Former Senior Associate Justice Antonio T. Carpio has warned that China’s increasingly aggressive diplomatic posture in Manila may be part of a broader strategic preparation to assert control over Scarborough Shoal — a move that could fundamentally alter the balance of power in the West Philippine Sea. In a recent interview, Justice Carpio observed that the arrival of a new Chinese ambassador appears to mark a shift toward a more confrontational tone, coinciding with Beijing’s announced plan to establish a so-called “nature reserve” in Scarborough Shoal. Based on China’s past conduct in Fiery Cross Reef and Mischief Reef, Justice Carpio cautioned that environmental or scientific pretexts often serve as the first step toward militarization, ultimately transforming occupied features into full-scale air and naval bases.
Justice Carpio explained that control of the South China Sea requires only three strategic air-naval hubs — in the Paracels, the Spratlys, and Scarborough — and China has already secured two of them. Scarborough Shoal remains the final strategic gap. He suggested that China’s abrasive rhetoric and provocative embassy behavior may be part of a deliberate effort to bait the Philippines into a confrontation that could later serve as justification for escalation. To counter this, Justice Carpio urged the Philippine government to shift from reactive diplomacy to proactive legal and strategic action by internationalizing the Scarborough Shoal issue, filing new arbitration cases under UNCLOS, enforcing existing arbitral rulings, and drawing global attention to China’s looming violation of the 2002 Declaration of Conduct. He stressed that placing Scarborough Shoal in the international spotlight — while strengthening security partnerships and alliances — remains the most effective way to deter unilateral Chinese action and defend Philippine sovereignty.
