AbstractThe 2003 US-Chile free trade agreement, regarded by many as consistent with Chile's long-held trade liberalisation strategy, nonetheless engendered a surprisingly vigorous debate focused on the proposed elimination of the bandas de precio protecting traditional agricultural crops. Opposition to the agreement, mounted by the conservative Alianza por Chile, offers an intriguing political case study that suggests that populist posturing surrounding free trade agreements may persist long after a trade liberalisation strategy has become well-established. This article argues that agricultural liberalisation will be a significant challenge for Chile's governing coalition if it wishes to pursue trade negotiations while seeking to avoid costly political battles at home over the economic costs of abandoning price supports and the challenges of ‘reconverting’ to an export-oriented sector. Even given the strong elite consensus around trade liberalisation in Chile, the interconnections between sectoral interest groups, domestic politics and trade negotiations remain relevant, and deserving of analytical attention.
