On 14 January 2020 the United States, the European Union, and Japan (hereinafter referred to as “US-EU-Japan”) issued a trilateral joint statement, proposing a set of new rules to strengthen WTO regulation on industrial subsidies. While a total of seven joint announcements have been made so far, this is the first time that three WTO Members have presented specific ideas on how to amend existing subsidy rules. Many of the proposed amendments seem to primarily target China’s trade policy and practices. Among the six amendment items proposed in the Joint Statement, it seems that the United States is paying particular attention to the sixth item, i.e. in making explicit the possibility of using the out-of-country benchmark and on introducing necessary requirements to do so in measuring the benefit conferred and, ultimately, in calculating the amount of the countervailing duties (CVDs). Against this backdrop, in this Brief the author analyzes the relevant WTO provisions and GATT/WTO jurisprudence, and discusses various scenarios on future negotiations on WTO Reform on industrial subsidies.
