China Warns Citizens Against Japan Travel Amid Deepening Taiwan Row

China has advised its citizens to avoid traveling to Japan, escalating a diplomatic feud over Taiwan. The warning follows comments from Japanese Prime Minister Sanae Takaichi, who stated that an armed attack on Taiwan could justify a military response from Tokyo under its "collective self-defense" policy. Both nations have summoned each other's ambassadors over the remarks and a subsequent inflammatory social media post by a Chinese diplomat. The row signals rising tensions between the two Asian powers.
