The Philippine forces had discovered 48 Chinese fishing vessels being guarded by warships within the country's Exclusive Economic Zone (EEZ).
The fishing vessels were spotted near the Philippine-claimed Union Banks, which are located in the South China Sea.
The Philippine government immediately expressed concern over the presence of the Chinese vessels, as they were operating in waters.
The Philippine Department of Foreign Affairs (DFA) issued a statement condemning the presence of the Chinese vessels, calling it a clear violation.
The Philippine military conducted aerial surveillance and confirmed the presence of Chinese warships escorting the fishing vessels.
The United States, a long-time ally of the Philippines, expressed its support for the Philippines' territorial rights and called for a peaceful resolution.
The incident escalated tensions between China and the Philippines, as territorial disputes in the South China Sea have been ongoing for years.
The Philippine government vowed to protect its sovereignty and said it would explore diplomatic and legal avenues to address the issue.
