Jared Kushner, son-in-law and senior adviser to US President Donald Trump, met in Cairo Thursday with President Abdel Fattah al-Sisi to discuss the US administrations Middle East peace plan.

Accompanied by Jason Greenblatt, President Trump’s envoy for the Middle East, Kushner briefed the Egyptian president about their progress in reaching out to various Mideast various parties, in order to ”put negotiations between Palestinians and Israelis back on track”.

According to the Egyptian president, the two sides discussed “ways to consolidate peace and stability in the region”, and reiterated that is committed to a two-state solution. But he made it very clear to the US envoy that he won’t allow Sinai to be included in the peace deal.

Kushner is touring several states in the region to promote the controversial Washington peace plan, that has preemptively been rejected by the Palestinians and criticized by Jordan. On Wednesday, he met King Abdullah II of Jordan in Amman and met in Israel with Prime Minister Benyamin Netanyahu.

Kushner presented the economic component of the US plan in Bahrain back in June. He proposed raising $50 billion to invest in the economic rehabilitation of the Palestinian territories and neighboring Arab countries over a ten-year period.

The political part of the plan, which is where the contention lies has still not been publically unveiled by the Trump administration.

The PA has boycotted the US peace plan, accusing the Trump administration of bias towards Israel.
