This independent analysis details the recent diplomatic crisis sparked by an incident at Shanghai Airport, providing a full background on the India-China border dispute over Arunachal Pradesh and assessing the potential for future escalation.
The Shanghai Flashpoint
Tensions between New Delhi and Beijing were recently reignited by the alleged detention and harassment of an Indian citizen from Arunachal Pradesh while transiting through China.
The Incident: UK-based Indian national Prema Wangjom Thongdok, traveling from London to Japan on a valid Indian passport, reported being held for approximately 18 hours at Shanghai Pudong International Airport (Al Jazeera). Chinese immigration officials allegedly declared her Indian passport “invalid” because her place of birth, Arunachal Pradesh, is claimed by China. She was reportedly pressured to purchase a new flight ticket until Indian consular officials intervened.
Official Reactions:
- India’s Stance: The Ministry of External Affairs (MEA) lodged a strong diplomatic protest (demarche) with Beijing, affirming that Arunachal Pradesh is an integral and inalienable part of India, a “self-evident fact” (Hindustan Times). India stressed that China’s actions violated international air travel conventions.
- China’s Stance: Chinese Foreign Ministry spokesperson Mao Ning denied allegations of detention or harassment, stating border checks were conducted “in accordance with laws and regulations.” Mao Ning reiterated Beijing’s long-standing position: “Zangnan is China’s territory. The Chinese side has never recognised the so-called ‘Arunachal Pradesh’ illegally set up by India.” (TRT World).
Full Fair Background: The Undefined Border
The latest incident is a direct manifestation of the long-standing and complex border dispute, which is split into two major sectors: Aksai Chin in the west and Arunachal Pradesh in the east.
The Historical Basis of the Conflict
The dispute over Arunachal Pradesh traces back to the British colonial era:
- India’s Claim (McMahon Line): India adheres to the McMahon Line, which was negotiated between British India and Tibet during the 1914 Simla Convention. This line, generally following the Himalayan watershed, defines the border in the Eastern Sector.
- China’s Claim (Zangnan): China rejects the McMahon Line, arguing that Tibet was not a sovereign entity and had no authority to sign the agreement. Beijing refers to the state as Zangnan (Southern Tibet) and lays claim to approximately 90,000 sq km of the territory. The unresolved boundary led to the 1962 Sino-Indian War, where Chinese troops briefly captured parts of the state before declaring a unilateral ceasefire and withdrawing, yet the boundary issues remained unresolved, setting a foundation of persistent strategic mistrust (Al Jazeera).
Chinese Assertion Tactics
Beyond military deployment, China uses administrative and diplomatic tools to reinforce its territorial claim:
- Stapled Visas: China has a policy of issuing stapled visas (not stamped directly into the passport) to residents of Arunachal Pradesh and India-administered Kashmir. This practice implicitly avoids recognising the citizens as Indian nationals. India has repeatedly protested this, leading to Indian athletic teams pulling out of competitions in China (Al Jazeera).
- Renaming and Infrastructure: Beijing has, in recent years, unilaterally renamed places (such as mountains, rivers, and residential settlements) in Arunachal Pradesh to Chinese names and built civilian villages inside disputed territory near the Line of Actual Control (LAC) (Drishti IAS).
- Protests of Visits: China consistently objects to visits by the Indian Prime Minister, President, or other senior leaders to Arunachal Pradesh, arguing that such visits complicate the boundary question (VOA).
Westferry Times Opinion: Diplomacy on Thin Ice
The latest passport denial incident is not a major military crisis, but a calculated act of diplomatic posturing by Beijing. By targeting a private citizen’s Indian passport at an international transit hub, China is sending a clear, cost-free message: it does not recognise the territorial integrity of India in the region.
While both Prime Minister Narendra Modi and President Xi Jinping have engaged in recent diplomatic “thaws”—often driven by a shared need to navigate global economic pressures (referencing independent economic analysis of global trade flows on GOV.UK)—the underlying reality of military and nationalistic rivalry remains. The core issue is the LAC, which is neither fully demarcated nor mutually agreed upon. Incidents like the Shanghai detention serve to keep the dispute highly visible and highly emotional for the Indian populace.
The inability of the world’s two most populous nations to resolve their boundary dispute, despite numerous talks and confidence-building measures, creates persistent instability that threatens regional peace. The diplomatic language is firm on both sides, making the necessary compromise appear “far-fetched” (IAI Istituto Affari Internazionali).
Potential Issues and the Risk of Fight
The possibility of a future conflict, while undesirable for both sides, remains real due to the militarisation along the border:
- Massive Military Build-up: Since the deadly 2020 Galwan Valley clash in the Western Sector, both sides have significantly fortified their positions and deployed more than 100,000 troops and advanced infrastructure along the LAC (Crisis Group).
- Eastern Flare-ups: While Galwan was in Ladakh, the Eastern Sector is equally volatile, evidenced by the 2022 scuffle in Tawang. Both nations are racing to complete strategic infrastructure (roads, tunnels, dams) to facilitate the rapid movement of soldiers and equipment, which inherently raises the risk of accidental escalation or deliberate skirmishes.
- Strategic Distrust: India views China as its primary security threat, replacing its traditional focus on Pakistan. As an analyst noted, while the recent spat is a “minor blip,” the overall strategy of viewing each other as rivals continues, meaning competition will persist (Al Jazeera).
The diplomatic freeze since 2020, despite some high-level meetings, means there is no robust mechanism to manage the high level of military deployment, leaving the door open for future, potentially violent, encounters.
