Abstract China has initiated three antidumping (AD) investigations against US feed products since 2010, despite clear mutual benefits from such exports from the US to China. This article provides a close examination of these investigations, what prompted them, how they were resolved, and the costs they imposed on importers and exporters. The article also describes the political economy around these investigations and how China's antidumping laws provide it with flexibility to manage these investigations. The article concludes that this flexibility makes China well-positioned to continue using AD investigations against some trade partners in the future, particularly if AD use continues to rise globally.
