Fix the World Trade Organisation (WTO). Repair relations with the United States. Build a fair trading relationship with China. Work towards a trade agreement with Asean as well as the African continent. Deal with Brexit, if it happens, and then negotiate a post-Brexit deal with the United Kingdom. Ensure that the demanding provisions of the 43 trade agreements that the world's largest trading bloc, the European Union, has in place are actually enforced.
That's a partial to-do list, as of now, for the EU's next trade czar Phil Hogan, who takes up his post as Trade Commissioner on Dec 1.
