The adoption of social media platforms by news organizations invariably coincides with transformations in the production, expression, and acceptance of news as public knowledge claims. This study explores how a special subset of Chinese journalists-the foreign-aimed journalists-negotiate their epistemic authority while producing transnational news on foreign platforms. Drawing on 26 in-depth interviews, findings reveal four major tensions as Chinese journalists strive to negotiate authority among foreign audiences: reaffirming professional boundaries; navigating the management directives; maintaining a state messaging position; and understanding digital infrastructure. This study further contextualizes how, parallel to digital transformations, cultural transformations around journalistic knowledge claims are linked to historically and socially embedded priorities and constraints. The established conceptualizations of digital journalistic authority require expansion, as China's case illuminates the complex interplay between technology, politics, media regulation, and individual agency in shaping the epistemic landscape of contemporary journalism.
