The development
Singapore MINDEF reported that RSS Steadfast and PLANS Dali participated in Exercise Maritime Cooperation at Zhanjiang on 5–9 September 2026. China’s defense ministry described the same exercise on 14 September, giving a 3–9 September period. Both describe activities ashore and at sea.

Opening note
Singapore’s MINDEF places Maritime Cooperation 2026 at Zhanjiang on the final leg of RSS Steadfast’s three-month deployment with several naval partners. China’s defense ministry describes the exercise through bilateral cooperation. MINDEF’s closing release uses that frame too: the wider deployment context and the shared message about trust sit alongside each other. [4466, 4472, 4164]
What stood out
MINDEF gives 5–9 September, with shore activity on 5–7 September and a sea phase on 8–9 September. China’s ministry gives 3–9 September. PLA Daily reports a 5 September opening and preparatory meetings on 4 September; its later feature describes a five-day exercise ending on 9 September. Preparation and the formal exercise may have been counted differently, but no cited record explains the ministry’s 3 September starting point. [4466, 4472, 4164, 3924, 4102]
Both ministries list communications, search and rescue, and casualty-related drills. MINDEF names gunnery firing; China’s ministry names live-fire shooting. The Chinese ministry also lists replenishment, which neither cited MINDEF release names. PLA Daily describes replenishment positioning and line handling; it does not establish that fuel or stores were transferred. [4466, 4472, 4164, 4102]
Why it matters
For a policy reader, MINDEF’s opening release places cooperation with China among Steadfast’s engagements with several partners. Its closing release emphasizes the bilateral relationship, much as China’s ministry does. Reading the closing statements alone would miss the deployment context. Reading the opening statements as opposing political messages would overstate the contrast: a deployment-wide release and an answer about one exercise have different scopes. [4466, 4472, 4164]
MINDEF’s closing release cites improved operational competencies; China’s ministry claims an increased ability to maintain regional peace and stability. These are participant assessments. The five records provide no independent performance measures against which to test them. [4472, 4164]
Routine baseline
MINDEF dates the series to 2015, and both ministries call this its fifth iteration. That supports an assessment of continuity. Without a comparable earlier program or scale, this brief makes no finding about expansion or improved combat effectiveness. [4466, 4472, 4164]
Term to know
What I'm watching next
An official explanation of the 3 September starting date would clarify the exercise’s broader timeline. More specific replenishment reporting could establish whether the work went beyond positioning and line handling. [4164, 3924, 4102]
A changed program or scale would become more meaningful alongside a documented earlier iteration. Comparable performance measures would help test the benefits the ministries assert. [4466, 4472, 4164]

Both ministries list communications, search and rescue, and casualty-related drills. MINDEF names gunnery firing; China’s ministry names live-fire shooting. China’s ministry also names replenishment, which the two MINDEF releases do not name. This establishes a difference in their published lists.

Both ministries call this the fifth iteration and associate it with cooperation and trust. This is an attributed assessment of an established exercise series; the records provide no comparative performance measures.

Compared side by side · China Desk and Singapore Desk
MINDEF’s opening release places the exercise within Steadfast’s deployment involving several partners. Its closing release and China’s ministry answer both emphasize bilateral trust and cooperation. The wider deployment context and bilateral message coexist in the Singapore account.
