An agreement that would commit Britain to maintaining "regulatory alignment" between Northern Ireland and Ireland after Brexit would make it easier to avoid a hard border but limit the UK's ability to change its economic regulations to strike new trade deals across the world.
The concession has yet to be accepted by the Irish government.
Ms Foster had issued a statement warning it would not accept "any form of regulatory divergence which separates Northern Ireland economically or politically from the rest of the UK".

US, China held rare security meeting after North Korea launch

It is understood this is a sticking point in reaching a deal on post-Brexit citizens' rights, the part of the phase one divorce negotiations that had previously been considered to be the most advanced. But Ireland and the other EU nations are demanding to know how that will work if Britain is outside the EU's borderless single market and its tariff-free customs union, a looser trading bloc that includes non-EU states like Turkey.

If she had ignored their concerns, there's little doubt that the party's 10 MPs would have sat on their hands and not supported the Conservatives in important votes on the EU Withdrawal Bill this week. But she said talks would reconvene later this week "and I am also confident we will conclude this positively".
"It is now getting very tight but agreement at December (summit) is still possible", he tweeted.
"And the problem between the Republic and Northern Ireland is a outcome of the British decision not only to leave the EU but also the single market and the customs union".
