国际法在一般商事仲裁中不具有适用性,但在国际投资争议仲裁中的适用已得到了认可。然而主张国家契约必须受国际法支配的观点,是不能令人接受的。在国家契约中选择适用“共同法律原则”则是一个进步,资本输出国和资本输入国对此都不应采取绝对化的观点。 International law does not have applicability in general commercial arbitration, but its application in the arbitration of international investment disputes has been approved. However, the argument that a national contract must be governed by international law is unacceptable. The choice and application of the “common law principle” in the national contract is an improvement, and neither the capital-exporting country nor the capital-importing country should take an absolute view.
