Downing Street said the meeting with Lord Frost - held with less than
a week to go until the UK's deadline for agreeing a deal - had been
"useful".
But differences remained on important issues, a spokesperson added.
A No 10 spokesman confirmed that informal discussions would resume in Brussels next week.
"We have had useful discussions this week," the spokesman said.
"Progress
has been made in some areas, however there still remains differences on
some important issues but we remain committed to trying to agree a FTA
(free trade agreement).
"We continue to want an agreement, we continue to want an FTA but it is important that we can agree on some issues."
The talks came after European Council President Charles Michel said the sides were approaching "the moment of truth".
The
UK's post-Brexit transition period, during which its trading
relationship with the EU has remained the same, is due to end in
December.
