WTO Complaints against Chinese AD/CVD Measures

Two WTO complaints against Chinese AD/CVD measures seem to be going forward, as both the U.S. and EU have filed panel requests:

(DS425) China - Definitive Anti-Dumping Duties on X-Ray Security Inspection Equipment from the European Union

(DS427) China - Anti-Dumping and Countervailing Duty Measures on Broiler Products from the United States

Along with the (DS414) China - Countervailing and Anti-Dumping Duties on Grain Oriented Flat-Rolled Electrical Steel from the United States case already underway, is this a new trend in WTO dispute settlement?  Will other countries start bringing complaints as well?
