In 2023, the United States reiterated its position that Arunachal Pradesh is an integral part of India, a stance that aligns with its broader strategic support for India's sovereignty and territorial integrity. The reaffirmation comes against the backdrop of ongoing territorial disputes between India and China. China claims parts of Arunachal Pradesh as "South Tibet," but the region has been administered by India since its independence.
The USA's position is significant as it strengthens diplomatic relations between India and the US, particularly in the Indo-Pacific region where both countries share strategic interests. This support is also reflective of the growing defense and security partnership between India and the US, as well as their cooperation in countering China's assertiveness in the region. The US has consistently recognized India’s claims over Arunachal Pradesh and has called for peaceful resolution of border issues through dialogue and diplomacy.
