This article examines the impact of digital globalization on cultural reorientation in contemporary Vietnam. Drawing upon perspectives from digital anthropology, globalization studies, media studies, and cultural sociology, the study analyzes how social media platforms, online communication, and transnational digital culture reshape community interaction, identity formation, and cultural values within Vietnamese society. Since the rapid expansion of internet access and smartphone usage after the mid-2000s, platforms such as Facebook, TikTok, YouTube, and Instagram have increasingly become important spaces of cultural production and mediated social interaction. The findings demonstrate that digital globalization contributes to the transition from territorially bounded local communities toward more networked, flexible, and translocal forms of belonging. Vietnamese youth increasingly construct identity through digital participation, symbolic consumption, online aesthetics, and transnational media engagement, generating hybrid cultural practices that combine local traditions with global influences. At the same time, online communication reshapes cultural values, social interaction, and symbolic hierarchies through influencer culture, digital consumerism, and platform-mediated participation. However, the study argues that digital globalization does not simply homogenize culture. Instead, Vietnamese users actively reinterpret and localize global digital flows within specific social and cultural contexts. Consequently, contemporary Vietnamese culture increasingly operates through mediated, negotiated, and hybrid forms of digital interaction within globally connected environments.
