The WTO launched a new trade monitoring database, which provides detailed information on trade measures implemented by WTO members and observers since October 2008.
From the WTO Web Site:
The database will be updated each time a new trade monitoring report has been discussed by WTO members. The most recent update was completed on 15 October 2012. The next is expected at the end of July 2013.
The information contained within the database can be displayed in a number of ways, including by implementing country, by country affected by the measure, by type of measure, and by products affected.
