A recent WTO report finds that WTO members introduced fewer trade-restrictive measures from mid-October 2016 to mid-October 2017 compared to the previous year. At $169 billion, the import-facilitating measures adopted during the review period covered twice the value of the import-restrictive measures implemented, which totaled $79 billion. The initiation of trade remedy investigations remained the most frequently applied trade-restrictive measure at around 46% of the total, with the initiation of antidumping investigations accounting for 83% of all trade remedy initiations. India led the way with 55 new AD investigations during July 2016-June 2017, followed by the US (47), Argentina (21), Canada (19), Turkey (19), and Australia (18).
