India–Nepal Border Dispute:

Nepal Prime Minister Balen Shah triggered a massive domestic political storm, by claiming that Nepal has also encroached on Indian territory, challenging Kathmandu’s traditional narrative.
- The India-Nepal border dispute is a long-standing territorial disagreement centered primarily around three strategic zones along their 1,850 km shared open border.
- The core structural friction involves the Kalapani-Limpiyadhura-Lipulekh tri-junction in the western sector and Susta in the eastern riverine sector.
- The open international boundary stretches across five Indian states, making its precise demarcation a vital matter of subcontinental security:
- Uttarakhand (shares the highly contested Western/Kalapani sector)
- Uttar Pradesh
- Bihar (shares the riverine Susta sector)
- West Bengal
- Sikkim
