The relationship between international investment and human rights represents a troublesome matter to States that must balance compliance with their international obligations under human rights instruments with the protection of the interests of the investors guaranteed by international investment agreements. This chapter examines cases involving Latin American countries, drawing parallels between the different approaches used by the Inter-American Court of Human Rights and investment treaty arbitral tribunals in disputes that involve both foreign investment and human rights. Closely examining the La Oroya and Renco cases against Peru and the Chevron/Texaco and different human rights cases against Ecuador, we examine whether there is an interaction between both fora, either competitive or collaborative, or if they are in contradiction or isolation. To provide a comparative perspective, the Yukos cases against Russia, brought both before the European Court of Human Rights and several investment arbitral tribunals, are briefly addressed.
