NEW DELHI — A suspected Chinese military aircraft breached Indian airspace over Sikkim on November 12, circling the border state for nearly 20 minutes despite repeated warnings from the Indian Air Force.
Congress leaders seized on the episode to launch a blistering assault against the Union government, demanding an immediate diplomatic protest from Prime Minister Narendra Modi. The aircraft allegedly defied established military communication channels before turning back across the frontier.
The breach was brazen.
"Lodge a strong protest with China," the party urged the Prime Minister, cautioning that the Centre must not issue Beijing another "clean chit." The sharp rebuke lands amid mounting political friction over military preparedness and persistent Chinese territorial pushback across the Eastern Sector.
The Sikkim airspace controversy erupted on the heels of a fiery public exchange between Congress general secretary in-charge communications Jairam Ramesh and Arunachal Pradesh Chief Minister Pema Khandu over cross-border transgressions.
Speaking on operational conditions along the border, Khandu sought to downplay civilian anxieties, maintaining that the frontier remains calm and that Indian troops retain firm control on the ground. Yet, his explanation of boundary realities triggered immediate political blowback.
"The Chinese do not consider the McMahon Line, bordering Arunachal, so sometimes it happens," Khandu stated, pointing to the sprawling 1,200-kilometre border the state shares with Tibet-China. "Transgression has happened, no doubt. But it keeps happening; it is not a new thing. Because there is no line demarcation at the border, it is not defined."

Congress leadership pounced on the admission. Ramesh pointed out that Khandu had flatly dismissed accounts of Chinese incursions into Taksing earlier this summer, only to now concede that incursions are routine occurrences along unmapped ridges.
Political battle lines hardened instantly.
| Sector & Location | Incident Reported | Official / Political Position | Status Along Border |
|---|---|---|---|
| Sikkim Airspace | Chinese military aircraft circled ~20 minutes on Nov 12 | Ignored IAF warnings; Congress demands formal protest | Standoff over aerial protocols |
| Arunachal Frontier | Undefined ~1,200 km border along McMahon Line | CM Khandu concedes transgressions occur amid lack of demarcation | Armed forces guarding lines; "no tension" reported by state |
| Taksing Sector | Summer border incursion claims | Previously denied by state leadership; revived by opposition | Contested operational assessment |
"Instead of asserting India’s position, BJP leaders are rationalising Chinese actions," Ramesh countered, accusing the ruling dispensation of attempting to normalize recurring violations along the Line of Actual Control. He argued that treating Chinese incursions as standard patrol routines undermines India's diplomatic leverage and military posture.
Beijing still refuses to recognize the historical McMahon Line, keeping thousands of troops deployed across forward ridges. With Parliament set to convene for its upcoming session, the opposition is preparing to force a high-stakes debate on the Sikkim airspace breach and the operational readiness of forward air defence squadrons.
