• The U.S. maintains close ties with both Qatar and its rivals, but the Trump administration's past several attempts to reconcile the parties have been unsuccessful. 
• Both Gulf countries see the signing of the agreement as a gesture to the Trump administration and part of their effort to “clean the table” to prepare for the incoming Biden administration.
• Jared Kushner mediated between the parties and traveled to Saudi Arabia to participate in the signing during this week's Gulf Cooperation Council (GCC) summit. 

Ahead of the signing of the agreement, the Kuwaiti foreign minister announced that Saudi Arabia and Qatar would open their land, air and sea borders starting on Monday night.

Kushner traveled to the GCC summit in Al Ula, Saudi Arabia, with White House envoy Avi Berkowitz and adviser Brian Hook, who helped negotiate the agreement.

• The summit will be the first time the Emir of Qatar Tamim Bin Hamad al-Thani will visit Saudi Arabia since the crisis erupted in 2017. The leaders of Saudi Arabia, Bahrain, the United Arab Emirates, Oman and Kuwait will also attend.
• The leaders are going to sign an agreement that includes three confidence-building measures: Saudi Arabia, UAE and Bahrain will lift the air and sea blockade of Qatar; Qatar will withdraw all lawsuits against its three Gulf neighbors; and all parties will stop their media campaigns against each other.

The deal was reached in principle during Kushner’s last visit to Saudi Arabia and Qatar several weeks ago, where he met Saudi Crown Prince Mohammed bin Salman and Sheikh Tamim. Kushner has close relationships with both leaders.

• U.S. officials say that after meeting the Saudi crown prince, Kushner traveled to Qatar's capital Doha with Hook while leaving close aides Berkowitz and Adam Boehler behind in Saudi Arabia. The two mediated talks between the Saudis and the Qataris over the phone in real time until a draft deal was reached.
• In the last few weeks, final discussions were held with the Saudis and the Qataris to ensure both sides were committed to the understandings that were reached, the officials told me.
• The White House also lobbied the UAE, Bahrain and Egypt — all three of which have reservations about the agreement, as they view Qatar in a negative light and do not believe the Qataris are sincere.
• The deal almost fell apart on Sunday when a last-minute miscommunication created new tensions between the Saudis and the Qataris, sources briefed on the matter told me.
• Kushner and his team were supposed to leave on Sunday afternoon but postponed their trip. A source told me Kushner and his team were forced to negotiate with the Saudis and the Qataris into the night on Sunday until a solution was found. They left Washington en route to Saudi Arabia early Monday morning.

A senior diplomat from one of the Gulf countries told me the agreement is a step in the right direction and includes some positive developments — but it does not mark the end of the Gulf rift.

• “Some of the issues were solved, but the root causes for the rift — bad personal relationships between the leaders and big policy differences on Iran, Turkey and the Muslim Brotherhood — are still there," the diplomat told me.

The agreement, which will be signed on Tuesday, would be a last-minute achievement for Kushner and the Trump administration before President-elect Joe Biden takes office on Jan. 20.
