This article examines the role of Pedro Ibáñez Ojeda – a prominent Chilean politician and businessman – in the development of Chilean neoliberalism, with a focus on his international networks and the organisation of the Mont Pelerin Society (MPS) regional meeting in Viña del Mar, Chile, in 1981. I argue that Ibáñez represented a distinctive pathway within Chilean neoliberalism, here termed the ‘coastal route’, which highlights the movement’s multi-scale and polycentric nature. This route is multi-scale in Ibáñez’s promotion of liberal ideas through interconnected national, Latin American and global actors, and polycentric in showcasing independent yet complementary initiatives that collectively shaped Chile’s neoliberal trajectory. These dynamics position Ibáñez’s route as part of a broader Latin American and global community.
