Naypyidaw, March 20 (NationPress) Vietnam's defiance against Chinese dominance in the South China Sea serves as a dual purpose: a national defense of its sovereignty and a commitment to uphold global law. The deterioration of relations between these two nations reflects a precarious trend—one where China's aggressive stance threatens to undermine the fragile stability of the Southeast Asian region, as reported.

A recent article from Myanmar's 'Mizzima News' emphasizes the necessity for the international community to remain vigilant, support diplomatic resolutions, and resist China's coercive maritime actions. Failure to act may inadvertently validate China's assertive methods and jeopardize the established rules-based international order.

“China's growing assertiveness in the South China Sea ranks among the most urgent geopolitical challenges of our era. Central to this conflict is Vietnam, a nation with a long history of resisting northern control, now grappling with Beijing’s assertive maritime expansion. The worsening ties between China and Vietnam extend beyond a simple bilateral dispute; they signal potential instability throughout Southeast Asia, with significant ramifications for navigation freedom, international law, and regional security,” the report articulates.

The report highlights that China's expansive claims, illustrated by its notorious “nine-dash line,” encroach upon Vietnam’s territorial assertions over the Paracel and Spratly islands.

This assertion was rejected in 2016 by the Permanent Court of Arbitration in The Hague, which ruled that China lacked legitimacy under international law.

“In spite of this ruling, Beijing has escalated its island-building efforts, militarized artificial islands, and deployed coast guard ships to assert its dominance. These actions have compromised Vietnam’s sovereignty and weakened ASEAN’s endeavors to create a binding Code of Conduct. Vietnam has countered by reinforcing its holdings in the Spratlys, yet the disparity in power remains significant,” it adds.

Recent developments from 2025 to 2026 indicate an escalating volatility in the dispute, as China amplifies coast guard operations and intensifies naval patrols in contentious waters, frequently “harassing” Vietnamese fishing boats.

In retaliation, Vietnam has fortified its infrastructure on Spratly Island, enhancing airstrips and surveillance systems, signaling its determination to counter any further encroachment.

“Simultaneously, the United States has bolstered military ties with the Philippines, prompting reciprocal naval deployments from China. ASEAN–China discussions on a Code of Conduct have stalled, with fundamental differences obstructing any substantial progress. These developments illustrate that the situation extends beyond a bilateral issue, intertwining with broader US–China tensions and regional security dynamics,” the report notes.

“The world must be wary of China's assertive strategies. Beijing's maneuvers in the South China Sea are not isolated incidents; they embody a larger strategy of coercion and expansion. If left unchallenged, this approach could destabilize the entire Southeast Asian region, embolden China to defy international maritime law, and undermine global sovereignty norms. Vietnam's challenges reflect the perils faced by smaller nations in the face of a rising hegemon,” it further emphasizes.

In discussing China's expansionist policies, the report concludes, “The South China Sea transcends a mere regional dispute; it is a significant global security issue affecting trade routes, energy supplies, and the credibility of international law.”
