国际投资仲裁中国民待遇条款的“相似情形”问题研究

A Study on Like Circumstance of National Treatment in International Investment Arbitrations

国民待遇条款是双边投资协定的重要内容,其中对"相似情形"的解读是国际投资仲裁庭认定东道国是否给予外国投资者国民待遇的关键。受国际法碎片化的影响,不同的投资仲裁庭对"相似情形"的解读各不相同,导致适用国民待遇条款时存在诸多争议。通过分析近年来ICSID仲裁庭对"相似情形"的解读,可明晰目前其在解读"相似情形"时对比较量倾向的路径选择,以及不认定为"相似情形"的例外情形,这对于各国商签双边投资协定具有启迪意义。

National Treatment is one of the most significant substantial clauses in bilateral investment treaties(BITs).In the application process of national treatment,the interpretation of like circumstance plays a crucial role in the arbitral tribunal’s finding whether the host state’s treatment accords with national treatment.Influenced by the fragmentation of international law,different investment arbitral tribunals hold divergent views with respect to like circumstance,thereby giving rise to much debate in the application of national treatment.This thesis aims at clarifying the approaches and exceptions in the interpretation of like circumstance so as to shed light on inter-state BIT negotiations.
