With which country, Manipur shares its border?

Concept: An Indian state's international border is the boundary it shares with a neighbouring foreign country, which is different from the inter-state boundaries it shares with other Indian states. To answer such a question, identify which side of the state touches a foreign nation.

Application to Manipur: Manipur lies in India's North-East. Its eastern and south-eastern sides form an international boundary with Myanmar (formerly Burma). Its other sides are inter-state boundaries with the Indian states of Nagaland, Assam and Mizoram. So the only foreign country Manipur borders is Myanmar.

Manipur's boundaries:

• North: Nagaland (Indian state)

• West: Assam (Indian state)

• South / South-west: Mizoram (Indian state)

• East / South-east: Myanmar (foreign country - international border)

Cross-check: Among the other choices, China borders Himalayan regions such as Ladakh, Arunachal Pradesh and Sikkim; Nepal borders Uttarakhand, Uttar Pradesh, Bihar, West Bengal and Sikkim; Bangladesh borders West Bengal, Assam, Meghalaya, Tripura and Mizoram. None of these touch Manipur, confirming Myanmar as the answer.
