David Frost, the UK government's chief negotiator, and his EU counterpart Michel Barnier had a "useful review of the whole agenda before our talks" during informal Brexit discussions on Tuesday, Xinhua news agency quoted the spokesman as saying on Wednesday.
The UK formally left the EU on January 31 and is now in a pre-agreed period of transition during which it is free to open up trade talks with countries around the world.
Brexit was originally scheduled for March 29, 2019, but was repeatedly delayed when MPs rejected a previous withdrawal agreement reached by the EU and former Prime Minister Theresa May.
The Brexit issue is threatening to hurt Labour in its traditional working-class heartlands, which mostly voted to leave the EU.
