How did China respond to Japan's decision to allow Taiwanese individuals to list Taiwan as their place of origin in family registries?

China responded firmly to Japan's policy change by urging Japan to abide by the One China principle. The Chinese Foreign Ministry spokesperson explicitly warned Japan against using 'gimmicks' on the Taiwan question and cautioned the Japanese government not to send any conflicting or wrong signals regarding Taiwan's status. This response reflects China's consistent position that Taiwan is an inseparable part of Chinese territory and demonstrates Beijing's sensitivity to any actions that might imply recognition of Taiwan as a separate entity from China.
