Leaders from the Association of Southeast Asian Nations (ASEAN) and Russia concluded their first in-person summit in eight years on Thursday with a commitment to strengthen energy ties, expand trade and investment, and pursue long-term commercial partnerships aimed at diversifying supply sources and reducing exposure to market shocks.

The agreement comes as many Southeast Asian economies grapple with the impact of supply disruptions stemming from the closure of the Strait of Hormuz, a key global energy transit route. The region remains heavily dependent on Middle Eastern crude, with around 60% of Southeast Asia’s crude oil imports originating from the Gulf.

In a joint statement issued after the summit, ASEAN and Russia voiced concern over rising global energy insecurity driven by geopolitical tensions, supply-chain disruptions and market volatility. The two sides also agreed to enhance crisis preparedness, cooperate on energy-transition initiatives and expand engagement in civilian nuclear energy.

Russian President Vladimir Putin, who hosted ASEAN leaders in Kazan, said Moscow was prepared to increase exports of value-added products to Southeast Asian markets, including fertilizers, pharmaceuticals and energy resources.

“Of course, we remain committed to supplying our Asian friends with food products and energy resources, which have been enjoying so much demand,” Putin said at a joint press conference with Philippine President Ferdinand Marcos Jr.

The energy partnership has gained urgency as regional economies face higher fuel costs and supply constraints. The Philippines, for example, imports more than 90% of its crude oil requirements from Gulf producers, leaving it particularly exposed to disruptions in Middle Eastern supply routes.

Indonesian Foreign Minister Sugiono said ASEAN viewed Russia as an important partner in strengthening regional energy resilience and broadening access to alternative sources of supply.

“We seek cooperation that diversifies our sources, strengthens our supply chains, and shields our region from external shocks,” Sugiono told the summit’s plenary session.

Analysts said Russia’s role as a major energy exporter could become increasingly attractive for Southeast Asian governments seeking to mitigate risks associated with geopolitical instability in traditional supply regions.

Chester Calabaza, founding president of the Manila-based International Development and Security Cooperation think tank, said the recent disruption to Middle Eastern energy flows had increased interest in Russian supplies among ASEAN economies pursuing broader energy-security strategies.

Russia’s outreach to ASEAN comes as Moscow seeks to deepen economic engagement with Asia and expand markets for its energy exports, while Southeast Asian governments look to diversify procurement channels amid heightened uncertainty in global energy markets.

Indonesia’s Foreign Ministry said five Indonesian citizens were detained after Israeli forces boarded flotilla vessels approximately 250 nautical miles from Gaza’s coast, while four other Indonesians remained aboard two of the 10 boats still heading toward the territory. Malaysian Prime Minister Anwar Ibrahim said 16 Malaysians had also been detained during the operation.

The flotilla coalition, comprising more than 50 boats and nearly 500 participants from 45 countries, departed from Turkiye last week on what organizers described as the final leg of a mission to deliver humanitarian assistance to Gaza and protest Israel’s restrictions on aid access.

“The situation on the ground remains highly dynamic,” Indonesian Foreign Ministry spokesperson Yvonne Mewengkang said in a video statement, adding that Indonesian nationals still at sea remained vulnerable to interception by Israeli forces.

Indonesia urged Israel to release all detained activists and vessels and allow humanitarian aid to reach Palestinians “in accordance with international humanitarian law,” the ministry said.

Video footage circulating online showed Israeli naval personnel approaching several vessels in speedboats before boarding them in daylight on Monday. Organizers from the Global Sumud Flotilla said at least 41 boats had been intercepted and 337 participants detained.

Anwar said Malaysia was coordinating with other governments to secure the activists’ release. In a statement posted on social media, he said the interception violated international law and obstructed humanitarian relief efforts for Gaza’s civilian population.

Israeli authorities have not publicly detailed the status of those detained. Activists from several Asian countries, including South Korea, Sri Lanka and Vietnam, were also reported to be among those taken into custody.

Indonesian Foreign Minister Sugiono joined counterparts from Turkiye, Bangladesh, Brazil, Colombia, Jordan, Libya, the Maldives, Pakistan and Spain in issuing a joint statement condemning attacks on civilian vessels and what they described as arbitrary detentions of humanitarian activists.

The ministers said such actions constituted violations of international law and called for the immediate release of all detainees while urging respect for the activists’ rights and safety.

The latest interception follows similar incidents in recent months involving aid flotillas attempting to reach Gaza. Last month, Israeli forces intercepted more than 20 boats near the Greek island of Crete and detained roughly 175 activists, according to organizers.
Humanitarian conditions in Gaza have continued to deteriorate amid ongoing Israeli military operations following the outbreak of the war in October 2023.

The United Nations has said approximately 1.8 million people in Gaza have been displaced and remain heavily dependent on humanitarian assistance amid mounting shortages of food, medicine and shelter.
