"We would fight a WTO case and we believe we would win it," said EU spokeswoman Arancha Gonzalez. On Thursday, U.S. Trade Representative Robert Zoellick slammed the EU moratorium, calling it "immoral" and a "complete violation of WTO" rules. Some U.S. officials oppose raising tensions with the 15-nation EU and Zoellick said Washington still has to decide whether to file a WTO case. A high-profile trade dispute could backfire by strengthening sentiment against GM crops in Europe. The EU proposed new GM labeling and traceability rules last December. The EU Parliament still must approve them this spring.
