THE border backstop is not a trap to ensnare the UK or Northern Ireland, Tánaiste Simon Coveney has said.
Mr Coveney also said the insurance mechanism was not designed to bring about constitutional change.
The Republic's minister for foreign affairs said: "We don't want the backstop for it to be some kind of trap in which to ensnare and hold the UK or Northern Ireland.
"Nor do we want the backstop as some kind of stepping stone to changing the constitutional status of Northern Ireland."
Mr Coveney made the comments during a speech at Queen's University Belfast on the second anniversary of the collapse of Stormont power-sharing.
He said the Dublin government did not want to see the backstop invoked at all.
"The backstop is there to ensure that in no circumstances can there be a hard border – something that nobody wants," he said.

"We have a collective responsibility to avoid that outcome.
"Legal clarity is therefore required."
If ratified, Mr Coveney said the Withdrawal Agreement would pave the way for "positive" and "ambitious" discussions on the future relationship.
He added that the Irish government shared the UK's desire for a deep and comprehensive future relationship agreement that avoids a hard border to be decided by the end of 2020.
The backstop, enacted if a wider UK-EU trade deal fails to materialise, would see the north continue to adhere to some EU rules.
It is designed to maintain a free-flowing border in Ireland regardless of the outworking of Brexit, but the DUP and other Brexiteers claimed it would undermine the constitutional integrity of the UK by creating barriers between Northern Ireland and Britain.
Addressing the lack of a functioning government in the region for two years, he said: "The ongoing failure, not just to restore the assembly and executive to full operation, but even to come together again and restart negotiations, is unacceptable."
Mr Coveney said it was very important that the people of Northern Ireland should have a voice through their elected representatives during the Brexit negotiations.
"This is exactly one of the reasons we need the assembly and executive up and running again – and to be working well," he said.
"We shouldn't underestimate the impact that Northern Ireland's leaders speaking with one voice on key concerns could have.
"And if the backstop were ever to be used, their voices should be heard at that stage too.
"We need the parties to come together and talk now about how to restore an assembly and executive together, as well as fully functioning north-south institutions.
"It's not easy but it's been done before and I think there is a recognition it will need to be done again."
