BRUSSELS - European Commission spokeswoman Beate Gminder was quoted as telling a daily news briefing Friday that "We very much regret this decision," referring to the United States' decision to launch a trade suit against the EU's refusal to accept most genetically modified organisms (GMOs), adding, "It has not yet been decided whether the WTO will set up a panel, but we think that our system of GMO authorisation is clear, transparent and non-discriminatory and complies with WTO rules."
