No end in sight to spat between Japan and China over Taiwan, as neither Tokyo nor Beijing shows signs of backing down.

The Japanese leader’s candor over Taiwan brought the shared regional stakes out into the open, and the U.S. must stand behind its ally.

The remarks come amid the two countries’ worst diplomatic crisis in years, after the Japanese prime minister said a Chinese attack on Taiwan could trigger a military response from Tokyo.

Taiwan and Japan voiced concern on Friday over Chinese military activities in the region, after Reuters reported that Beijing had deployed a large number of vessels across East Asian waters this week in its largest maritime show of force to date.

China continued to voice its frustration with Japan after new comments from Prime Minister Sanae Takaichi reaffirming Tokyo’s long-held position that it understands and respects Beijing’s view on Taiwan.

Taiwan, the world leader in cutting-edge semiconductor production, has launched a program to attract Japanese students to fill a worker shortage in the industry.

Chinese nationals felt it was unpatriotic to hide the country's name, while other netizens from other areas did not want their passports used seemingly as subterfuge. According to ETtoday, the kerfuffle started when a Chinese netizen said he was using the cover when travelling to Japan to avoid any unpleasant encounters.
