International backing == bhutan
Delusional Indians think that because Japan and U.S conducted the Naval exercise. it means that both are backing India's stand over Sikkim stand-off, although neither U.S nor Japan stated officially regarding this matter.
India moved troops because of the fear or as usual unwarranted concerns that china can capture India's neck (siliguri corridor).
although siliguri corridor is miles far away from the actual construction of a road. that cant be captured until there wouldn't be full conventional war. because Siliguri Corridor is being protected by difficult terrains, rivers that make sure the safety of both side naturally.
India is saying it is our move to save our sovereignty and that's why Indian chest thumping is going on all over India that India stopped a road construction and saved her sovereignty.
To stop construction of a road and call it saving your sovereignty is totally insanity.
2nd India's biggest misunderstanding about the border defense
cooperation agreement 2005 between china & India.
According to Agreement.
"China and India have previously agreed that the disputes must be solved diplomatically. During the visit of the then Chinese premier Wen Jiaboa to India in 2005, Beijing and New Delhi signed a historic accord, agreeing to settle the decades-old border dispute without use of force.
and in 2013 when the then indian Prime Miniter manmohan Singh Visited China, the two states singed the Border Defense Cooperation Agreement, reaffirming that both shall "exercise maximum self-restraint,""not use force or face-offs occur along the disputed areas."
if you consider this agreement among China-India-Bhutan.. then India Violated the Agreement by using Force against Chinese Construction employees rather then Diplomatic Cooperation, although not a single bullet was fired but by using force, India violated the Agreement with China.
India moved troops on behalf of India's unwarranted Concerns. India didn't have any intention to confront with China just because of Bhutan, it is India's own unwarranted Concerns over Silliguri Corridor.
What Indian Army is doing in that area which dont belong to India at Doklam ? not even Indian claimed Area.
