Saudi Arabia and Syria sign a defence pact as Houthi attacks continue
The Saudi and Syrian defence ministries signed a cooperation agreement in Riyadh on 4 November; its terms were not disclosed. The Saudi Fund for Development granted Syria 6 concessional loans totalling more than 403 million dollars. Damascus is considering joining the three-country Mecca alliance formed by Saudi Arabia, Türkiye and Pakistan.
According to a Reuters report carried by TBS News, the agreement was signed on 4 November in the presence of Crown Prince Mohammed bin Salman and President Ahmed al-Sharaa. It was Sharaa's second visit to Riyadh in under 30 days. Syria's foreign ministry called the agreement the most important of more than 6 documents signed that day, but did not disclose its terms.
The loan breakdown comprises 100 million dollars for health, 60 million for housing, 105 million for civil defence, 90 million for the Aleppo thermal power plant and 30 million for drinking water. These items add up to 385 million dollars; the roughly 18 million dollars between that and the 403-million-dollar total does not appear in the breakdown. Syrian Foreign Minister Asaad al-Shaibani said at the Manama Dialogue on 31 October that joining the Mecca alliance had been discussed.
According to a Reuters report published by Internazionale, the Houthis claimed to have attacked the city's international airport on 4 November while Sharaa was in Riyadh; Saudi authorities did not confirm this. According to Reuters, Damascus is one of at least 4 countries from which Riyadh has sought support. Egypt agreed in October to provide military support to the kingdom and Britain pledged defensive sorties; Reuters wrote on 5 November that Türkiye was preparing to ratify the three-country pact.
Talay assessment
Bottom line
Riyadh is resting its defence against Houthi attacks not on a single ally but on a network stretching from Egypt to Syria. With the agreement's terms undisclosed, what Syria will bring on the ground is unclear; the 403-million-dollar loan package shows that, for now, the economic leg of the relationship is the more concrete one.
Likely effects
- Regional alliancesUncertain1–6 months
Syria joining the Mecca alliance would extend the defence framework formed by Saudi Arabia, Türkiye and Pakistan into the Levant.
- TürkiyeUncertain1–6 months
Türkiye's ratification of the three-country pact and Syria's accession talks bring Ankara closer to the centre of the Saudi defence network.
- Syrian infrastructurePositive6 months+
The 90 million dollars earmarked for the Aleppo thermal power plant could partly reduce Syria's electricity shortfall.
