The leaked EU Brexit document comes after Barnier agreed to meet the Scottish Parliament's European Commission for an update on how negotiations with the UK Government are going.
The paper adds that the Good Friday Agreement needs to protected "in all its parts" - including the Common Travel Area and avoiding a hard border.
The Northern Ireland peace process could be put at risk if the government fails to reach a "sensible agreement" with the European Union over the border, a former head of the diplomatic service has warned.
"We welcome the opportunity to discuss the points that have been made to us in the evidence we have taken so far and to raise our concerns about the impact of Brexit in Scotland".

The UK has argued that especially the Ireland question can not be disentangled from other issues, such as customs and future trade deals, and therefore these negotiations should run in parallel. Once there is sufficient progress on the principles set out in today's paper, discussions may move to the second phase of negotiations, which aim to find flexible and imaginative solutions to avoid a hard border on the island of Ireland.
