NEW DELHI, NOV 26 – New Delhi has asserted that Arunachal Pradesh is an “integral part” of India in response to Beijing’s claim over the territory as the two countries rowed over the detention of an Indian citizen at Shanghai Airport.

On Tuesday, India had issued a demarche to China over the detention of Prema Wangjom Thongdok, a UK-based woman from Arunachal Pradesh, at the Shanghai airport. Thongdok had said immigration officials had held for 18 hours and “mocked” her by saying the region was not a part of India.

China says Arunachal Pradesh, which Beijing calls Zangnan, is a part of South Tibet — a claim India has repeatedly dismissed. Beijing has renamed places in the northeastern Himalayan state multiple times, prompting strong reactions from New Delhi.

Responding to queries during a press briefing on Tuesday, China’s foreign ministry spokesperson Mao Ning had said that “Zangnan is China’s territory”.

“The Chinese side has never recognised the so-called ‘Arunachal Pradesh’ illegally set up by India,” she said. She further stated there was “no so-called ‘detaining’ or ‘harassing’” of the woman at the Shanghai Pudong International Airport, adding that authorities carried out checks in accordance with the law.
