Shanghai Passport Dispute Tests India China Thaw Over Arunachal Pradesh

An 18 hour airport ordeal reaches diplomatic channels

Pema Wangjom Thongdok, an Indian citizen who has lived in the United Kingdom for about 14 years, says she spent about 18 hours stranded at Shanghai Pudong Airport after Chinese border officers rejected her Indian passport because it listed Arunachal Pradesh as her birthplace. She was traveling from London to Japan on 21 November 2025.

India lodged a strong protest, calling the action arbitrary and a breach of international air travel norms. Its Ministry of External Affairs also said the treatment conflicted with China's own policy permitting airport transit without a visa for up to 24 hours for passengers of all nationalities.

China rejected the allegation that Thongdok was detained or harassed. Its Foreign Ministry said border inspection officers acted lawfully, took no compulsory measures and protected her rights. It also said the airline supplied meals and a place to rest.

The disagreement reaches beyond one missed connection. India administers Arunachal Pradesh and regards it as an integral and inalienable part of the country. China claims the state, calling it Zangnan or South Tibet. In Shanghai, according to Thongdok, that territorial dispute became an argument over her nationality and her right to continue traveling on an Indian passport.

By 26 November, the episode had become another test of efforts to improve relations between the two countries. Direct flights have resumed, senior leaders met in August, and officials have been working on patrol arrangements along the frontier. Those steps have reopened opportunities for contact, while the airport dispute has brought their unresolved differences back into public view.

What happened at the transit checkpoint

Thongdok said she had passed through Shanghai on previous journeys without a problem. This time, an immigration officer separated her from the queue after noticing the birthplace recorded in her passport.

In her account, shared on social media and with Indian media outlets, officers told her that the document was invalid because it named Arunachal Pradesh. She said she was prevented from boarding her onward flight to Japan despite having a valid visa, and remained in the transit area while officials withheld her passport.

Thongdok described officials mocking her identity and telling her to seek a different passport. Recounting their words, she said:

They said, "Arunachal is not part of India." They laughed and told me, "You should apply for a Chinese passport, you are Chinese, you are not Indian."

Indian consular staff in Shanghai contacted Chinese authorities and the airline. Thongdok was eventually allowed to continue her journey after about 18 hours. She described the experience as humiliating and said missed bookings caused financial losses.

Thongdok also said she missed her flight and was told to rebook to get her passport back. Her account puts the practical consequences alongside the dispute over nationality: a journey interrupted, a travel document withheld and arrangements that had to be changed while she waited for assistance.

China denies detention and harassment

Mao Ning, a spokesperson for China's Foreign Ministry, said border inspection authorities carried out their checks in accordance with laws and regulations. She maintained that the process was fair, that no compulsory measures were taken and that Thongdok's lawful rights were fully protected.

Mao denied detention or harassment and said the airline provided resting facilities and meals. China's position presents the episode as a lawful border inspection, while Thongdok describes being unable to board her flight or recover her passport during a prolonged wait.

Beijing also repeated its territorial claim to Arunachal Pradesh, using the name Zangnan. The disagreement therefore involves both what happened inside the airport and why the birthplace entry became an issue. China defended the conduct of its border authorities while restating the claim that India rejects.

India says the action undermines trust

India's Ministry of External Affairs said the matter was raised at a very high level. Its protest challenged the treatment of an Indian citizen, the rejection of her passport and the handling of a journey that involved transit through China.

Randhir Jaiswal, the ministry's spokesperson, linked the episode directly to efforts to repair relations. He said:

Arbitrary actions by China involving an Indian citizen from Arunachal Pradesh are most unhelpful toward efforts to build mutual trust and move toward normalization of bilateral relations.

Jaiswal also restated India's position on the state and the citizenship of its residents:

Arunachal Pradesh is an integral and inalienable part of India. No amount of denial by the Chinese side will change this indisputable reality.

The ministry said residents of Arunachal Pradesh carry valid Indian passports. Opposition leaders urged the government to speak firmly to Beijing, arguing that the nationality and dignity of Indian citizens must never be questioned abroad.

New Delhi's response connects the individual case to a wider diplomatic concern. As the governments try to rebuild confidence, India says actions affecting travelers from Arunachal Pradesh work against that effort.

Why Arunachal Pradesh is disputed

Arunachal Pradesh stretches across high mountains and valleys along the Line of Actual Control, the de facto boundary between India and China. A de facto boundary is the line used in practice, even when the countries have not agreed on a final border. India administers the state and holds elections there.

China claims the region and rejects the McMahon Line, which India treats as the frontier. The border question dates to the early twentieth century and the 1914 Shimla talks, where British and Tibetan representatives drew that line. Beijing never accepted it.

India and China fought a brief war in 1962. Their territorial disagreements also extend beyond Arunachal Pradesh. India claims Aksai Chin, a plateau to the northwest that China has controlled since the 1960s and that connects Xinjiang and Tibet.

Arunachal Pradesh has strategic and symbolic importance for both governments. It anchors India's northeast and has deep cultural links with Tibet. Tawang, home to a major monastery, is the birthplace of the sixth Dalai Lama. For Beijing, its claim to the region connects with policy on Tibet. For New Delhi, the dispute concerns sovereignty and the rights of more than a million Indian citizens.

Those competing positions help explain why a birthplace entry can become politically sensitive. India's administration of the state and China's claim to it shape how the two governments respond when the dispute reaches official documents.

From border clashes to disputed paperwork

The frontier has remained a source of confrontation despite talks intended to build confidence. In June 2020, soldiers from both countries clashed in the Galwan Valley in Ladakh. In late 2022, troops scuffled near Tawang in Arunachal Pradesh.

Travel documents have also become part of the dispute. China has issued stapled visas to some residents of Arunachal Pradesh, a practice India rejects. These are visas attached separately to a passport rather than placed on its pages.

New Delhi has also protested Chinese attempts to rename places within the state. India maintains that changing names does not change the facts on the ground. The Shanghai episode brings another form of paperwork, the birthplace field in a passport, into the same territorial disagreement.

The main events span more than a century:

• 1914: British and Tibetan representatives drew the McMahon Line during the Shimla talks. China does not recognize it.
• 1962: India and China fought a brief war.
• June 2020: Soldiers from both countries clashed in the Galwan Valley in Ladakh.
• Late 2022: Troops scuffled near Tawang in Arunachal Pradesh.
• August 2025: Prime Minister Narendra Modi visited China and met President Xi Jinping.
• 21 November 2025: Thongdok's transit through Shanghai became the subject of a dispute over her Indian passport.
• By 26 November 2025: India had lodged a strong protest, and China had denied detention or harassment.

What the 24 hour transit policy means

China permits many travelers to pass through its international airports without a visa for up to 24 hours, often while remaining in the airside area. Airside means the part of an airport beyond the usual passenger checks, where travelers wait for connecting flights.

Border inspection officers still decide whether passengers may use transit arrangements. They can restrict movement or refuse carriage in specific cases. India's complaint is that Thongdok's treatment breached international air travel standards and China's own transit policy. China says its authorities followed the law.

A passport's birthplace field is ordinarily a biographical record: it tells authorities where the holder was born. It does not create or surrender a territorial claim. Telling a traveler that an otherwise valid, machine readable passport is invalid because of that entry is unusual, especially during an international connection.

A machine readable passport contains information in a format that airport equipment can scan. In this case, the dispute described by Thongdok concerned the place written in the document, rather than the ordinary task of reading its information.

International transit standards aim to keep connecting journeys moving smoothly. India's objection focuses on the interruption of that process, while China's response rests on the authority of its border inspectors. The two positions leave the treatment of the traveler at the center of the diplomatic exchange.

A setback during efforts to improve relations

India and China have been trying to halt the deterioration in relations that followed the 2020 crisis. Direct flights have restarted, officials have revived exchanges involving people from the two countries, and discussions on patrol arrangements have sought to reduce friction along the frontier.

Modi's August visit to China, where he met Xi, was his first such visit in years. Both sides said they wanted partnership rather than rivalry. The Shanghai case has arrived during that careful thaw, making the handling of an ordinary traveler part of the test of whether goodwill can carry into everyday decisions.

Praveen Donthi of the International Crisis Group described the episode as a reminder of the persistence of the border dispute despite diplomatic outreach. He said:

This incident underlines how stubborn the border dispute is despite recent outreach. For Beijing, control over the region is tied to policy on Tibet. For India, it is a question of sovereignty.

The governments also have reasons to maintain engagement. Trade ties are deep, flights have resumed after a long gap, and both sides have invested political capital in stabilizing the frontier. Preventing similar incidents would support those efforts by reducing another source of friction.

Airlines and passengers face the practical costs

Airlines have limited room to act when immigration officers reject a travel document. Carriers must comply with decisions at border checkpoints, which can leave a passenger waiting in a transit zone while consular staff, airline managers and officials seek a resolution.

Thongdok's account illustrates the costs of that wait. She says the loss of her connection disrupted bookings and caused financial losses, while the disagreement over her passport left her dependent on intervention before she could continue.

Travelers can check transit eligibility with airlines and official immigration portals before booking. They can also consider routes that avoid sensitive transit points, keep consulate contact details accessible and allow extra time between flights. Border decisions remain in the hands of the authorities, so those preparations may help passengers obtain assistance when a problem arises.

The case is likely to continue through established diplomatic channels. India will press its position that residents of Arunachal Pradesh should face no special obstacles when traveling on Indian passports. China is expected to continue defending its inspection procedures and repeating its territorial claim, including its use of the name Zangnan.

No date for a further decision or diplomatic meeting on this case was given. As of 26 November, Thongdok had continued her journey, while the two governments remained divided over her treatment and the territorial claim behind the dispute.
