India has lodged a formal and strongly worded diplomatic protest with China after an Arunachal Pradesh–born Indian woman, Prema Wangjom Thongdok, was allegedly detained, harassed, and denied basic facilities by Chinese immigration authorities at Shanghai Pudong Airport on November 21, 2025. The incident has reignited longstanding tensions surrounding China’s territorial claims over Arunachal Pradesh and raised concerns about the treatment of Indian citizens in Chinese transit zones.
A Routine Transit Turns Into an 18-Hour Ordeal
Thongdok, an Indian national currently residing in the United Kingdom, was travelling from London to Japan with a scheduled three-hour layover in Shanghai. Upon arrival, Chinese immigration officials reportedly declared her Indian passport “invalid” solely because it listed her birthplace as Arunachal Pradesh. Authorities allegedly insisted that Arunachal Pradesh is “part of China,” refusing to acknowledge the legitimacy of her Indian documentation.
Her passport was confiscated, and she was held in the transit area for nearly 18 hours. During this period, she was allegedly denied food, water, and access to basic facilities. She also reported instances of verbal harassment and mockery by immigration personnel and airline staff. At one point, officials allegedly suggested that she apply for a Chinese passport, further aggravating the already fraught situation.
Thongdok also claimed she was pressured to purchase a new ticket through China Eastern Airlines and that the return of her passport was made conditional upon making this purchase. The prolonged detention caused her to miss her connecting flight and incur heavy financial losses related to travel and accommodation.
India Responds with a Strong Diplomatic Protest
New Delhi reacted swiftly and decisively. A strong demarche was issued to Beijing the same day, expressing deep concern over the “ludicrous” grounds for her detention. India reiterated that Arunachal Pradesh is an integral and inalienable part of India and condemned any attempt by China to challenge this sovereignty through administrative or immigration actions.
India’s Consulate in Shanghai intervened promptly, providing consular support and ensuring the eventual release of Thongdok. Government sources expressed concern that China’s actions may violate international civil aviation norms, including provisions under the Chicago and Montreal Conventions, which protect passengers in international transit zones.
Sovereignty Flashpoint in an Already Sensitive Region
The incident highlights the persistent geopolitical friction between the two nations. China continues to claim Arunachal Pradesh as “South Tibet,” despite India’s firm and long-established assertion that the state is an integral part of its sovereign territory. Similar disputes have surfaced previously in the form of stapled visas issued to Arunachal residents and China’s repeated cartographic assertions.
Thongdok, in her written complaint to Indian authorities, described her experience as “an insult to India’s sovereignty” and urged the government to seek accountability and compensation while ensuring that no other Indian citizen faces such treatment in the future.
Broader Implications and the Road Ahead
The incident may have broader diplomatic consequences as India weighs further steps to safeguard its citizens, especially those from border states. Key areas to watch include:
- Stronger diplomatic communication demanding assurances from China regarding the safety of Indian travellers.
- Greater scrutiny of airline and immigration practices involving Indian passport holders.
- Renewed domestic debate on travel advisories and awareness for citizens from Arunachal Pradesh.
As New Delhi awaits China’s formal response, the situation adds another layer of complexity to an already delicate bilateral relationship, underscoring how individual experiences can escalate into significant diplomatic flashpoints.
