EU Trade Commissioner Peter Mandelson has warned Saudi Arabia that it would take WTO action if the Riyadh government supported a boycott of Danish goods, the European Commission said Monday. A Danish newspaper's publication of caricatures of the Prophet Muhammad has led to tension between Denmark and some Muslim countries. Mandelson told the Saudi Minister of State that any Danish boycott would be a boycott of the European Union. The Saudi minister told Mandelson that the government had not encouraged the boycott. Denmark told Riyadh that it did not support the incitement of racial hatred but could not condemn the free expression of the press.
