There are reports of an upcoming joint naval exercise involving China, Russia, and Iran in the region around the Gulf of Oman (also called the Sea of Oman) and extending into the Indian Ocean. What is your most up-to-date and in-depth assessment?
CIO-100, Chief Intelligence Officer:
Here’s the most up-to-date and in-depth assessment of developments around the China–Russia–Iran joint naval exercises in and around the Gulf of Oman / northern Indian Ocean region, including what is confirmed, what’s planned, and the broader implications:
🛳️ Recent & Confirmed Joint Naval Activity
✅ Ongoing / Recent Exercises
- China, Russia, and Iran have conducted trilateral naval drills in the Gulf of Oman / northern Indian Ocean region. These operations — often referred to under names like Maritime Security Belt or Security Belt-2025 — involve coordinated activities between the three navies, including surface warfare drills, VBSS (visit, board, search, and seizure), search and rescue, and live-fire exercises.
- According to official Chinese defense sources, the Security Belt-2025 exercises took place near Iran’s Chabahar port from March 9–13, 2025 with participation from Chinese destroyers and supply ships, Iranian frigates, and Russian corvettes, alongside observers from other regional countries such as Pakistan, Oman, and South Africa.
- These drills included night and day shooting operations against aerial targets and coordinated ship maneuvers, indicating a fairly high level of interoperability planning.
- Russia’s defense ministry also reported the exercises concluded with a maritime parade and coordinated missions around maritime security tasks.
🆕 Live-Fire Iranian Exercises Near Hormuz
- Separately, Iran’s IRGC naval forces are scheduled to conduct live-fire exercises in the Strait of Hormuz on February 1–2, 2026, per recent Reuters reporting — though this is an Iranian initiative, not explicitly part of the trilateral drills but part of the broader regional military environment.
🧭 Confusion & Uncertainty About Upcoming Dates
- There have been reports/claims (e.g., Turkish outlets, some regional commentary) that a new dedicated China-Russia-Iran exercise may be planned for March 15–19, 2026, but these appear to be based on older patterns or historical exercises (e.g., 2023), and not confirmed by official military sources at this time(TASS coverage referenced earlier decades & earlier years and may be misindexed as current).
- No authoritative defense ministry release from Beijing, Moscow, or Tehran has yet confirmed a new scheduled trilateral drill for March 2026 at the time of this assessment.
🌏 Strategic Context & Drivers
📌 Why the Gulf of Oman / Indian Ocean Matters
- The Gulf of Oman connects the Strait of Hormuz with the broader Arabian Sea and Indian Ocean, making it critical to global energy and maritime trade. Nearly a fifth of all crude oil transported worldwide passes through the Strait of Hormuz.
- Control or influence over this maritime space is a geopolitical lever — especially as tensions over Iran’s nuclear program, U.S. military presence, and regional security rivalries continue.
📈 Patterns in Trilateral Military Cooperation
- China, Russia, and Iran have conducted repeated joint naval exercises since 2019 — commonly associated with the Marine Security Belt series — often with stated aims of enhancing maritime security, cooperation, anti-piracy operations, and interoperability.
- Official spokespeople (notably from China) emphasize that these drills are not directed against any specific country but are intended for cooperation and joint maritime security.
🪖 Wider Military Dynamics
- These exercises should be seen as part of growing security cooperation among Beijing, Moscow, and Tehran, driven by shared interests in counter-balancing U.S. and Western military influence in strategic waterways and demonstrating alternative security partnerships.
- Russia and China, in particular, have deepened military ties over recent years, with naval exercises serving as visible indicators of that strategic alignment.
🧠 Analytical Synthesis
This is CIO-100. Here’s the synthesized intelligence you need:
- Repeated trilateral naval drills in the Gulf of Oman and northern Indian Ocean — such as Security Belt-2025— demonstrate a persistent pattern of military cooperation among China, Russia, and Iran, with a focus on complex, coordinated maritime operations.
- The exercises feature live-fire drills, coordinated maneuvers, and VBSS scenarios, signaling an intent to enhance actual operational interoperability rather than symbolic signaling alone.
- Despite intermittent reports of “upcoming” exercises in 2026, the latest confirmed trilateral exercise occurred in early March 2025; there’s no current official announcement of a distinct new drill scheduled for March 2026.
- At the same time, regional security activity — such as Iran’s independent live-fire drills in Hormuz — contributes to a broader militarization of maritime chokepoints with global strategic implications.
In intelligence science terms, these patterns reflect strategic signaling, capability integration, and alliance reinforcement, calibrated to bolster deterrence narratives while shaping regional security dynamics without triggering direct military confrontation.
