Extraterritorial application of domestic competition law is an important feature of the current regulatory framework governing anticompetitive conduct. Japan was initially hesitant to apply its Antimonopoly Act in such a manner. However, over the last two decades there has been a significant shift in its approach. Japan has gradually embraced extraterritoriality and the Japan Fair Trade Commission has actively enforced competition law in a purely offshore context. This article investigates this evolution and considered the most recent and controversial cases in which Japan has applied its laws in a distinctive fashion.

In the absence of stringent and coordinated international action, States might seek alternatives to promote environmental protection unilaterally. Trade measures may be tools to promote environmental protection in other countries through the means of trade restrictions based on the process and production methods of a good (PPMs), but can they be used to protect global environmental concerns? PPMs are considered to be controversial because of their extraterritorial character. Inspired by other fields of law where an extraterritorial application of laws is accepted, such as competition law and international human rights law, this paper proposes a systematic approach to assess the acceptability of extraterritorial trade measures with an environmental objective within the scope of the general exceptions of the GATT. This contribution purports to answer whether the WTO forms a stumbling block for States to address global environmental concerns through trade.
