This study examines the functional transformation of transnational infrastructure from physical connectivity to a medium of civilizational exchange within the context of the Belt and Road Initiative. Taking the Karakoram Highway as the central case, it analyzes the historical construction process through which this infrastructure became a symbol of China-Pakistan friendship: between 1966 and 1979, over two thousand Chinese road workers completed this "Eighth Wonder of the World" at tremendous cost of life under extreme conditions, reshaping regional spatial patterns and establishing the material foundation for emotional integration and commercial exchange between the two countries. The study further connects the China-Pakistan Economic Corridor planning with the concept of "a community with a shared future for mankind," highlighting how the Karakoram Highway continues to serve as a core medium for promoting people-to-people connectivity. Focusing on documentary texts regarding the highway's construction history produced by both China and Pakistan, and employing intertextuality and spatial media theories, the research examines the "ideological clusters" differences in cinematic narratives across different social contexts, treating transnational discursive practices as a process of "mutual subjectivity" in meaning negotiation, with the aim of excavating the contemporary value of highway imagery in cross-cultural communication and providing discursive insights for infrastructure cooperation in the Global South.

I. The Creative Origins and Contemporary Context of Karakoram Highway Documentaries

This section reviews the creative background and historical context of Karakoram Highway documentaries in both China and Pakistan. The Pakistani documentary film *Where Man Meets Mountain* was jointly produced by the Inter-Services Public Relations and the Frontier Works Organization, narrating the road construction journey in Urdu with distinct characteristics of military mobilization and national security narratives, receiving high praise from government leadership after its premiere. The Chinese television documentary *Secretly Building the China-Pakistan Highway* emerged in the context of television documentary reform in the early 21st century, integrating political elite discourse with mass narrative, constructing the sublime national spirit of road-building collectives through an omniscient perspective. These two works, due to their highly congruent temporal-spatial references and the isomorphism and differentiation in textual texture, constitute core samples for comparative analysis: the former emphasizes military epic writing, while the latter focuses on collective eulogy and the image-shaping of great-power builders; both form divergent symbolic systems around sacrifice, natural space, and national friendship, providing irreplaceable analytical objects for exploring ethnic emotional mobilization in cross-cultural audiovisual texts, "other" media imagination, and the historical logic of people-to-people connectivity in the Belt and Road Initiative.

II. Spiritual Narrative and Discursive Construction in China-Pakistan Karakoram Highway Documentaries

Introducing intertextuality theory, this section treats the Chinese documentary *Secretly Building the China-Pakistan Highway* and the Pakistani documentary *Where Man Meets Mountain* as two text systems that are both independent and dialogic, analyzing their "isomorphic yet heterogeneous" spiritual narrative paths from five dimensions.

At the level of narrative subjects, both sides demonstrate structural differentiation. The Pakistani side, relying on military background, constructs "elite and military discourse," with interviewees being retired senior officers from the FWO, emphasizing military rank, position, and strategic vision; the Chinese side, due to historical confidentiality, shapes a "civilian epic," with interviewees mostly being ordinary road workers, medical staff, and family members of martyrs, with brief identity introductions requiring inference of division of labor through interview details, echoing the "secret" in the documentary title. This differentiation constitutes an intertextual mirror in cross-cultural contexts.

In the geopolitical dimension, both documentaries embed road construction history into the Cold War framework for cinematic confirmation. The Pakistani side emphasizes Chinese aid against the backdrop of American embargo, while the Chinese side presents historical nodes such as Premier Zhou Enlai's promise to assist in construction and the "Eight Principles" of foreign economic and technical assistance. Both sides repeatedly reinforce discourses such as "mutual assistance," "anti-hegemony," and "friendship," providing historical legitimacy endorsement for today's "China-Pakistan community with a shared future" and the Belt and Road Initiative.

Regarding spatial memory, both texts juxtapose the highway with the ancient Silk Road, completing a temporal dialogue spanning millennia. The Chinese side cites Professor Dani's archaeological works, presenting rock carvings and relics along the route; Pakistani scholars emphasize the cooperative traditions on the eastern side of Islamic civilization. The Karakoram Highway thus transcends its transportation attributes, becoming a spatial metaphor for the contemporary continuation of Silk Road spirit.

Concerning the sublime aesthetics of traumatic memory, both sides employ six strategies: citing foreign experts' doubts that the project was "impossible to complete" to highlight the miracle; interviewing witnesses to recall extreme experiences such as frostbite amputations and primitive labor; using voice-over and imagery to reproduce real scenes, with the Chinese side relying on precious footage from the August First Film Studio and the Pakistani side mainly using photographs; employing casualty data to establish factual authority, with the Pakistani side listing 567 military personnel and 246 civilian sacrifices with individual names recorded, and the Chinese side recording 168 martyrs; citing evaluations from the other country's ambassadors to elevate to the diplomatic level; and stimulating resonance through clear temporal脉络 and high-emotion details, with scenes such as rabies incidents, collapse accidents, and comrade memorials in the Chinese documentary being particularly infectious.

At the micro-writing level, both sides depict individual life practices within the interstices of grand narrative, restoring abstract "heroes" to concrete and perceptible ordinary people, penetrating cross-cultural communication barriers through universally shared human joys and sorrows, achieving emotional mobilization for "people-to-people connectivity."

III. The Media Function of the Karakoram Highway in the Perspective of China-Pakistan Community with a Shared Future

Within the perspective of the China-Pakistan community with a shared future, this section defines the Karakoram Highway as a giant spatial medium and "civilizational container" bearing political mutual trust, economic integration, and cultural connectivity. Through three dimensions of "spatial integration," "emotional resonance," and "risk-sharing," the highway constructs the material foundation and emotional bond of the China-Pakistan community with a shared future. In micro-level daily interactions, cross-cultural identity practices derived from the highway continuously consolidate the foundation of people-to-people connectivity between the two countries, such as Pakistani residents' guardianship of Chinese road workers' cemeteries and spontaneous farewell ceremonies, all transcending engineering employment relationships to form deep transnational emotional isomorphism. As infrastructure media, the highway breaks spatial enclosure, promoting the integration of Pakistan's northern remote areas into modern development networks, making small cities such as Gilgit regional trade centers, becoming physical symbols of coordinated development and shared prosperity between the two countries. Highway signage along the route constitutes "spatial inscription" of national memory, forming intertextuality with multilingual stone carvings of the ancient Silk Road, completing the contemporary extension of ancient civilizational convergence spaces. Spatial upgrading brought by technological evolution enables the highway's mission of cultural exchange to deeply integrate with modern economic and technical cooperation, becoming a typical case of regional community with a shared future construction under the Belt and Road Initiative. Facing natural disasters and sudden crises, the highway serves as a critical channel for transnational mutual assistance and risk-sharing; Chinese enterprises' substantive reciprocal behaviors in energy, transportation, education, and medical fields form powerful grassroots narratives in Pakistani grassroots society, generating endogenous "social resilience" through physical presence and evidence of livelihood improvement, objectively deconstructing Western media's negative discursive hegemony.

IV. Conclusion

This study explores the dual functions of the two Karakoram Highway documentaries as transnational media: they not only construct structured knowledge graphs through micro-narratives and intertextual dialogue to facilitate cross-cultural cognitive understanding, but also condense "shared weal and woe" collective memory within the "trauma-sublime" narrative structure to achieve deep regional identification. The study points out that the collectivist engineering rationality presented in the Chinese text and the indigenous subjectivity military mobilization mechanism presented in the Pakistani text jointly establish an equal co-construction paradigm for Global South cooperation, breaking through the hegemonic framework of Western infrastructure narratives. The cinematic writing reveals the value of infrastructure as a core spatial medium for "people-to-people connectivity," providing historical confirmation and discursive resources for the construction of the China-Pakistan community with a shared future within the Belt and Road framework.
