From the perspective of Beijing, the actions taken by the Chinese Coast Guard are necessary measures to protect what it defines as its sovereign territory. China maintains that its historical rights over the South China Sea are clear and that foreign vessels, including those from the Philippines, are violating these boundaries by conducting supply missions to illegal outposts. The use of water cannons is framed by Chinese officials as a restrained, non-lethal method to deter unauthorized entry and enforce maritime law.
Proponents of this approach argue that China is simply responding to what it perceives as provocative behavior encouraged by external powers, particularly the United States. By maintaining a constant presence and utilizing assertive tactics, China aims to discourage other nations from challenging its territorial claims. This strategy is intended to solidify Beijing's control over the region and prevent the erosion of its maritime borders, which it views as a core national interest.
Furthermore, supporters emphasize that China is acting to prevent the permanent occupation of features that it believes belong to its territory. The grounded Philippine ship, the BRP Sierra Madre, is seen by Beijing as a symbol of illegal encroachment that must be countered. For those who back this policy, the primary goal is to ensure that China's regional influence remains unchallenged and that its territorial integrity is defended against any perceived encroachment by neighboring states or their international allies.
Ultimately, this perspective holds that regional stability is best achieved when China's claims are respected. By pushing back against supply missions, China is signaling that it will not tolerate actions that undermine its sovereignty. This stance is seen as a proactive defense of national security, ensuring that the South China Sea remains under the control of the regional power that claims it, rather than being subject to the influence of outside forces.
