Australia, the US, and the UK are set to test a new artificial intelligence (AI) technology for tracking Chinese submarines under the AUKUS defence agreement following a meeting of ministers on Saturday. What’s put a rocket under the decision are concerns about China’s aggression in Asia-Pacific waters, including the recent injuries suffered by Australian naval divers after sonar blasts from a nearby Chinese warship off Japan’s coast. Aussie Defence Minister Richard Marles said the incident “absolutely highlights the need for speed in this arrangement”. And to get up to speed, Australia is set to receive $3 billion worth of military training and equipment from the US. Meanwhile, the US’s top general is waiting on a response from China about getting military-to-military ties back on track. Last month, Presidents Joe Biden and Xi Jinping agreed to re-establish communications in order to prevent any misunderstandings from blowing up into an armed conflict.
