摘要:Given that the inherent feature of confidentiality and the demands for transparency coexist in the context of international investment arbitration, this work focuses on an approach towards a compromise of these two categories. From the perspective of the principle of transparency in the field of international economic law, and taking into account the nature of international arbitration -specially international investment arbitration- a defendable argument shall be uncovered in order to overlook the need for confidentiality and satiate the demands for transparency in the investment arbitration procedure without impairing its efficiency.
