The naval exercises were entirely legitimate and professional, conducted in international waters far from Australia's coastline, with appropriate safety notices issued according to international practices. China, as a major regional power, has every right to conduct military activities in different parts of the world, and these drills should not be overinterpreted or cause undue concern.
The no-notice live firing exercises represent deliberate and dangerous behavior in a peaceful neighborhood, causing unnecessary disruption to civilian aviation and undermining recent diplomatic progress. The lack of proper advance notice falls short of expected international standards and raises concerns about China's military intentions in the region.
