China and Russia do not have a common defence treaty, but increasingly act as 1 military organism. During the Joint Sea-2026 maneuvers off the Qingdao coast, they first launched submarines together, and immediately afterwards they set off on a joint patrol. For the West, and especially for the east flank of NATO, it is simply a signal that a block is being born, which forces no longer request to be written on paper.
The maneuvers that decision the border
Joint exercises Joint Sea-2026 ended in mid-July at Qingdao Military Port, on the east coast of China. In 1 week of maneuvers, the 2 fleets exhibited about 10 ships and aircraft and support units. The breakthrough was the participation of submarines: for the first time since the launch of this series of exercises in 2012, there was a Chinese kind vessel 039B and a Russian class unit Kilo. The crews practiced joint reconnaissance and anti-aircraft and anti-missile defenses, and after the maneuvers were completed, they switched to a joint sea patrol.
An increasingly dense network of cooperation
It's not an episode, it's a trend. Almost a 3rd of all joint Chinese-Russian exercises since 2003 have been in the period after 2022 and their scope has expanded to land, air and sea. After the Xi Jinping and Vladimir Putin summit in Beijing, both states announced a deepening of military cooperation and the expansion of joint air and sea patrols. Beijing takes note of the Western readings of these actions: the Ministry of Defence of China called for Russia to look at cooperation with Russia "objectively and rationally" as a regular cause.
The device is not just a maneuver.
Joint exercises are the most visible, but not the only layer of this cooperation. Behind the fleet shows stands a much wider network of connections: trade, technology and diplomatic back covering in global forums. The Russian war economy is mostly based present on exchanges with China, and the joint air patrols of both countries have repeatedly approached the zones of Western work in the Pacific. This is the full thing, not the single maneuvers, that creates the "machine", which Western analysts are increasingly talking about. The closer the coordination, the harder it is to treat Beijing and Moscow as 2 separate decision-making centres.
Why “without a Treaty”
The absence of a formal alliance here is simply a choice, not a weakness. The defence treaty would bind hands and force automatic commitments, and loose yet increasingly dense coordination would give both powers: real interoperability without political muzzle and without clear responsibility. It is simply a model of an alliance on demand, in which joint command, procedures and patrols practice so long, until in the event of a crisis they can be launched without signing anything.
What this means for Poland
One consequence is most crucial for Warsaw. The machine, which arises in the Pacific and in the waters of East Asia, binds the attention and resources of the West, drawing them distant from the European theatre. Each joint patrol of China and Russia is simply a test of Western cohesion and a reminder that the east flank of NATO is not isolated from what is happening thousands of miles away. The increasing authoritarian block does not request a treaty to change the arrangement of forces. The question is whether the West can respond equally coherently before the “soy without a treaty” begins to dictate terms.
