Examine the role of UN Security Council vetoes in the governance of freedom of navigation.

Freedom of navigation through international straits rests on the UNCLOS regime of transit passage, but its enforcement depends on the Security Council. The veto therefore makes protection of sea lanes a political variable rather than a guaranteed right — as the 2026 Strait of Hormuz crisis showed.

Where the veto permits collective action

• The Council is the only body that can authorise binding measures — escorts, sanctions, enforcement — for shipping security.
• Resolution 2722 (2024) demanded Houthi attacks on merchant vessels in the Red Sea cease; it passed 11-0-4 because China and Russia abstained instead of vetoing [1]. Restraint in veto use, not its absence, kept the Council effective.

Where the veto blocks governance

• In April 2026, a Gulf States' draft to coordinate defensive escorting through Hormuz won 11 votes but failed on China and Russia's veto (2 against; Colombia, Pakistan abstaining) [2].
• Russia argued the text was "unbalanced... confrontational" and cast Iran as the sole source of tension [2] — navigation became a question of bloc alignment.
• A later Council debate could only urge restoration of navigation and condemn the waterway's use as a "bargaining chip" [3] — declaratory pressure without a mandate.

Implications of paralysis

• Daily transits fell from over 100 vessels to between 2 and 16 [4]; global oil supply fell 10.1 mb/d in March 2026 and Brent rose about 65% [5].
• The burden shifts to non-members: the ILO projected real labour incomes falling by up to $3 trillion by 2027 [4]. India, overwhelmingly dependent on Gulf crude, absorbs imported inflation without any vote in the veto.

Partial correctives

• The General Assembly's post-veto debate under the veto initiative supplies accountability and voice, not enforcement [6].
• UNCLOS rights, regional cooperative escorting and coalition patrols continue functioning outside the Council.

The veto is thus simultaneously the keystone of great-power buy-in and the chokepoint of maritime governance. A durable way forward lies in voluntary veto-restraint pledges on global-commons issues, strengthened Assembly follow-up, greater use of ICJ/ITLOS advisory routes, and regional escorting arrangements — so that transit passage functions as an unpurchasable common good, consistent with UNCLOS and SDG 14 and 16.
