国际实践证明,国际投资仲裁是一个相当成功的争端解决制度。但是,随着投资仲裁平行程序的出现,冲突或不一致裁决的出现使得投资仲裁制度前景堪忧。一方面,不可否认,国际投资协定的制度建构在一定程度上导致了国际投资仲裁平行程序的出现;但另一方面,国际投资协定中的相关条款设计同样可以预防投资仲裁平行程序的出现,并起到未雨绸缪的效果。 International practice has proved that international investment arbitration is a fairly successful dispute settlement system. However, with the advent of parallel procedures for investment arbitration, the emergence of conflicts or inconsistent rulings made the future of investment arbitration a bleak prospect. On the one hand, it is undeniable that the construction of the IIA system has, to some extent, led to the emergence of parallel procedures for international investment arbitration. On the other hand, the design of relevant provisions in IIAs can also prevent the parallel process of investment arbitration from occurring and, Play a precautionary effect.
