India’s diplomatic channels went into immediate and urgent action after a woman from Arunachal Pradesh was detained for nearly eighteen hours at Shanghai airport by Chinese immigration officials, who allegedly mocked her nationality and declared her Indian passport invalid on the grounds that Arunachal Pradesh is “Chinese territory.” The incident, which occurred on November 21, triggered a strong demarche from India to China in both Beijing and New Delhi, reigniting longstanding geopolitical tensions over Arunachal Pradesh and raising serious concerns about China’s conduct toward Indian citizens transiting through its airports.
Detention in Shanghai and the Humiliation Faced by the Passenger
The controversy began when Prema Wangjom Thongdok, an Indian citizen originally from Arunachal Pradesh and currently residing in the United Kingdom, arrived at Shanghai Pudong Airport for a three-hour layover en route to Japan for a vacation. She was carrying a valid Indian passport and a Japanese visa, and had booked a connecting flight with China Eastern Airlines. However, her routine transit turned into an ordeal when Chinese immigration officials stopped her and declared her passport invalid because of her birthplace.
According to Thongdok, immigration personnel insisted that her passport could not be recognized as legitimate since it listed Arunachal Pradesh as her birth state. China has repeatedly claimed Arunachal Pradesh as part of its territory, referring to it as “South Tibet,” a claim India has strongly and consistently rejected. Despite this established diplomatic position, the officials reportedly used the claim to justify stopping her from boarding the onward flight.
In her account shared on X, she described being detained for more than eighteen hours, questioned repeatedly and mocked by officials who made remarks such as, “Arunachal is not part of India,” and “You should apply for a Chinese passport, you’re Chinese, you’re not Indian.” The tone of the interrogation, she said, was humiliating, sarcastic and deeply offensive, particularly because she had transited through Shanghai a year earlier without any issues.
Thongdok also said she was denied basic amenities for long periods and felt helpless until she was able to contact Indian diplomatic authorities. She eventually reached out to the Indian embassies in both Beijing and Shanghai, who intervened promptly. Indian officials arrived at the airport, ensured she received food and assistance, and negotiated her release with Chinese authorities. Only after the Indian mission’s intervention was she allowed to leave the country.
She described the episode as one of the most distressing travel experiences she had ever encountered, particularly because of the mockery and the refusal to acknowledge her valid travel documents. Her narration of the incident has since gone viral, sparking widespread outrage across India and prompting questions about China’s treatment of Indian nationals, especially those hailing from Arunachal Pradesh.
India’s Strong Diplomatic Response and Wider Implications of the Incident
The Government of India reacted sharply once the details were confirmed. The Ministry of External Affairs conveyed a strong demarche to the Chinese government, both in Beijing and in Delhi, on the same day the incident occurred. Indian diplomats expressed unequivocal objection to China’s conduct, calling the grounds for her detention “ludicrous,” “unacceptable” and “in violation of international norms.”
According to people familiar with the matter, India emphasized that Arunachal Pradesh is an integral and inalienable part of India, and that its residents are fully entitled to carry Indian passports and travel freely. Any claim to the contrary, India stated, reflects neither international law nor bilateral agreements. Indian officials also highlighted that detaining a legitimate passport-holder merely on the basis of Chinese territorial assertions is both irrational and provocative.
India further underscored that the actions of the Chinese immigration authorities contravened international aviation conventions, including the Chicago Convention and the Montreal Convention, both of which govern global protocols for civil aviation, passenger rights and the treatment of international travelers in transit. Violations of these conventions, India noted, undermine the integrity of international travel systems and set a dangerous precedent.
At a time when New Delhi and Beijing have been attempting to stabilize their strained relationship, particularly after the Ladakh standoff and continuing military friction along the Line of Actual Control, India conveyed that such actions by Chinese officials introduce unnecessary obstacles. They also erode trust and complicate efforts to normalize bilateral ties. The message highlighted that harassment of Indian citizens, especially those from Arunachal Pradesh, only deepens the gulf between the two nations.
The incident must also be viewed in the broader context of China’s ongoing efforts to assert its territorial claims over Arunachal Pradesh. In recent years, Beijing has renamed dozens of towns, villages and geographical features in the state, issued “stapled visas” to residents of Arunachal Pradesh instead of standard visas, and protested visits by Indian officials to the region. The Chinese government’s narrative asserts that Arunachal is historically linked to Tibet, while India maintains that the state has always been part of its sovereign territory.
The detention of an Indian passport-holder because of their birthplace reflects an aggressive, real-world extension of China’s political claims, applied now even at international transit points. It signals a worrying escalation, where China’s territorial assertions are no longer confined to diplomatic statements or cartographic claims but are influencing the treatment of foreign nationals. Indian analysts have expressed concern that this development could affect not only travelers from Arunachal Pradesh but potentially from other regions disputed by China.
Meanwhile, Thongdok’s experience also highlights the vulnerability of Indian citizens traveling through China, especially in the current geopolitical climate. Her account of being mocked, ridiculed and denied access to her onward flight until Indian officials intervened touches on the broader debate around how Chinese authorities use administrative processes to reinforce political positions. What should have been a routine transit became a diplomatic flashpoint.
Back in India, the incident has triggered extensive discussions about whether Indian travelers, particularly those from Arunachal Pradesh, should avoid transiting through Chinese airports. Lawmakers and policy thinkers have argued that India may need to issue fresh advisories. Many have emphasized that if China continues such practices, India must consider reciprocal measures.
In the United Kingdom, where Thongdok lives, the Indian community also expressed concern about the targeting of Indian citizens by Chinese authorities, especially those from border states. The diaspora has called for stronger protections and increased diplomatic vigilance in cases where Indian nationals face harassment in foreign jurisdictions.
For China, the incident raises questions about its international image and adherence to global travel norms. By undermining the validity of an Indian passport—one recognized worldwide—it risks projecting itself as a state willing to override established international frameworks for the sake of political claims. This perception could have wider implications for global travelers, aviation companies and diplomatic missions.
Within China itself, the episode may reflect internal administrative instructions influenced by political narratives. Observers have noted that China’s immigration and public security bureaus often operate in alignment with broader territorial and ideological objectives set by the government. If such behavior becomes normalized, similar incidents may occur in the future, exacerbating tensions.
For India, the episode is another reminder of the delicate and often volatile nature of its relationship with China. The incident underscores the need for strong diplomatic vigilance, clear communication and assertive responses when Indian citizens’ rights and dignity are compromised abroad.
In the immediate aftermath, India ensured that Thongdok was safely allowed to continue her journey, but the broader issues raised by her ordeal—territorial claims, international law, civil aviation norms, and border politics—remain far from resolved. The event has also deepened public sentiment in India about China’s aggressive posturing, making it not just a diplomatic issue but a matter of national concern.
