After the UK’s withdrawal from the European Union (EU), the EU’s trade defence measures no longer applied to the territory of the UK. This means that the UK now applies its own trade defence measures and has transitioned some of the EU’s trade defence measures. The EU applies its trade defence measures to the reduced territory of the EU27, while third parties that had imposed trade defence measures against the EU now apply them against the EU27 and the UK. This article analyses the compatibility of these changed measures with WTO law. It argues first that in principle WTO law allows changes in the territorial scope of trade defence measures if the investigation and imposition of the measures remain attributable to the imposing WTO Member. This defends the EU’s and the UK’s approaches. Second, changed circumstances’ reviews or adaptations of the measures by the EU or the UK may be necessary. However, this happens rarely and only if specific evidence is provided. Third, subject to review or adaptations where warranted, third countries can apply their measures targeting the EU against the EU27 and the UK.

英国脱欧与贸易防御：领土变化的影响

英国退出欧盟后，欧盟的贸易防御措施不再适用于英国境内。这意味着英国现在实施了自己的贸易防御措施，并且已经过渡了欧盟的一些贸易防御措施。欧盟将其贸易防御措施应用于欧盟 27 国减少的领土，而对欧盟实施贸易防御措施的第三方现在对欧盟 27 国和英国实施贸易防御措施。本文分析了这些改变措施与 WTO 法律的兼容性。它首先辩称，原则上，世贸组织法律允许改变贸易防御措施的地域范围，前提是调查和实施措施仍可归因于强权的世贸组织成员。这为欧盟和英国的做法辩护。第二，欧盟或英国可能需要对变化的情况进行审查或调整措施。然而，这种情况很少发生，只有在提供具体证据的情况下才会发生。第三，在必要时进行审查或调整，第三国可以针对欧盟 27 国和英国采取针对欧盟的措施。
