Of course they'll have to let in EU exports, just like the EU will have to let in UK exports. Why? They're all members of the World Trade Organisation.
The EU is set up to allow the member countries to cooperate more closely, through lower trade barriers and suchlike. The idea that leaving the EU means zero trade is absurd.
It will probably also have to allow in EU exports which could threaten parts of their economy.
