Asian relations with Northeast India

[1] The East Asian countries of Japan and Korea have significant contemporary influence over and cultural similarities with Northeast India; Northeast India engages to a significant extent with Korean and Japanese culture and has been receiving infrastructural investment from Japan.

[4] In the late 19th century, the British sent an expedition to guarantee suzerainty in Sikkim, aiming to secure it from Tibet.

[7] Historically, Northeast India and Japan have been connected to some extent through Buddhism; other cultural similarities have existed for millennia, such as in food and through an appreciation for nature.

Part of this alienation is due to local insurgents and others banning Hindi cinema and other potential tools of "Indianization" in the region.

[26] Immigration from Bangladesh has been a concern for indigenous populations in Northeast India, which oppose significant demographic change.

Both places were part of British India for several decades; the dynamics of British rule in the region, which was the first time that a pan-Indian empire had fully conquered the Northeastern South Asian space, and Myanmar's 1937 separation from Indian administration, still affect their border regions today.

[35][36] There are substantial cross-border ethnic ties, with the Indian government having allowed a limited amount of unregulated movement across the border from 2018 to 2024.

There are also analogues of Thailand’s Songkran festival in Northeast India (Sangken in Arunachal Pradesh and Bohag Bihu in Assam).
