Which of the following regions within Indian territory were claimed by China?

NEFA

The correct answer is Option (3) → NEFA

" Two developments strained this relationship. China annexed Tibet in 1950 and thus removed a historical buffer between the two countries. Initially, the government of India did not oppose this openly. But as more information came in about the suppression of Tibetan culture, the Indian government grew uneasy. The Tibetan spiritual leader, the Dalai Lama, sought and obtained political asylum in India in 1959. China alleged that the government of India was allowing anti-China activities to take place from within India. A little earlier, a boundary dispute had surfaced between India and China. India claimed that the boundary was a matter settled in colonial time, but China said that any colonial decision did not apply. The main dispute was about the western and the eastern end of the long border. China claimed two areas within the Indian territory: Aksai-chin area in the Ladakh region of Jammu and Kashmir and much of the state of Arunachal Pradesh in what was then called NEFA (North Eastern Frontier Agency). Between 1957 and 1959, the Chinese occupied the Aksai-chin area and built a strategic road there. Despite a very long correspondence and discussion among top leaders, these differences could not be resolved. Several small border skirmishes between the armies of the two countries took place."
