Arlene Foster has met with Taoiseach Leo Varadkar in Dublin.
The newly elected Irish premier is to meet with both the DUP and Sinn Fein on Friday to discuss efforts being made to resurrect the Stormont power-sharing institutions.
The meeting comes as all five main Northern Ireland political parties held discussions with Prime Minister Theresa May in Downing Street.
The Conservative leader discussed her party's deal with the DUP, as well as meeting with Arlene Foster's party. An announcement is expected to be made on the tie-up between the two parties in the coming days.
At Friday's meeting with Mr Varadkar, the two parties are also expected to discuss the impact Brexit could have on the island.
It's one of the oldest cliches in the book, but a week really is a long time in politics. Exactly seven days ago the election in Northern Ireland looked set to throw up another dose of the same old, same old.
