International arbitration is a recognized way to resolve economic conflicts. This article asks if state-state investment arbitration (SSIA) is an option for Latin America. It examines the language of investment treaty provisions, cases and arbitral awards involving states, and treaty-making practice in the region. The analysis shows some complementarity between the mechanisms of investor-state arbitration (ISA) and SSIA; sometimes, the latter is the only option. This article concludes that SSIA is neither a backlash nor a more effective mechanism compared to ISA. SSIA constitutes an opportunity for both home and host Latin American states to balance their investment treaty commitments.

国家与国家之间的投资仲裁是拉丁美洲的旧选择吗？

国际仲裁是一种公认​​的解决经济冲突的方式。本文询问州与国家之间的投资仲裁 (SSIA) 是否是拉丁美洲的一种选择。它研究了投资条约条款、涉及国家的案件和仲裁裁决的语言，以及该地区的条约制定实践。分析表明，投资者-国家仲裁 (ISA) 和 SSIA 机制之间存在一些互补性；有时，后者是唯一的选择。本文得出的结论是，与 ISA 相比，SSIA 既不是一种强烈反对，也不是一种更有效的机制。SSIA 为拉美国家和东道国提供了平衡投资条约承诺的机会。
