We'll have it solved: Trump on mediation in Qatar crisis

United States President Donald Trump has hailed the efforts made by the leaders of Kuwait to mediate in solving the crisis of Qatar and its Arab neighbours, however, Trump said a deal would be "worked out very quickly," if he became personally involved.

"Kuwait has been really the leader of getting it solved, and we appreciate that very much. But I do believe that we'll solve it. If we don't solve it, I will be a mediator right here in the White House. We'll come together. Very quickly, I think, we'll have something solved," Trump said, at a White House news conference.

"While I do appreciate and respect the mediation, I would be willing to be the mediator. I was telling the Emir before that if I can help between the U.A.E. and Saudi Arabia," he added.

Trump said all members of the Gulf Cooperation Council are "essential partners" with the U.S. in efforts to crack down on extremism, including the fight against Islamic State group.

"We will be most successful with a united GCC," he said.

"We will send a strong message to both terrorist organisations and regional aggressors that they cannot win."

Earlier, Trump welcomed the Emir of Kuwait, Sabah Al-Ahmad Al-Jaber Al-Sabah on Twitter.

"Welcome to the @WhiteHouse, Amir Sabah al-Ahmed al-Jaber al-Sabah of Kuwait! Joint press conference coming up soon," he tweeted.

The crisis erupted on June 5 when Bahrain, Egypt, Saudi Arabia and the United Arab Emirates cut ties with Doha over allegations of Qatar funding extremists and having warm ties with Iran too.

Qatar, which hosts a U.S. military base critical to the effort to defeat the Islamic State in Iraq and Syria, has long denied funding extremists.
