In France, arbitration, both domestic and international, has recently been subjected to a major reform. This article discusses the content of the 2011 reform and its aftermath, while putting into perspective the current arbitration act in South Korea, an arbitration-friendly jurisdiction that contemplates reforming its own law. The two legal systems are characterized by their concern for efficiency and rationalization of the arbitration proceedings, through the codification of essential principles previously established by case law and through the promotion of the independence of this ADR vis-$grave{a}$-vis state courts. The efficiency consideration is strengthened at every stage of the proceedings: from the arbitration agreement often considered valid and rarely challenged, through the proceedings for annulment, recognition and enforcement of the award, up to the judicial assistance of the French supporting judge towards the actual arbitral proceedings. Finally, new concerns are emerging: the increase of transparency and the arbitrability of disputes in some uncertain fields of law.
