EU takes China to WTO in fresh tariff row In a statement headlined "EU Joins Japan in WTO Challenge," the European Commission said it believed the Chinese anti-dumping duties were "incompatible with WTO law, both on procedural and on substantive grounds. The Commission said the anti-dumping tariffs levied at 9.7pc to 11.1pc "are significantly hampering access to the Chinese market." The EU move raises the stakes in a series of tit-for-tat disputes with China, despite bilateral trade worth hundreds of billions of euros, AP reported. In addition to the steel tubes dispute, Beijing has launched anti-dumping action into imports of EU wine and chemicals after the EU imposed punitive tariffs on Chinese solar panels and threatened an investigation into China's key telecom equipment firms. EU-China trade ties are to be discussed Friday when EU trade ministers meet in Luxembourg.
