Over the past couple of decades, we can see the emergence of a new lex mercatoria. It consists of international conventions or treaty, model laws and international principles. And such new lex mercatoria is driven by the international institutions such as UNCITRAL, UNIDROIT and ICC. The international convention and international principles in the field of international commercial transaction are considered : UN Convention on Contracts for the International Sale of Goods(CISG) and The UNIDROIT Principles(PICC Principles). The former is the statue law for the latter, and the latter sometimes supports the former as an interpretation and supplementation of CISG. So, the purpose of this article is to evaluate and investigate the current status of CISG and PICC Principles in terms of application and interpretation principles. The results are as follows. First, PICC are used for the interpretation and supplementation of international law such as CISG, but CISG is a law, not a rule. Second, CISG and PICC Principles are not often chosen when parties chose the law governing their contract. The parties very often chose a national law ; the number of the parties choosing CISG and PICC Principles as a governing law was very low.

The International Institute for the Unification of Private Law (UNIDROIT) established UNIDROIT principles, which could be applicable as international unified rules. The UNIDROIT Principles plays the role of interpreting and complementing CISG and functions as a law applicable to international commercial disputes. As shown by cases of practical application so far, the principles are expected to be applied frequently to international commercial arbitration in the future. In the situation that there is no internationally unified judicature, it is necessary to promote rational dispute resolution and legal stability through arbitration by adopting the UNIDROIT Principles of Lex Mercatoria as a governing law of international commercial contracts. In conclusion, UNIDROIT principles, along with CISG, are expected to playa great role as the applicable law of international commercial contracts and as standards for resolving international commercial disputes.
