In a significant escalation of tensions in the disputed South China Sea, US President Joe Biden has issued a stern warning to China, stating that the United States will defend the Philippines in the event of any attack in the contested region. President Biden’s comments followed recent collisions between Filipino and Chinese vessels in the disputed waters, further heightening the longstanding maritime dispute.

Emphasizing the US’s unwavering commitment, Biden reiterated the “ironclad” defense commitment to the Philippines, citing the Mutual Defense Treaty signed in 1951 between the US and its former colony. The treaty binds both nations to defend each other in the event of an armed attack. Biden stated firmly that any attack on Filipino aircraft, vessels, or armed forces would invoke the Mutual Defense Treaty between the US and the Philippines.

The Philippines has contested China’s claims to the waters, taking measures such as cutting floating barriers and inviting media to document what it perceives as Beijing’s provocative actions at sea. The recent collisions between Chinese coast guard ships and Filipino vessels occurred within the Philippines’ Exclusive Economic Zone (EEZ), leading to accusations from Manila that the Chinese boats deliberately targeted the Philippine vessels.

In response to Biden’s warning, Chinese foreign ministry spokesperson Mao Ning asserted that the US had no right to interfere in the issue between China and the Philippines. She stressed that any US actions in defense of the Philippines must not infringe upon China’s sovereignty and maritime interests in the South China Sea.

President Biden and his administration’s strong stance signifies an escalation in the South China Sea dispute and raises concerns about the potential for further conflict in the region.
