In a significant display of regional cooperation, Singapore and Indonesia have reaffirmed their commitment to maintaining the Strait of Malacca and the Singapore Strait as open and unimpeded waterways for international shipping. This joint declaration underscores the strategic alignment between the two nations in safeguarding these vital maritime corridors, which are crucial for global trade and energy transportation.
The reaffirmation took place during the second Singapore-Indonesia Leaders’ Retreat held in Jakarta on July 6, 2026. Singapore's Prime Minister Lawrence Wong and Indonesian President Prabowo Subianto addressed the importance of upholding navigational rights and freedoms in the region. Both leaders emphasized their shared interest in ensuring the safety, openness, and accessibility of these waterways to all vessels, in accordance with international law.
The Strait of Malacca and the Singapore Strait are among the world's busiest maritime routes, facilitating the passage of a significant portion of global trade and energy supplies. Their strategic importance has been highlighted in recent times, especially in light of global geopolitical developments that have raised concerns about the security and freedom of international shipping lanes.
During the retreat, Prime Minister Wong articulated Singapore's position, stating, "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 (United Nations Convention on the Law of the Sea), which is also customary international law." This statement reflects Singapore's steadfast commitment to the principles enshrined in UNCLOS, which guarantees the right of transit passage through straits used for international navigation.
President Prabowo echoed this sentiment, highlighting the longstanding cooperation between Singapore and Indonesia in managing the Strait of Malacca. He emphasized the importance of preserving peace and security in the strait, while also protecting it from pollution, accidents, and piracy. "We must preserve peace and security in the strait, while also protecting it from pollution, accidents and piracy," he said, adding that both nations would continue coordinating closely with Malaysia and Thailand on this shared interest.
The leaders also addressed the broader regional context, discussing developments in the Middle East and their potential implications for global shipping routes. They agreed on the importance of ASEAN and ASEAN centrality in addressing such challenges, reaffirming their commitment to resolving disputes peacefully through dialogue and diplomacy. This approach aligns with ASEAN's longstanding position on conflict resolution and regional cooperation.
The commitment to keeping the Strait of Malacca and the Singapore Strait open and free is not a new stance for Singapore and Indonesia. Both countries have a history of collaborative efforts to ensure the safety and security of these maritime passages. In April 2026, Singapore's Foreign Affairs Minister Vivian Balakrishnan highlighted the shared strategic interest among Singapore, Malaysia, and Indonesia in keeping the straits open. He noted that all three nations are trade-dependent economies and have a cooperative mechanism to avoid imposing tolls, emphasizing the importance of maintaining free passage through these waterways.
The recent reaffirmation by Singapore and Indonesia serves as a timely reminder of the critical importance of the Strait of Malacca and the Singapore Strait in global trade and energy supply chains. The collaborative efforts between these two nations, along with their ASEAN partners, are vital in ensuring that these maritime corridors remain open, safe, and free from disruptions. As global trade dynamics continue to evolve, the commitment of Singapore and Indonesia to uphold the principles of freedom of navigation and international law remains a cornerstone of regional stability and prosperity.
In conclusion, the joint declaration by Singapore and Indonesia to keep the Strait of Malacca and the Singapore Strait open and free underscores the strategic alignment between the two nations in safeguarding these vital maritime routes. Their commitment to upholding international law and ensuring the safety and security of these waterways is a positive development for regional and global trade, reinforcing the importance of cooperative efforts in managing shared maritime resources.
