturesque north eastern state.
'How can a State, which claims to be a responsible power, unilaterally grab a "disputed" area to build a road on it?' asks Claude Arpi.
This quiet assertion of China has allowed various smaller countries of South Asia to play China off against India. Most states in the region now use the China card to balance against the predominance of India. Forced to exist between their two giant neighbours, the smaller states have responded with a careful balancing act, says Harsh V Pant.
'Chinese leaders rarely receive their foreign guests in cities other than Beijing. Such respect for India!' 'Does it mean that Modi could replicate "the warmth and unconventional way" by sending Indian troops into Tibet, as Xi did in Chumur (Ladakh) when he arrived in India? Of course, Indians are far too polite to do so,' says Claude Arpi.
