Recent literature has underscored the power of digital activism, but few studies have symmetrically examined its impact beyond domestic audiences and among illiberal regimes. The co-occurrence of mass protests in East and Southeast Asia in 2019–2021, when protesters called for help from international communities, offers a valuable opportunity to test the power of digital media. This study uses a data set of 154 million Twitter posts and a time-series model to contrast sets of collective action metrics and connective action metrics with a novel dependent variable—foreign politicians’ responses. We then analyze the directional, intensity, and time-lagged effects of the relevant cue-taking processes. We find that the new metrics are more potent in predicting responses from foreign politicians. Agency- and network-centered metrics also outperform number- and intensity-oriented metrics across the three cases. These findings have implications for the roles of opinion leadership and engagement networks in digital activism.
