Ireland is "not going to wait for consensus" from other European nations in relation to trade with Israel's illegal settlements, Taoiseach Simon Harris has said.
It comes as the three Government party leaders have been told by the Attorney General that there is now a new context to examine the Occupied Territories Bill.
The bill would ban trade between Ireland and Israel's illegal settlements in the Occupied Palestinian Territories.
The bill was introduced by Independent Senator Frances Black and has previously got Dáil and Seanad backing.
In recent weeks, Mr Harris requested updated legal advice on the Bill.
Attorney General Rossa Fanning now believes the International Court of Justice (ICJ) advisory opinion gives stronger legal grounds to look again at the Bill.
The Government party leaders heard that complex legal issues still remain and many changes might be required before the bill is enacted.
Formal written advice will be presented to the Cabinet next week and this is being taken as a signal that the Bill is now progressing.
Speaking on his way into a Cabinet meeting, Mr Harris said he would like the current Government to make progress on this issue.
"Tomorrow, I will attend the European Council, and my message to European leaders will be very clear, we're not going to wait for everyone in Europe to develop a consensus on this.
"If there's more Ireland can do, Ireland will absolutely not be found wanting, and I'd be willing to work with people across the political divide in relation to this," he said.
"I would like this current Government to make progress on this," Mr Harris added.
The Taoiseach said there has not been majority support in Europe for ending trade with Israel.
"It's always been my preference to move at a European level in relation to this.
"Myself and my Spanish counterpart, Pedro Sanchez, have consistently raised at the European Council table the need for Europe to move in terms of ceasing trade with Israel until there's a ceasefire and an end to this violence.
"There has not been majority support for that in Europe."
Senator Frances Black said she welcomed the move but said she still needed to see the full details.
Speaking to RTÉ's Today with Claire Byrne, she said: "What has been said so far is positive and encouraging."
She said that the existing bill was "ready and waiting" and added it should be passed urgently.
"If the Government want to respect the ICJ judgement and act, the quickest way to do this is to pass the Occupied Territories Bill.
"If we need to make small changes or amendments to strengthen or improve it, we can," she said.
Tánaiste Mícheál Martin said his department will prepare a memorandum in relation to a path forward for the bill for next week.
Also speaking on his way into the Cabinet, he said the existing bill would need to be redrafted and amended substantially.
"My department will prepare a memorandum for next week in respect of a pathway forward in respect of the occupied territories bill, in the context of the International court's advisory opinion, which, as I said some time back, has changed the situation in so far as it puts obligations on Member States not to do anything that would support the illegal occupation of Palestine.
"The International Court of Justice identifies the occupation in Palestine as illegal and says states should not do anything that would support it.
"So that offers a more clearer way forward, although there are still challenges and the existing bill would need to be redrafted and amended very substantively given the advice we have received," Mr Martin said.
O'Gorman hoping for progress by next week
Green Party leader Roderic O'Gorman has welcomed the latest advice from the Attorney General.
He said it is the view of the Green Party that Ireland would ban trade with the occupied territories.
He said he wants to see Ireland advance the Occupied Territories Bill in the lifetime of this Government.
Mr O'Gorman said he hoped there could be a plan to move forward on this issue by next week.
"Its the Green Party's position that Ireland shouldn't be trading with the occupied territories and we want to see that position advanced in the remaining lifetime of this Government.
"The Attorney General will be providing the three leaders with written advice later this week, and I hope that we'll be in a position to bring a plan as to how we go forward to Cabinet soon, maybe as soon as next week," he added.
