This article foregrounds the great translation movement (GTM), initially mobilised on X (formerly Twitter) in response to the Russian invasion of Ukraine, as an example of activist journalism countering China's 'mainstream' narrative of the war and its broader implications. Using Fairclough’s dialectical-relational approach, adapted to the specifics of social media communication, we examine GTM postings throughout the first calendar year of the war, highlighting how the GTM evolves into a broader activist-journalistic initiative that challenges the party-state beyond its involvement in (...) the war. This paradigm of intervention unfolds as GTM activists report on evidential events within China that bear the potential to spark public contention outside of the party-state’s censorship reach. By examining the dialectical relations between reportage and advocacy, this analysis demonstrates how activist journalism constitutes an emerging cross-border civic engagement, challenging a Southern authoritarian regime from the outside. A critical evaluation of activist journalism and its broader societal impacts is also provided, highlighting its progressive potential and future development in the Chinese context and beyond.
