Houthis advance along Yemen's Red Sea coast and target oil-rich Marib

Coastal offensive and energy chokepoints

Yemeni Houthi militants led by Abdulmalik al-Houthi have expanded control over the country's Red Sea coast and several offshore islands. The push tightens the group's position near the Bab al-Mandeb Strait, a maritime passage connecting the Red Sea to the Arabian Sea and European markets. In July 2026, the Houthis broke a 2022 truce with Saudi Arabia by declaring a blockade on Saudi ports and attacking tankers. Recent operations have included daily drone and missile strikes against Saudi energy infrastructure, contributing to global oil prices reaching their highest levels since mid-May 2026. Following drone attacks reported from Iraq on the East-West pipeline in the Riyadh and Medina regions, Saudi Aramco shut the pipeline as a precautionary measure.

Battle for the Marib oil reserves

Houthi forces have pushed eastward toward Marib governorate, located approximately 120 kilometers east of the capital, Sanaa. Marib holds some of Yemen's largest oil and natural gas fields, making the region a central financial asset for the internationally recognized government. Fighting has also intensified across the provinces of Taiz and Hajjah, reaching levels not seen since the previous offensive against Marib was repelled in 2021. If government defenses collapse, Houthi units would gain an overland route into Hadramaut, Yemen's largest province, and approach the Saudi border.

It is the bastion and stronghold in the north of those who resisted the militia coup over a decade ago. A capture would be a symbolic and strategic victory.

Saudi Arabia and Yemeni government forces have responded by stepping up airstrikes to stall the advance. Analysts pointed out that a Houthi victory in Marib would bring the militia directly to the Saudi border, creating immediate security concerns for Riyadh.

If Marib falls to the Houthis, the militia would be right at the Saudi-Yemeni border. That would be intolerable for Saudi Arabia and would endanger the country's national security.

Ascendance within the Iranian network

The territorial gains reflect a changing hierarchy among Iran-aligned groups in the region. After the United States and Israel launched strikes against Iran in late February 2026, the Houthis initially remained on the periphery before expanding operations. With Lebanon's Hezbollah weakened by recent Israeli military operations and the loss of its operational base in Syria, Iranian state media and public rallies have elevated Sanaa's role. The Institute for the Study of War reported that Houthi maritime control aims to establish an axis-controlled body of water alongside the contested Strait of Hormuz. In Tehran, hardline state newspapers praised the territorial advances, while crowds at state-organized rallies chanted slogans in support of Yemen.

Diplomatic appeals and Beijing's response

The disruption of shipping lanes prompted Saudi officials to seek foreign diplomatic assistance, including contacts with Washington and indirect engagement through China. According to three sources cited by Reuters, Chinese officials contacted Tehran behind the scenes at Saudi Arabia's request to urge restraint regarding Houthi operations. China relies heavily on Middle Eastern energy imports and serves as the primary buyer of Iranian crude, giving Beijing direct economic exposure to disruptions in both the Strait of Hormuz and the Bab al-Mandeb Strait. Iranian officials responded that stability in the waterways would return only after US and Israeli operations against Iran conclude.

China does not want regional tensions to spread further to Yemen and the Red Sea. Increasing regional instability is not in the interest of any party involved.
