Minister for Finance Paschal Donohoe has said that he understands the fears that some people in the unionist community have expressed about the backstop.
Mr Donohoe said the Government takes such concerns very seriously, but the backstop should not be viewed as a challenge to unionism.
Speaking at a Dublin City University event on Brexit, he said the purpose of the backstop is to provide certainty to businesses and communities on both sides of the border that they will be able to continue operating and going about their daily live.
The minister said that it represents a compromise, and is not the same as Northern Ireland remaining in the European Union.
He added that the Government has always been prepared to look at modifications, improvements or alternative arrangements that would secure the same outcome.
"It is clear that a no-deal Brexit is bad for everyone on these islands, and everyone involved is working very hard to avoid that," Mr Donohoe said.
"It is equally clear, as Arlene Foster has said in the past, that a solution has to recognise the unique geographical and historical situation of Northern Ireland."
He went on to say that in the spirit of the Good Friday Agreement, the Government is working to reconcile the interests of both unionism and nationalism.
"In the absence of a solution, our work with the European Commission has intensified with the goal of at least avoiding physical infrastructure at the border in the event of a no deal Brexit," Mr Donohoe said.
But the minister warned there should be no doubt that if the UK decides to leave the EU without a deal, the risks for Northern Ireland and the Good Friday Agreement are very significant.
