Moscow: As tensions continue to simmer between global powers, Russia and China have launched a joint naval exercise in the Sea of Japan, even as the US announced the deployment of two nuclear submarines near Russian waters.

The Pacific Fleet of the Russian Navy confirmed the commencement of the drill, dubbed "Maritime Interaction-2025", which includes large submarines, destroyers, and artillery strike simulations. Notably, diesel-electric submarines from both sides are actively participating, signaling a show of undersea force.

The exercise comes at a critical moment, following a provocative statement by former Russian President Dmitry Medvedev, who warned US President Donald Trump to refrain from issuing threats or sanctions against Russia. In response, Trump declared the deployment of nuclear submarines, further escalating geopolitical tension.

Though Moscow has not officially reacted to Trump’s submarine move, the timing of this joint exercise is seen by analysts as a strategic message to the West, especially NATO.

Russia and China, whose military cooperation has significantly deepened since signing a "no limits" strategic pact in early 2022, have conducted multiple joint military drills in the past three and a half years.

Their latest naval venture appears aimed at reinforcing their maritime dominance and sending a united front against US-led influence in the region. The Maritime Interaction-2025 exercise is scheduled to continue through Tuesday.
