'Sanctions diplomacy has become an instrument of economic coercion in a multipolar world.' Discuss with reference to India's response to U.S. tariff threats over Russian oil imports.

Sanctions diplomacy today works less by punishing the target state than by taxing third countries that trade with it. The Lindsey O. Graham Sanctioning Russia and Iran Act, 2026, which authorises tariffs of up to 100% on the five largest importers of Russian crude or gas, places India squarely inside this coercive architecture [1].

Sanctions as an instrument of economic coercion

• Extraterritorial reach: the penalty falls on buyers, not on Russia; Indian exporters who never handled Russian crude face costlier access to the U.S. market [1].
• Deliberate discretion: the tariff is permitted, not mandated, and can be waived once the U.S. President certifies it is in the national interest [1]. The resulting uncertainty is itself the bargaining lever.
• Legitimacy deficit: no UN Security Council decision underpins it. UNGA debates record the view of many developing states that unilateral coercive measures hinder development and sit uneasily with the UN Charter [3].
• Multipolar effect: simultaneously targeting several large economies accelerates alternative payment routes and hedged alignments rather than compliance.

India's calibrated response

• Autonomy asserted: energy sourcing is defended as a commercial decision driven by national interest, not external direction.
• Diversification as insurance: oil PSUs now procure crude from about 40 countries, with roughly 70% of imports arriving by routes outside the Strait of Hormuz [4].
• Quiet negotiation over confrontation: India has sought clarity, exemptions and product-level carve-outs through engagement rather than public rupture [1].
• Rules-based ground: GATT Article XXI's security exception, first interpreted in Russia — Traffic in Transit (2019), demands a genuine security nexus [2] — one that a tariff on Indian textiles cannot satisfy.

Coercion has thus migrated from punishment to leverage. India's blend of supplier diversification, patient negotiation and legal argument protects both energy security and strategic autonomy. Sustaining it requires wider export markets, deeper strategic reserves, and consistent advocacy for UN-anchored, multilateral sanctions norms.
