The Taoiseach has said he will continue to listen to unionist concerns around the Northern Ireland Protocol.
Leo Varadkar made the comments in an article in this morning's Belfast Telegraph.
He said he would visit soon for talks with political leaders and urged the restoration of the Stormont institutions which have now been down for 10 months.
The DUP has refused to participate in the Executive after May's election in opposition to the protocol.
Mr Varadkar said the protocol was designed to protect the EU's Single Market while preventing the return of checks on the border.
Under the agreement, the checks are instead carried out at ports in Britain and Northern Ireland.
Unionists say the new arrangements have hampered trade between Britain and Northern Ireland and weakened its constitutional links with the rest of the UK.
Mr Varadkar cited recent statistics that showed sales growth for Northern Ireland firms who have unique access to both the British and EU markets.
He quoted other figures that showed an increase in sales by British firms to Northern Ireland since the protocol began.
The Taoiseach said he would continue to engage with all sides and try to assuage unionist concerns.
"We have listened and we have heard the concerns, in particular the concerns of unionism, about the protocol. I will continue to engage with and listen to those concerns," Mr Varadkar said.
"I am also conscious of the voice of businesses, many of which see the value of the protocol," he added.
He said he would build on the Shared Island Initiative which has provided £160m (€180m) for infrastructure projects in Northern Ireland.
Mr Varadkar said he remained confident that the EU and UN could finalise a deal in the protocol in the months ahead.
"There is an opportunity now for the EU and UK to reach an agreed way forward on the protocol which answers those concerns, building on the determination in the protocol that it should impact as little as possible on the everyday life of communities in Ireland and Northern Ireland," he said.
"However, let us be in no doubt that unilateral action by anyone will not bring the stability and certainty that the people of Northern Ireland want and need," he added.
