JAKARTA – Singapore and Indonesia have pledged to keep the Strait of Malacca open, safe and accessible to all, elevating maritime security to the forefront of a bilateral relationship that both countries increasingly see as critical to regional stability and economic growth.
The commitment emerged after talks on July 6 between Prime Minister Lawrence Wong and President Prabowo Subianto at the annual Leaders’ Retreat, where they stressed the importance of safeguarding one of the world’s busiest shipping routes amid growing geopolitical uncertainty.
Reaffirming the two countries’ “special” and “unique” relationship, the leaders held discussions that highlighted how the relationship is evolving beyond trade and investment into new areas such as renewable energy, cross-border electricity trade, digital infrastructure and supply chain resilience.
“The Leaders’ Retreat is a unique feature of the Singapore-Indonesia relationship. It reflects the special relationship between our two countries, one that is characterised by close ties, as well as mutual trust, respect and understanding,” said PM Wong at a joint press conference with President Prabowo.
In the same vein, President Prabowo underscored how both countries share a responsibility to safeguard regional security and economic growth. “Prosperity will never come without peace and stability,” he said.
The Strait of Malacca, which connects the Indian Ocean and the South China Sea, carries a significant share of global trade and energy shipments, making it one of the world’s most strategically important maritime corridors.
President Prabowo said Indonesia and Singapore had reaffirmed their shared position on the waterway.
“Indonesia and Singapore are countries that directly border one another in the Strait of Malacca. We have a shared interest in maintaining the Strait of Malacca as a passage that is free for all parties,” he said.
“We must preserve security and peace in the strait, and also, of course, protect it from pollution, accidents, and from robbery or piracy.”
He added that Indonesia would continue coordinating with Malaysia and Thailand to ensure that, in accordance with the United Nations Convention on the Law of the Sea (UNCLOS), the strait would “always remain open to all, safe and accessible to anyone who requires access”.
PM Wong struck a similar note, linking maritime security to wider global developments.
He said recent events in the Middle East had highlighted the importance of keeping major trade routes functioning and secure. The Iran war had choked off traffic in the Strait of Hormuz, leading to disruptions in global trade and the supply of oil.
“As littoral states bordering the Strait of Malacca and Singapore, both Singapore and Indonesia are strategically aligned,” he said.
“We both share interest in upholding navigational rights and freedoms, and keeping sea lines of communication open to all, including the unimpeded rights of transit passage of vessels, in accordance with UNCLOS which is also customary international law.”
The two leaders agreed to work with other littoral states to ensure that the Strait of Malacca and Singapore remain safe, open and accessible.
President Prabowo said Singapore and Indonesia shared common interests as neighbours in the same region, adding that peace and stability required constant effort and cooperation.
“Stability and peace are not something that will come by themselves,” he said. “We must carry it out without rest.”
The leaders also exchanged views on regional and global developments. President Prabowo said they had reaffirmed ASEAN’s longstanding position that disputes should be resolved peacefully through dialogue and diplomacy, a principle he said should apply “not only in our region, but in all regions”.
New growth areas
While maritime security featured prominently at the retreat, much of it also focused on expanding cooperation into new sectors expected to shape both economies in the years ahead.
Among the most significant developments was progress on cross-border electricity trade, which both countries see as a cornerstone of future energy cooperation.
Indonesia announced that sovereign investment fund Danantara would take the lead in implementing cooperation on cross-border electricity trade, as well as future collaboration in trade, energy and the digital economy.
Singapore and Indonesia also signed new agreements involving Danantara and Singapore firms Keppel Electric, Sembcorp Industries and Singapore Energy Interconnections, which are aimed at advancing discussions on future electricity exports.
PM Wong said the arrangements would provide a road map for negotiations and pave the way for a cross-border electricity project between the two countries.
He described the initiative as a “win-win” project and an important building block for a wider ASEAN Power Grid that could strengthen regional energy security.
PM Wong also highlighted a planned solar project in Morowali in central Sulawesi, where Singapore and Indonesia are collaborating to develop renewable energy. The area is one of Indonesia’s largest nickel processing centres, where energy-intensive industries have driven growing demand for electricity.
“This will unlock the clean supply of electricity to power industries there,” he said.
The two sides also highlighted cooperation in supply chains, cybersecurity and digital infrastructure.
President Prabowo said discussions on the digital ecosystem and cybersecurity had produced “fairly concrete outcomes”, while both leaders agreed to continue strengthening supply chain resilience and economic connectivity.
PM Wong said the two sides also agreed to strengthen institutional links, adding that in particular, good relations between the Singapore Armed Forces and Tentara Nasional Indonesia, Indonesia’s national armed forces, foster trust between the two countries.
Vote of confidence in Indonesia
The retreat also served as a strong endorsement of Indonesia’s economic prospects.
PM Wong repeatedly stressed Singapore’s confidence in Indonesia’s future and signalled that Singapore intends to remain a long-term partner in the country’s development.
“Singapore has every confidence in Indonesia’s future,” he said. “We want Indonesia to succeed because our futures are closely linked.”
He said Singapore’s investments in Indonesia went beyond capital flows and were helping to create businesses, downstream industries, digital infrastructure and jobs.
Singapore companies continue to see opportunities across Indonesia, he added, pointing to developments in the Batam, Bintan and Karimun region as well as the Kendal Industrial Park in central Java.
The industrial park, which marks its 10th anniversary in 2026, has reached full capacity and is set to expand by another 1,000ha.
PM Wong said the expansion would attract further investment, create jobs and support Indonesia’s growth.
For his part, President Prabowo emphasised the strength and maturity of the bilateral relationship, saying the two leaders had held “intensive and highly productive discussions” which were “heart to heart” and “forward-looking”.
He said both sides had agreed that any misunderstandings or differences would be addressed candidly.
“We agreed that if there are misunderstandings or misperceptions, we will resolve them as friends, openly,” he said.
President Prabowo said the relationship rested not only on cooperation between governments but also on strong ties between ordinary Indonesians and Singaporeans.
“A strong partnership is built on the basis of trust, not only between governments but also between the peoples of both countries,” he said.
The talks reflect a broader effort by both countries to link their economic and strategic interests more closely as they prepare to mark 60 years of diplomatic relations in 2027.
In a statement, Singapore’s Ministry of Foreign Affairs said the two leaders agreed to work closely during Singapore’s ASEAN chairmanship in 2027 and looked forward to commemorating 60 years of diplomatic relations that year.
Reflecting on the strength of bilateral ties, both PM Wong and President Prabowo emphasised the close and enduring partnership between Singapore and Indonesia.
The retreat on July 6 shows just how close both sides are, President Prabowo said. “I emphasise here that today’s Leaders’ Retreat demonstrates the maturity, trust and strategic value of the Indonesia-Singapore relationship,” he added.
PM Wong said Singapore and Indonesia are trusted partners with a shared stake in each other’s success, describing the relationship as deep, forward-looking and full of potential.
He added: “Together, we can create more opportunities than either of us could achieve alone.”
