China Coast Guard Exercises ‘Jurisdiction’ in Japan’s Exclusive Economic Zone

China's explicit assertion of jurisdiction in Japan's EEZ and defiant rejection of international maritime law signals aggressive expansion of grey-zone coercion in the Western Pacific, directly threatening the rule-based order on which Australia's alliance architecture and resource security depend. This pattern of incremental boundary-testing and legal revisionism mirrors tactics that could escalate toward Taiwan and directly pressure Australia's alliance partners (Japan, US), potentially forcing Australia into earlier or deeper strategic commitment.
