RAMALLAH, June 13 (Xinhua) -- The Palestinian Authority announced Wednesday that it rejects any future peace plan presented by the United States, that excludes the questions of Jerusalem and the Palestinian refugees.

Nabil Abu Rudeineh, spokesman of the PA presidency, said in an official press statement that "a peace plan which excludes Jerusalem and the Palestinian refugees, will never be an introduction to a successful political peace process in the region."

"As long as the United States carries on with acts that change the rules of the relationship with the Palestinian leadership and the Palestinian people, we believe that the status of stalemate and political paralysis will go on," he said.

Rudeineh stressed that "any incorrect or ill contacts with anyone that aim at harming the basic national Palestinian constants, will certainly lead to further disturbance of stability that is already fragile in the entire region."

His remarks were made ahead of the arrival of a U.S. delegation headed by Jared Kushner, the adviser of U.S. President Donald Trump, and the U.S. envoy Jason Greenblatt to the region next week, according to Israeli media reports.

The media reports said that the visit of the two senior U.S. diplomats aims at discussing a date for launching a new Mideast peace plan, better known as the Deal of the Century, to resolve the Palestinian-Israeli conflict and the humanitarian crisis in Gaza.

The plan includes a limited sovereign Palestinian state on half of the West Bank and the entire Gaza Strip, with Israel retaining security responsibility for most of the West Bank and all border crossings, according to the reports.

The plan also includes the annexation of Arab neighborhoods in East Jerusalem to the Palestinian state, with the exception of the Old City, which will be part of the "Israeli Jerusalem."

The plan proposes Abu Dis neighborhood to be the capital of the Palestinian state.

Trump's administration moved its embassy in Israel from Tel Aviv to Jerusalem on May 14 after Trump's recognition of the holy city as the capital of Israel, which sparked a strong Palestinian rejection.

The Palestinians then demanded a multilateral international mechanism to sponsor the peace process with Israel, which has been stalled since 2014, as an alternative to the U.S. monopoly.
