India has forcefully rejected Beijing’s latest claim over Arunachal Pradesh, calling the northeastern state an “integral and inalienable part of India,” after a UK based Indian citizen from the region was detained for hours at Shanghai Pudong International Airport.
The diplomatic flare-up began when Prema Wangjom Thongdok, an Arunachal-born Indian passport holder residing in the United Kingdom for more than a decade, reported that Chinese immigration officials detained her for 18 hours during a layover on November 21. Thongdok said authorities invalidated her passport on the grounds that her birthplace, Arunachal Pradesh, was “Chinese territory,” and mocked her by insisting she was “not Indian.”
Her account, posted on the social platform X on November 23, triggered swift intervention from Indian consular officials in Shanghai and Beijing, ultimately allowing her to leave the country. New Delhi later issued a formal demarche to Beijing, accusing China of arbitrary detention in violation of international air-travel conventions and China’s own 24-hour visa-free transit rules.
Beijing, however, dismissed the accusations. Chinese foreign ministry spokesperson Mao Ning reiterated China’s longstanding position that Arunachal Pradesh, referred to by Beijing as Zangnan, is part of “South Tibet,” and claimed there had been “no so-called detaining or harassing” of the traveler. China “has never recognised the so called ‘Arunachal Pradesh’ illegally set up by India,” Mao said.
India firmly pushed back. Foreign ministry spokesperson Randhir Jaiswal said China’s assertions “do not change the indisputable reality” of India’s sovereignty over Arunachal Pradesh. He added that Chinese authorities “have still not been able to explain their actions,” which New Delhi believes breach multiple international norms governing passenger transit.
The confrontation comes at a delicate moment as the two nuclear-armed neighbors attempt to stabilize relations following a bruising period of tension. After four years marked by mistrust and military standoffs, Prime Minister Narendra Modi visited China in August for the first time in seven years, where he and President Xi Jinping pledged to treat each other as partners rather than rivals.
But longstanding disputes simmer beneath the diplomatic language. India and China share a 3,800-kilometer border that remains poorly demarcated an ambiguity that has fueled territorial disagreements since the 1950s. Frictions reached a deadly peak in 2020 when soldiers from both sides clashed in the Himalayas, resulting in the deaths of 20 Indian and four Chinese troops.
The latest episode centered on a single traveler’s airport ordeal has reopened those geopolitical wounds, reminding both countries how quickly old tensions can resurface, even amid efforts to rebuild trust.
