Supporting evidence to my prior response on this post:Not sure if this move is aimed at intimidating China but I'm pretty sure it will have no such effect
"This study finds that Beijing anticipates an intensifying naval rivalry with Tokyo in the coming years. According to the Chinese narrative, a combination of competitive impulses, insecurity, ill will, and deeply ingrained cultural traits have inclined Japan to perceive China’s naval ascent as a grave threat. Japan, so goes this logic, will do its utmost to frus-trate Chinese maritime ambitions. In conjunction with its U.S. ally, Tokyo will organize a coalition of like-minded maritime powers to surround and counterbalance China at sea. In Chinese eyes, Sino-Japanese maritime competition and naval confrontation are virtually fated."
The Chinese have anticipated this move years ago if we're to believe the Japanese study.
