Speaking alongside the Arab country's ruler in the White House, Trump signalled he would not budge on his idea that involves moving the Gaza Strip's shell-shocked residents and transforming the war-ravaged territory into what he billed a "Riviera of the Middle East."
Trump has infuriated the Arab world by saying that Palestinians would not be able to return to their homes under his proposal to redevelop the enclave, which has been devastated by an Israeli offensive.
"We're going to take it. We're going to hold it, we're going to cherish it. We're going to get it going eventually, where a lot of jobs are going to be created for the people in the Middle East," Trump said in the Oval Office, saying his plan would "bring peace" to the region.
King Abdullah said later that he reiterated to Trump Jordan's "steadfast position" against the displacement of Palestinians in Gaza, as well as in the occupied West Bank that borders his country.
"This is the unified Arab position," he said in a post on X. "Rebuilding Gaza without displacing the Palestinians and addressing the dire humanitarian situation should be the priority for all."
Despite the views of his Jordanian counterpart, Trump said Jordan, as well as Egypt, would ultimately agree to house displaced residents of Gaza. Both countries rely on Washington for economic and military aid.
"I believe we'll have a parcel of land in Jordan. I believe we'll have a parcel of land in Egypt," said Trump. "We may have someplace else, but I think when we finish our talks, we'll have a place where they're going to live very happily and very safely."
Trump, who has suggested he could consider withholding aid to Jordan, said he was not using support as a threat.
"We contribute a lot of money to Jordan, and to Egypt by the way - a lot to both. But I don't have to threaten that. I think we're above that," Trump said.
King Abdullah is the first Arab leader to meet Trump since the Gaza plan was floated.
Trump at one point appeared to prompt King Abdullah to say he would take in Palestinians from Gaza. The king said he would do what is best for his country, but said Jordan would take in 2,000 sick children from Gaza for treatment, an offer that Trump praised.
Arab nations would come to Washington with a counterproposal, the Jordanian leader said.
"The point is how to make this work in a way that is good for everybody," he said, appearing uncomfortable, without explicitly supporting or opposing Trump's plan.
Jordanian Foreign Minister Ayman Safadi later told state-owned al-Mamlaka TV that there is an Egyptian-led Arab plan to rebuild Gaza without displacing its people.
Sandwiched between Saudi Arabia, Syria, Israel and the occupied West Bank, Jordan is already home to more than 2 million Palestinian refugees in its population of 11 million, their status and number long providing a source of anxiety for the country's leadership.
Amman is also reeling from Trump's 90-day aid pause. Israel and Egypt have been granted waivers, but the $1.45 billion Jordan gets each year remains frozen pending a Trump administration review of all foreign aid.
Trump's proposal has introduced new complexity into a sensitive regional dynamic, including a fragile ceasefire between Israel and the Palestinian militant group Hamas.
Hamas on Monday said it would stop releasing Israeli hostages from Gaza until further notice, saying Israel was violating the agreement to end strikes that have pummelled Gaza.
Israeli Prime Minister Benjamin Netanyahu said the ceasefire in the Gaza Strip will end if Hamas does not return more hostages held in the enclave by noon on Saturday - a deadline also expressed by Trump.
"The military will return to intense fighting until Hamas is finally defeated," Netanyahu said in a video statement.
Three out of four Americans -- 74 per cent -- in a Reuters/Ipsos poll conducted February 7-9 said they opposed the idea of the US taking control of Gaza and displacing the Palestinians who live there. The poll showed that Republicans were divided on the issue, with 55 per cent opposed and 43 per cent supportive.
