Why Did Russia and the EU Clash Over Ukraine in 2014, But Not Over Armenia?

Drawing on the theory of script formulations, this essay explores why, in 2013-2014, the EU and Russia clashed over Ukraine but not over Armenia by analysing the evolution of discursive dynamics and the attribution of accountability between both actors. It argues that the positions of Russia and the EU were not simply a function of a priori defined strategic interests and expectations but were codetermined by and through the events and actions of others. The essay contributes to a better understanding of the non-linear dynamics behind the escalation of tensions between the EU and Russia.
