Vietnam and Singapore Deepen Military Ties as China Conducts New South China Sea Exercises
Vietnam has deepened its military relationship with Singapore through a new exercises-of-forces agreement signed in Hanoi, as the two countries sought to demonstrate unity in maintaining freedom of navigation in the South China Sea amid rising regional tensions. The agreement, signed during Singapore Defense Minister Ng Eng Hen’s visit to the Vietnamese capital, represents the most significant expansion of bilateral defense ties between the two countries in more than a decade, and signals a shared concern about the accelerating assertiveness of Chinese maritime claims across the region.
Singapore and Vietnam Sign Expanded Military Exercises Pact
Vietnam and Singapore signed a new exercises-of-forces pact expanding their existing bilateral defense relationship into a broader framework for joint training, intelligence sharing, and port call privileges. Under the agreement, Singapore will host Vietnamese naval vessels at its Changi Naval Base for the first time, while Vietnamese air force personnel will participate in joint fighter exercises over the South China Sea beginning next quarter. The pact also establishes a new channel for regular defense policy consultations at the deputy minister level, giving both sides a structured forum to discuss regional security developments.
The agreement comes as China intensifies its claims over disputed maritime territories in the South China Sea, following a series of incidents involving Philippine and Vietnamese fishing vessels near the Spratly Islands. China’s coast guard has increasingly used water cannons and laser weapons against vessels it regards as operating in waters it claims, incidents that have drawn condemnation from the United States and prompted several ASEAN members to seek stronger bilateral defense ties. “This partnership is not directed at any third country,” Singapore’s Ministry of Defense said in a statement. “It reflects our shared commitment to regional stability and the rules-based international order.”
Australia separately announced it would expand its defense cooperation with the Philippines through a new coast guard training program based in Manila. Defense Minister Richard Marles said the program would help the Philippines monitor its exclusive economic zone more effectively, including in areas near the Spratly Islands where Chinese maritime activity has increased sharply. The announcement followed a visit by Marles to Manila last week, during which he met with his Philippine counterpart to discuss expanding the two countries’ 1951 Status of Forces Agreement to include more extensive joint training provisions. Australia and the Philippines have been steadily deepening their security relationship over the past three years, driven largely by shared concerns about Chinese pressure on Philippine vessels in the South China Sea.
China Conducts New South China Sea Exercises Amid Regional Pushback
China’s People’s Liberation Army Navy conducted new exercises in the South China Sea deploying a destroyer squadron and two frigates to an area south of the Paracel Islands. The exercises included live-fire drills and anti-submarine operations, according to a statement from China’s Southern Theater Command. The drills come after the Philippines reported that Chinese coast guard vessels had used water cannons against Filipino fishing boats near Scarborough Shoal, and after Vietnam accused Chinese maritime patrol boats of deliberately cutting the cables of a Vietnamese research vessel operating in its own exclusive economic zone. The incidents have stoked concerns across the region about Beijing’s willingness to use coercive measures to enforce its sweeping maritime claims.
Japan’s Maritime Self-Defense Force said it was closely monitoring the PLA Navy exercises and stood ready to dispatch vessels if the exercises approached waters near Japan’s southern islands. “The situation in the South China Sea is directly relevant to Japan’s security, and we have a stake in ensuring freedom of navigation and overflight in the region,” a Japanese Defense Ministry spokesperson said. “We will not hesitate to take necessary actions to protect our national interests.” Japan’s own coast guard has increased its patrols near the Senkaku Islands in the East China Sea, where Chinese maritime activity has also risen sharply over the past year, according to data from Japan’s Ministry of Defense.
The new security architecture taking shape across the Indo-Pacific is increasingly organized around overlapping bilateral and multilateral agreements rather than a single dominant alliance structure. “What we are seeing is a lattice of security relationships that are deepening and interlocking,” said a senior ASEAN official, speaking on condition of anonymity. “No single country is driving it. It is being driven by shared concerns about regional stability and by the actions of one country that is trying to change the status quo by force.” The official declined to name the country, but the description matched China’s behavior in both the South China Sea and the Taiwan Strait, where PLA exercises have grown more frequent and more complex over the past 18 months.
