How could an Aukus role for Tokyo affect China's ties with Japan?

Description

Ryosuke Hanada, a researcher at Sydney’s Macquarie University, argued that hurdles still loomed for Japan to formally join Aukus.  

“Japan’s formal entry requires synchronisation of rules and actions with Aukus members,” Hanada said, citing highly restrictive arms-trade rules and a lack of tough anti-espionage laws.

“At this stage, there is nothing more than consideration of Japan’s future participation or a project-by-project basis cooperation in some areas,” he added.
