As I understand it, the non-tariff barriers have been discussed so far at an EU level, given that the U.K. hasn't fully divorced itself from the EU rule book. It will, as I understand it, copy over the EU rule book on January 1. What we're hoping to see is that we'll be able to pick up those discussions with the U.K. as soon as possible at the beginning of next year because they have been a problem for businesses looking to take advantage of CETA in the EU-28.
On November 16th, 2020. See this statement in context.
