This article aims to examine the subject of remedies in international investment law under two competing theories of contracting which encompass different implications for contractual relationships. It first assesses the available remedies in existing international investment law and then looks at the approach taken by relational contract theory. The article addresses the inadequacy of the remedies suggested by the classical model (existing and dominant law) in maintaining equilibrium and restoring contractual balance in international investment contracts. In light of these analyses, the article attempts to determine and develop the features and availability of remedies suggested by the relational model in international investment agreements. It underlines that the suggested remedy according to relational theory would serve the joint purpose and interests of contracting parties.
