Earlier this week, Israeli Prime Minister Benjamin Netanyahu questioned Abbas's motivations.
But there can not be lasting peace unless the Palestinian leaders speak in a unified voice against incitement to violate - and violence and hate.
"We believe that we are capable and able to bring about success to our efforts, because, Mr. President, you have the determination and you have the desire to see it become to fruition and to become successful".
"There can not be lasting peace unless the Palestinian leaders speak in a unified voice against incitement to violate - and violence and hate", Trump said.
Palestinian leader Mahmoud Abbas speaks in the Roosevelt Room of the White House in Washington, Wednesday, May 3, 2017, where he and President Donald Trump spoke.
President Trump shakes hand with Palestinian Authority President Mahmud Abbas in the Oval Office of the White House on Wednesday. "We will be working so hard to get it done".
US Vice President Mike Pence contended ahead of the meeting that the White House is "seriously considering" moving the US Embassy in Israel from Tel Aviv to Jerusalem. "Mr. President, it's about time for Israel to end its occupation of our people and of our land after 50 years". "You know, he wants to broker a peace deal, but there is a danger to orchestrating yet another peace process".More news: Men's New Mutants Movie Casts Split And Game Of Thrones Stars
But he repeatedly praised Trump, saying that he was "looking forward to working with" him "toward a historic peace deal" and lauded the commander-in-chief for his "courageous stewardship and wisdom" and his "great negotiating abilities".
Trump emphasized that his administration wants to advance the Palestinian economy and "help unlock the potential of the Palestinian people" through job creation and private initiatives. The Israeli Central Bureau of Statistics said the number of Jewish settlers in disputed territory grew from 198,300 in 2000 to 385,900 in 2015. "I'd like to see you hold back on settlements for a little bit", Trump told Netanyahu, even though the Israeli leader said he doesn't see settlements as the "core of the problem".
Abbas needs Trump's support to legitimize his power, and Ross encouraged Trump to press Abbas to make concessions, such as ceasing sending money to jailed Palestinians who had killed Israelis.
But Trump's commitment was met with skepticism in diplomatic quarters, coming just two months after he broke with the longstanding US policy of advocating a two-state solution, and vowed to move the US Embassy to Jerusalem, breaking with US policies that have lasted decades.
Trump was set to have dinner with religious leaders at the White House Wednesday evening, ahead of an expected signing of an executive order on religious liberty.
Pence said Trump is "personally committed to resolving the Israeli and Palestinian conflict" and "valuable progress" is being made.
Abbas, for his part, continued the Palestinian Authority's long-held position that a long-term peace agreement requires a separate Palestinian state, bounded by territorial borders as they were in 1967 and with East Jerusalem as its capital.
