The Sino-Indian border is generally divided into three sectors namely:
- The Western sector,
- The Middle sector, and
- The Eastern sector.
- The western sector: it is around 2152 km long. It is between Jammu and Kashmir and Xinjian province of China.
- Aksai chin: The Johnson’s line shows Aksai chin under India control while McDonald’s line shows it under China’s control.
- The middle sector: it is 625km long. It runs along the watershed from Ladakh to Nepal.
- The eastern sector: it is around 1140 km long. It was demarked by Henry Mc Mohan in 1913-14 under Shimla accord. China consider Mc Mohan line as illegal and unacceptable because during Shimla accord, Tibet was not a part of China.
