Enforcement Gaps in Maritime Law Expose Risks in Trade Routes

Nearly one third of global trade passes through the South China Sea where one state claims sovereignty over 90% of the area via its self-declared 九段線 (Traditional Chinese for the Nine-dash line). This assertion conflicts directly with the maritime rights that the United Nations Convention on the Law of the Sea grants to other coastal states. The Philippines brought the matter to arbitration under the convention in 2013. The Permanenteng Hukuman ng Arbitrasyon (Permanent Court of Arbitration in Tagalog) issued its 2016 award which determined that the claimed historic rights held no legal validity under the convention.

Several features occupied in the area qualified only as rocks or low-tide elevations incapable of generating exclusive economic zones. The tribunal also found violations of sovereign rights through interference with fishing and petroleum exploration inside the Philippine zone. China has refused to recognize or implement the decision. Such refusal underscores how the convention creates a compulsory dispute resolution process through its articles and annex yet provides no standing body to enforce awards or impose sanctions on noncompliant states.

The regime therefore depends on voluntary adherence from participants. Powerful actors can set aside rulings when geopolitical priorities prevail. In this context the continued militarization of disputed features after the award illustrates the practical limits of the system. States have responded with political tools such as freedom of navigation operations to contest excessive claims and reinforce open access. These patrols support principles of open navigation yet they rely on geopolitical leverage instead of judicial authority. Scholars note that reliance on political measures rather than legal ones erodes the legitimacy of the broader international order.

Now, the تنگه هرمز (Strait of Hormuz in Farsi) presents a parallel set of challenges though the disagreements center on interpretation rather than outright noncompliance. 20% of the world oil supply transits this narrow passage connecting the Persian Gulf to the Arabian Sea. The United States views the strait exclusively as an international waterway subject to transit passage standards drawn from the convention. Iran regards the waters as part of its territorial sea governed by older principles of innocent passage.

Under those earlier standards foreign vessels enjoy passage rights provided they cause no harm to coastal security and refrain from non-innocent activities. Iran and Oman as bordering states retain authority to adopt safety and environmental rules, yet they lack the power to suspend innocent passage when the waters form an international strait. Tehran has asserted the right to suspend traffic in its portion of the strait and to impose tolls on vessels. Washington considers these steps illegal. Iran in turn sees US efforts to block passage as a grave violation of sovereignty.

In fact, neither country has ratified the convention in full. The United States has signed no part of it while Iran signed but has withheld ratification. This shared distance from the convention leaves both parties drawing on different legal foundations. The United States maintains that transit passage rules apply as customary law and conducts regular freedom of navigation patrols to uphold them. Iran counters that it qualifies as a persistent objector to the newer transit passage concept, having opposed it consistently during negotiations and upon signing the convention. Legal experts remain divided on whether transit passage has achieved customary status, though many specialists in the field lean against that conclusion. The resulting mismatch in perspectives complicates efforts to manage tensions amid ongoing military and economic pressures.

These two situations together form a coherent picture of vulnerability in the maritime legal order. One case reveals the absence of enforcement tools once a binding decision issues. The other exposes fundamental divergence over which rules even apply to the same geographic feature. In both instances, key chokepoints essential to global commerce sit at the center of unresolved legal friction. The convention aims to establish stable zones and rights, yet its effectiveness falters when states prioritize strategic interests over collective commitments. As a consequence, rulings risk becoming symbolic gestures rather than operational realities.

Corporate leaders responsible for supply chain resilience now face heightened uncertainty in route planning and risk assessment. Energy firms that move crude through the Strait of Hormuz must weigh the possibility of tolls blockades, or sudden restrictions, that arise from clashing interpretations. Shipping operators active in Biển Đông, the South China Sea in Vietnamese ("East Sea" literally), contend with the potential for interference in exclusive economic zones despite clear arbitral findings. Public-benefit corporations focused on sustainable development encounter similar exposure when their projects involve maritime resources or cross-border logistics. The absence of reliable enforcement mechanisms amplifies these operational risks and elevates the cost of compliance monitoring.

In this context, localization departments within multinational organizations play an increasingly central role in mitigating such exposures. They translate technical legal texts treaties and regulatory updates for stakeholders across multiple jurisdictions where wording matters because subtle differences in how terms like Innocent Passage or Transit Passage translate can influence local interpretations and compliance postures.

When documents reach audiences in the Pacific Islands, where maritime economies depend on stable access to exclusive economic zones, accurate conveyance of these concepts supports informed decision-making. The same holds for communications that address freedom of navigation operations or arbitral outcomes, and misalignment in translated materials can compound existing tensions and thus slow collaborative efforts.

Now, the convention itself reflects a deliberate balance between binding obligations and respect for state sovereignty. To put it simply, architects of the framework sought broad participation by avoiding coercive elements that might deter ratification. While this choice preserves consent, it also leaves the system reliant on diplomatic and reputational pressure to secure adherence. In practice such pressure proves inconsistent when powerful states decline to implement awards. The South China Sea arbitration is as a prominent example where a clear legal victory yielded limited practical change. Similar dynamics appear in the Hormuz exchanges where each side invokes different historical precedents to justify its position.

Businesses that operate in or near contested waters, therefore, incorporate scenario planning that accounts for legal volatility. They monitor freedom of navigation patrols as indicators of state resolve. They also track scholarly debates over customary law because shifts in consensus could alter the baseline for acceptable conduct. For organizations with Pacific interests, the stakes extend to resource management and trade partnerships. Island nations that have embraced the convention rely on its provisions for defining their maritime entitlements. Any erosion in the perceived authority of the framework affects confidence in long-term planning.

That said, efforts to strengthen the system have surfaced in various forums, though progress remains incremental. Proposals include enhanced regional cooperation mechanisms or incentive structures that reward compliance. Until reforms take hold, however, the current arrangement favors those with the capacity to project power over those who depend on predictable legal outcomes. This reality shapes how corporations allocate resources for insurance legal review and contingency routing.

The Hormuz case adds another layer by demonstrating how non-ratification creates parallel legal universes. States that stand outside the convention still invoke its concepts selectively while anchoring their positions in pre-existing conventions such as the 1958 Territorial Seas Convention or the 1949 Corfu Channel ruling from the International Court of Justice. The United States for instance applies transit passage standards it considers customary even without formal membership. Iran leverages its persistent objector status to resist the same standards. Such selective engagement fragments the uniformity that the convention seeks to promote.

Corporate localization teams, therefore, prioritize translators who grasp the legal substance and the cultural contexts in which those texts will circulate. In Pacific Island settings, where oral traditions and communal governance intersect with formal law, the manner of presentation influences acceptance and implementation. Specialists who can commute betwen these worlds ensure that strategic intelligence arrives in forms that sound good locally.

As tensions persist, the need for clear communication grows. We never say it enough, but organizations that invest in high quality translation of maritime legal materials position themselves to anticipate developments instead of reacting to them. They reduce exposure to miscommunication that could escalate disputes or delay projects. They also contribute to a broader environment in which rules-based order means a lot.

Consultation with language specialists versed in Pacific Island contexts remains essential for turning complex legal analyses into actionable intelligence. This approach supports sustainable business ventures by aligning global standards with local realities and by fostering the mutual understanding required for enduring partnerships.
