The UK government has established working groups and "high-level dialogues" with at least 15 countries, the Department for International Trade confirmed to IBTimes UK on Wednesday 29 March.
The news comes on the same day Prime Minister Theresa May plans to invoke Article 50 of the Lisbon Treaty and trigger Brexit talks with the EU.
The process will start once Sir Tim Barrow, the UK's chief representative to the EU, hand-delivers a letter to the EU Council.
The institution's president Donald Tusk has promised to reply within 48 hours and a summit of the 27 other EU leaders has been scheduled for 29 April.
The top politicians will decide on the guidelines EU Commission negotiator Michel Barnier and his task force are given for the two-year-long talks.
May has revealed that she will not seek to maintain the UK's full access of the EU's single-market and seek to barter a "unique" customs relationship with bloc, which will allow Britain to make its own free trade agreements – something that the UK, as a member of the EU, is not currently able to do.
As of 21 March, nine working groups and dialogues have been announced publicly. You can view those countries below.
