She said the us will not change its decision on December 6 to move the USA embassy to Jerusalem, a move that has frozen U.S.
Palestinian spokesman Nabil Abu Rudeina said Abbas would center his speech around "Al-Quds", or Jerusalem, and on basic Palestinian principles.
The Palestinian leader landed at Baltimore-Washington International Airport on a Boeing 737 at 3:00 p.m. after a flight from White Plains, New York, according to the Flight Radar24 site.
Addressing Abbas, who had already left the chamber, Haley said: "You don't have to like that decision but know this, that decision will not change".
It was only Abbas' second appearance before the Security Council, after a 2011 visit in which he advocated Palestinian statehood.
In his speech, Abbas will also propose ideas to the security council on how to counter President Donald Trump's decision to recognize Jerusalem as Israel's capital, move the US embassy to the occupied city, close the Palestinian delegation office in Washington and cut aid to the Palestinians through the United Nations refugee agency.
Grant Rumley, a research fellow and expert on Palestinian politics at the Foundation for Defense of Democracies, told JNS that he believes this was a legacy speech for Abbas.
"Today, the situation of the US and Israel indicate their fear of the Zionist regime's collapse and the USA decline". Until Trump, Abbas was able to chip away at Israel's vital interests.
Trump urges ban on gun devices like bump stocks
More broadly, the Department of Justice can't just ban such devices , its own officials have said in recent months. On October 1, 2017, a gunman had killed 59 people at a concert using bump fire stocks .
In another sign that peace efforts could soon be back on track, Abbas called for a multilateral peace conference this summer that would include the United States in a leading role.
Abbas presented the Palestinians "peace plan" to the council.
Abbas's speech comes amid ongoing tensions between the Palestinians and Washington, with Abbas stating that he no longer considers the United States to be an "honest broker" in Mideast peace and calling for an alternative to the US -led process.
"We believe negotiations are the only path towards peace, so how can we reject negotiations?" he said.
Secretary-General Antonio Guterres said that only a two-state solution would work and there was no Plan B. Yet, he added, that its prospects could be receding. Danon said Abbas is always welcome to directly negotiate with Israeli Prime Minister Benjamin Netanyahu but chooses not to.
"I think there is little appetite for other countries to step forward in the way the Palestinians envision", said Rumley.
"You are part of the problem, not the solution", Danon said, addressing Abbas. It called the speech "old talking points and undeveloped concepts for each of the core issues". The move led the Palestinian leadership to reject the role of the United States as an honest broker in negotiations with Israel. "But here we go again", Haley said.
The White House later issued a statement saying the administration was still working on its plan, "which is created to benefit both the Israeli and Palestinian people".
