Abstract
The contemporary transformation of conflict communication has situated encrypted messaging applications and channel-based platforms at the nexus of strategic statecraft and informational warfare. This study examines digital diplomacy during crises through an empirical case study of official governmental communication strategies on Telegram throughout the ongoing Russia-Ukraine conflict. Utilizing a mixed-methods research design that combines structural corpus analysis with qualitative framing, we analyze over 12,000 public broadcast messages deployed by verified Ukrainian and Russian state channels across an eight-month observational period. The findings illuminate divergent strategic postures: Ukrainian communications leveraged an affective, personalized, and multi-modal mobilization model characterized by real-time operational updates, leadership immediacy, and targeted international appeal, whereas Russian state communications deployed an institutionalized, legalistic, and deconstructive counter-framing strategy aimed at undermining multilateral credibility. Furthermore, the analysis demonstrates how Telegram's specific platform affordances—including unmoderated broadcasting, absence of algorithmic curation, and high forwarding velocity—have structurally altered crisis diplomacy, transitioning it from traditional soft-power persuasion into kinetic, real-time narrative defense. This article contributes an empirical framework for evaluating digital diplomacy under conditions of asymmetric geopolitical crisis and hybrid conflict.
