Cairo (AFP) - Saudi King Salman on Thursday started a five-day visit to Cairo in a show of support for Egyptian President Abdel Fattah al-Sisi, with the leaders due to sign a raft of investment deals.
Saudi Arabia has been the key backer of Sisi since the then-army chief in 2013 overthrew his Islamist predecessor Mohamed Morsi, whose Muslim Brotherhood movement was viewed with suspicion by Riyadh.
It has pumped billions of dollars in aid and investment into Egypt's battered economy, and the two heads of state are expected to ink more investment agreements on Friday amounting to about $1.7 billion.
Live footage on state television showed Sisi greeting the 80-year-old Salman at Cairo airport, before heading off in a convoy to the presidential palace.
The two met after Salman's arrival and were due to meet again on Friday, when they will sign 14 agreements that include a $1.5 billion deal to invest in the Sinai Peninsula, the presidency and an Egyptian government official said.
Salman is expected to address the Egyptian parliament on Sunday, state media reported.
Egyptian media gave full coverage of the visit, with state television welcoming Salman to his "second country" and playing celebratory music as his plane touched down in Cairo.
"This is the first official visit by King Salman, whose valuable and honourable positions in support of Egypt and its people will never be forgotten," the presidency said in a statement before Salman's arrival.
After he met Sisi, the presidency said the leaders sought "a qualitative transformation in the brotherly and historical bonds that tie the two nations".
The visit follows months of reports in both Saudi and Egyptian newspapers of strained ties over Cairo's unwillingness to participate fully in the Saudi-led war against Iran-backed Shiite rebels in Yemen.
Egypt had announced it would back Saudi Arabia with ground troops if needed, but appears to have balked at the prospect of becoming mired in the conflict.
Sisi's close relationship with Russian President Vladimir Putin, who militarily backs Syrian leader Bashar al-Assad against Saudi-supported rebels, has reportedly also caused friction with Riyadh.
However, Saudi Arabia has played a key role in propping up Egypt's economy, whose vital tourism industry has been devastated by years of political turmoil and jihadist attacks.
For Saudi Arabia, which is in competition with regional rival Iran, keeping Egypt under its aegis is crucial.
