Senator Frances Black has urged the Government to move with urgency to enact the Occupied Territories Bill before the Summer recess.
She was speaking following a meeting today with Tánaiste and Minister for Foreign Affairs Simon Harris where they discussed her proposed legislation.
Ms Black said she reminded the Tánaiste that the Government had made a promise to the Irish people before the election and now was the time to deliver.
"Genocide is happening and children are starving and being killed. We can't have any more delays, we need this before the summer recess."
Also speaking after the meeting, the Tánaiste indicated that he would bring forward a Government Bill "within weeks" and ahead of the summer break.
He said he agreed to meet the senator again next week when he would present a timeline for enacting the proposed legislation.
The Bill will initially go for pre-legislative scrutiny at the Foreign Affairs Committee.
Ms Black also said that a full trade ban covering both goods and services is necessary.
The Tánaiste has indicated that his focus is on bringing forward a Bill banning trade in goods only.
Ms Black said there was no legal barrier to a full trade ban and her legal team had shared all its information with the Department.
Mr Harris rejected a suggestion from Social Democrats TD Sinéad Gibney that legislating only for a ban on goods would water down the intent of the Bill, rendering the move "meaningless".
"There is a view legally available to Government that there might a be a narrow way of moving forward on goods, but the way on services isn't as clear," he said.

'Grave concern'
Ireland and five other countries have issued a joint statement warning that Israel's plans to expand military operations in Gaza would cross yet another line and represent a dangerous escalation in the war.
The Foreign Ministers of Iceland, Ireland, Luxembourg, Norway, Slovenia and Spain said they wanted to express their "grave concern" about plans which they said would jeopardise the prospects of a viable two-state solution.
"A further military escalation in Gaza will only exacerbate an already catastrophic situation for the civilian Palestinian population and threaten the lives of the hostages that remain in captivity."
The statement also called on Israel to "immediately lift the blockade" to "facilitate relief for all civilians in need, without discrimination, and to follow the other humanitarian principles of impartiality, independence and neutrality".
Mr Harris, said he was working together with other countries to build a coalition to speak out against "the horrific development".
"The actions announced today will cause a scale of further catastrophe that is almost unimaginable in terms of the impact on civilians," he said.
"What the Israeli government is proposing is sickening, is despicable and is a clear breach of international law and does constitute a war crime."
Mr Harris also said he would write to the European Commission urging it to review the trade association agreement with Israel.
A similar letter from the previous Government has not been acted on.
