Tensions between China and the Philippines continue to rise, with China obstructing Philippine ships and issuing regulations to detain foreign ships for up to 30 days for illegal entry. The Philippines is resisting China's attempts to encroach on its territory and is strengthening its defense cooperation with the US and its allies. Despite China's attempts to win over the Philippines through investments and access rights for Filipino fishermen, these efforts have not been successful. The Philippines is also investigating China's influence in Filipino society. The situation is prompting concerns about China's aggressive behavior and calls for a more diplomatic approach, or face the possibility of driving the Philippines closer to the US and generating anti-Chinese sentiment.
