China-Russia Joint Naval Exercises Prompt Asian Regional Response: Strategic Implications for the Indo-Pacific
Military cooperation between China and Russia is now an emerging factor in the security environment of the Indo-Pacific region. The regular exercises and patrolling missions conducted by them have begun to attract more attention from regional countries due to increasing activities of China at sea and efforts made by Russia to remain militarily present in the Asia-Pacific region.
The current events occur in the context of increasing security concerns in the region. In the Japanese defense white paper published in 2026, China was referred to as the “greatest strategic challenge” of Japan. Furthermore, China’s growing military cooperation with Russia is mentioned in the document.
Thus, what matters is not only the exercises conducted by them but also the question for other Asian countries whether these repeated joint missions are developing their operational synergy and altering the calculations of different countries in the Indo-Pacific region.
What Are China and Russia Doing at Sea?
Naval drills between China and Russia have taken place for more than ten years, with the size and the geographical scope of some of the drills growing larger from year to year.
For example, their drills under the “Joint Sea” series have involved anti-submarine warfare, air defence, search-and-rescue operations, anti-piracy drills, firing drills and sea replenishment exercises. It has been stated by the Congressional Research Service that the navies of both countries have conducted exercises in sensitive strategic regions, such as South and East China seas and the area around Japan.
This trend is significant as it does not confine itself to only one region. With each year, both China and Russia have shown an ability to conduct joint naval exercises in various maritime environments.
Why Japan Is Watching Closely
Japan is among those nations most directly impacted by the rising number of naval drills involving China and Russia.
Previous exercises have been conducted at locations which have seen both navies come near the sea approaches of Japan. In April 2026, reports emerged of Russian and Chinese navy groups transiting the southwestern sea region of Japan prior to entering the East China Sea.
It is noteworthy that Japan’s current assessment of its security situation has identified increased cooperation between China and Russia as a significant feature. This shows that Japan is gradually treating Sino-Russian military coordination within the broader context of its strategic situation.
Japan does not view China and Russia as forming a military alliance against it. Nevertheless, naval exercises can build up familiarity of operations and Japan has to factor in the potential for coordinated actions from various directions.
Is This a Formal China-Russia Military Alliance?
It does not quite fit.
The two countries have established a strong strategic bond but have no formal mutual defence treaty similar to that found in alliances such as NATO.
This is an important point. While joint military exercises indicate cooperation and interoperability, it does not necessarily imply that the two countries will be allies in case of a future war.
According to a report issued by the Congressional Research Service, there are shortcomings within the framework of this relationship in that the two military forces are not interoperable and military exercises can be extremely rehearsed.
The true significance of this emerging strategic relationship lies in the establishment of military coordination and signaling.
The Indo-Pacific Response Is Becoming More Complex
However, it should be noted that the regional response to this is not identical for all nations. There is an inherent variability in relations with China, Russia and the USA, so the response to Sino-Russian naval cooperation cannot be the same.
So, Japan responded more openly cautiously, while Indonesia continues to adhere to a policy of strategic independence and non-alignment.
It can be seen from recent events: the Indonesian navy stated that its August 2026 engagement with a Chinese warship near Taiwan was merely a routine military exercise, not an act of warfare. Meanwhile, Taiwan denounced the event as a provocation, yet Indonesia maintained that there were plans of conducting similar exercises with other states as well.
It shows the problem facing the whole Indo-Pacific region: states want more capabilities of ensuring maritime security, yet at the same time want to refrain from entering strict geopolitical alliances.
Taiwan Adds Another Layer to the Strategic Picture
Taiwan continues to be one of the most sensitive areas in the region.
Any rise in the naval activity of China near Taiwan will be monitored very closely, as there may be a likelihood of such exercises leading to increased military pressure, or creating an operational pattern, which may prove useful in the future, in case of a crisis situation.
The recent incident of naval activity of China and Indonesia near Taiwan has drawn the ire of Taiwan precisely because of its proximity to Taiwan. In fact, Indonesia described the interaction as a regular, non-military exercise.
Why the Pacific Is Becoming More Militarised
There is more naval cooperation between China and Russia, but that is part of a much broader expansion of military activity in the Indo-Pacific region.
This involves a broad range of increases to naval and missile operations from China, alongside an expansion in military exercises and defense cooperation from the US and regional allies.
Recent events include increasing anxiety over Chinese missiles in the Pacific, alongside efforts by Japan, Australia, the Philippines and other regional states to beef up their own defenses.
This leads to a feedback loop in which one country’s military preparations provide an excuse for other countries to do the same.
What results is an environment in the Indo-Pacific in which naval exercises have a dual purpose – improving military preparedness and signaling.
The Bigger Strategic Message
From the Chinese perspective, exercises with the Russians show that China has a military link with powers other than those within its immediate neighbourhood, and that it is able to function together with another major military power in a broader maritime environment.
From the Russian perspective, cooperation on the navy front allows it to remain a presence in the Asia-Pacific region, despite all the huge military and economic challenges presented by the Ukrainian conflict.
In terms of the regional states, the exercises have posed concerns regarding the level of coordination that could be achieved in a crisis situation by China and Russia.
It is unclear. However, the repetitive nature of the exercises makes the relationship strategically important regardless of any official alliance.
What It Means for India
India, too, has its role to play in the strategic landscape.
New Delhi has traditional military and diplomatic relations with Russia, yet is working to strengthen its ties with the US, Japan, Australia and other Indo-Pacific allies.
This gives India a unique situation. It needs to keep track of the rising maritime capabilities of China while also sustaining its strategic linkages with Moscow.
Thus, the increasing intricacies of the Indo-Pacific region increase India’s interests in maritime awareness, naval modernization, strategic alliances and freedom of navigation.
India does not have to worry only about whether China and Russia conduct joint military drills. It is more about what impact such actions can have on the balance of power in the Indian Ocean and wider Indo-Pacific region.
What Happens Next?
The most significant aspect to monitor will be whether such exercises become more common and geographically spread, as well as more complex in terms of operations.
In case the future joint military exercises begin featuring more intricate command structures, extended patrol zones, operations involving submarines, or joint air-sea operations, regional governments could interpret it as proof of closer military cooperation.
On the other hand, the lack of any formal alliance and different strategic interests between Beijing and Moscow should not be overlooked either.
Hence, the Indo-Pacific will hardly be characterized by one bloc including China and Russia on the one side and the United States on the other. Instead, the region is headed for a much more complex security dynamic.

Conclusion
Joint naval exercises involving China and Russia are not merely exercises for demonstrating cooperation anymore. The regularity of such exercises in important strategic locations is contributing to the overall Indo-Pacific security picture.
Growing concerns of Japan, sensitiveness of Taiwan in regard to China’s activities at sea, as well as efforts made by Southeast Asian states to retain their strategic autonomy, illustrate complexity of the regional reaction.
It cannot be claimed that China and Russia are now forming a formal military alliance due to regular joint naval exercises. Yet, what can be stated with certainty is that there is increased interaction and cooperation between two major military players.
For the Indo-Pacific region, this is a strategically important point.
What matters in reality is not one particular exercise of China and Russia but the tendency toward increased frequency of such exercises.
