Japanese politician Sanae Takaichi initially signaled an interest in building diplomatic ties with China, attempting to balance strategic economic interests with security concerns regarding Taiwan. Public discourse at the time was divided on whether her stance could repair existing political rifts.

However, diplomatic tensions escalated following Takaichi’s suggestions that Tokyo might intervene if China attacks Taiwan. This led to a formal request from Japan for China to show ‘appropriate respect’ toward the Prime Minister after a Chinese Foreign Ministry spokesperson omitted her official title. 

Concurrently, former Taiwanese President Tsai Ing-wen warned of intensifying ‘gray zone’ operations from China, including cyberattacks, economic coercion, and increased maritime activity, noting that these actions aim to undermine stability without triggering open conflict.
