Egypt's President Abdel Fattah El-Sisi met with President Donald Trump in Riyadh on Sunday morning, according to Al-Arabiya news channel.

Trump said in the meeting that he would visit Egypt, adding the nation to his schedule soon.

"I will get to Egypt. We will absolutely be putting that on the list very soon, Sisi had "done a tremendous job under trying circumstance", said Trump, who is on his first foreign visit since taking office.

"We've really been through a lot together positively", Trump said on his talks with Egypt' Sisi.

The U.S President also affirmed he was having "very, very important talks" with his Egyptian counterpart.

The US president also thanked El-Sisi for his help with the release of Egyptian-American charity worker Aya Hijazi last month, according to Reuters.

For his part, El-Sisi described Trump as a "unique" personality that is capable of doing the impossible.

Trump and El-Sisi met in Washington in April, with the US president vowing to provide Egypt with support in its battle against terrorism.

Sunday saw the two men meeting ahead of two multilateral summits to be in Riyadh: the Arab Islamic American Summit (AIAS) and the Gulf Cooperation Council and United States Summit.

Both events are scheduled for Sunday and will be attended by Trump and Saudi King Salman bin Abdulaziz al-Saud.

El-Sisi arrived in the Saudi capital on Saturday on a two-day visit for high-level talks on regional and international issues, with regional security among the main topics for discussion.

Trump's arrival on Saturday marked his first foreign visit, as he embarked on a tour of the Middle East and Europe. He is also scheduled to travel to Israel and the Vatican.

El-Sisi is set to deliver a speech on Sunday as part of the summit schedule, according to presidency spokesman Alaa Youssef.

"The president will address the Egyptian vision towards framing a comprehensive strategy to fight the danger of terrorism, through intensifying international efforts aimed at suspending financing for terrorist organisations, weapons and fighters, and [denying them] shelter," the spokesman added.

El-Sisi is also scheduled to hold bilateral meetings with a number of leaders and officials who will be participating in the summits, in order to reinforce relations and discuss potential opportunities for cooperation at various levels, said the spokesman.

The invitation to the summits follows an earlier meeting between El-Sisi and Salman in late April in the Saudi capital. The two Arab leaders said they looked forward to enhancing cooperation to face challenges and restore security and stability in the region, referring to the conflicts in Syria, Yemen and Libya.
