Tension between Japan and China has escalated over the new Japanese leader's suggestion Tokyo could intervene militarily if Beijing attacks Taiwan.

China advised its citizens Friday to refrain from traveling to Japan in the near future. It cited earlier attacks against Chinese in Japan and what it called Prime Minister Sanae Takaichi 's "erroneous remarks" on Taiwan, which it said undermined the atmosphere for China-Japan exchange.

The opinion poll comes at a time when a diplomatic spat between Tokyo and Beijing has intensified following Takaichi's remarks related to Taiwan. The Japanese premier said on November 7 that a Chinese attack on Taiwan could amount to a "survival-threatening situation" and trigger a potential military response from Tokyo.

Both countries have summoned each other’s ambassadors after Prime Minister Sanae Takaichi said a Chinese attack on Taiwan could draw a military response from Tokyo.
