在当代国际商事仲裁中,除了特定国家的内国法体系以外,“非国内”规则(denational rules)也经常作为仲裁实体法被当事人或者仲裁庭选择适用,以解决国际民商事纠纷。中国的1994年《仲裁法》并没有对涉外仲裁,即国际商事仲裁实体法的适用作出明确规定。因此在中国的国际商事仲裁中适用“非国内”规则在理论和实践中都存在争论和模糊不清之处。 In contemporary international commercial arbitration, except for the legal system of a specific country, the “non-domestic” denational rules are also often used as arbitration substantive law by parties or arbitration tribunals to solve international civil and commercial disputes. China’s 1994 Arbitration Law did not make any explicit stipulations on the application of foreign-related arbitration, that is, the substantive law of international commercial arbitration. Therefore, the application of “non-domestic” rules in international commercial arbitration in China is controversial and vague in both theory and practice.
