The European Commission is protesting against China's provisional measures on spirits, arguing they are inconsistent with WTO rules and unfair. China's duties on spirits range from 30.6% on Martell cognac to 39% on Hennessy and 38.1% on Remy Martin. China defends the duties as legal and necessary to protect its domestic industries. This dispute is part of a larger trade conflict between China and the EU, involving tariffs, subsidies, and protection of domestic industries.
