The proliferation of international fora over the past decades has created a dynamic in which international actors can no longer approach diplomacy in singular fora in isolation. This carries significant implications for the ways in which actors pursue their objectives at the international level in issue areas like trade, security, and climate change, among others. Although the literature has mainly focused on ways in which actors can select or modify existing fora of a regime complex to best serve their interests, it is indeed likely that the potential for strategic action also extends to multilateral negotiations inside a regime complex, which remain a key part of the global governance landscape. This paper answers the research questions: What conditions determine how an actor connects its activity across a regime complex in support of its objectives in a specific negotiation? To do so, it examines the diplomacy of the European Union (EU), an established international actor with leadership ambitions in climate, relating to four multilateral climate agreements negotiated in 2015 – 2018 (Paris Agreement, ICAO CORSIA, Kigali Amendment, and IMO Initial Strategy) within the International Regime Complex on Climate Change (IRCCC). Based on a triangulation of official documents and 43 semi-structured interviews, it identifies combinations of conditions that explain the ways in which an actor connects its activity across a regime complex in support of its negotiation objectives in a given forum. It finds that alignment between an actor’s internal policy-making venues explains the use of connections in a given non-focal forum and that actor-specific and regime complex-related conditions explain the specific types of connections an actor uses.
