In India, how many States/Union Territories have more than two international boundaries?

In India, four States/Union Territories share international boundaries with more than two countries. These are West Bengal, Sikkim, Arunachal Pradesh, and the Union Territory of Ladakh. West Bengal shares borders with Bangladesh, Nepal, and Bhutan. Sikkim is bordered by China, Nepal, and Bhutan. Arunachal Pradesh shares its international frontiers with China, Bhutan, and Myanmar. Following the reorganization of Jammu and Kashmir, the Union Territory of Ladakh now shares borders with three countries: Pakistan, China, and Afghanistan. While some sources previously grouped Jammu and Kashmir as a single entity with multiple borders, current administrative divisions confirm that Ladakh is the specific unit bordering three nations [1]. Other states like Uttarakhand or Mizoram only share borders with two countries. Thus, there are exactly four such administrative units in India.
