The territorial dispute between China and the Philippines in the South China Sea is intensifying. China's aggressive actions, the resulting damage to the Philippines, and the increased military aid from surrounding countries like the US and Japan are escalating tensions in the region. This conflict transcends a simple territorial issue, significantly impacting international relations and is expected to greatly influence the security of the East Asian region. The Philippines' President Marcos's shift towards an anti-China policy is a key factor in this dispute, interpreted as a strategic choice to counter China's influence expansion through strengthening ties with the US. The military responses and diplomatic efforts of various countries are crucial to watch. Ultimately, the South China Sea dispute is likely to escalate into a global security issue.
