The proposed India-Mexico Preferential Trade Agreement (PTA) reflects a deepening shift toward economic cooperation among Global South economies, as emerging markets seek to diversify supply chains and reduce reliance on traditional partners amid persistent geopolitical volatility, according to a new report. The two countries signed the Terms of Reference for the PTA in October 2026, formally opening the door to negotiations on market access, rules of origin, customs procedures, and trade facilitation.

Why the pact is taking shape now

Supply-chain disruptions over recent years and the gradual erosion of a unipolar economic order have created openings for emerging economies to forge bilateral partnerships rooted in mutual interest, the report noted. A key catalyst on the Mexican side was the country's decision to impose import tariffs ranging from 5% to 50% on more than 1,400 product categories from nations without existing trade agreements — a move that sharply raised the urgency for a formal bilateral arrangement with India.

Global South nations are also increasingly aligning for what analysts describe as economic self-defence against new and unpredictable tariff regimes imposed by larger Western economies. The India-Mexico framework is cited as a concrete example of this trend.

What India stands to gain

India's geographic and logistical advantage through Mexico is significant. Mexico's location gives India a stable entry point into broader South American markets, while simultaneously widening its access to North American-linked supply chains and industrial networks. During April–September 2026, India exported approximately $1.41 billion worth of high-value technology goods to Mexico, covering motor vehicles, auto components, two- and three-wheelers, aluminium, and iron and steel products.

According to the report, 'Indian pharmaceuticals, engineering goods and auto components are expected to meet real demand in a Mexican market actively seeking alternatives to concentrated supply.'

The emerging South-South model

The report frames the agreement within a broader South-South economic model, under which developing-nation partners trade high-value goods with each other and progressively build resilient supply chains to insulate themselves from Western economic dominance. The India-Mexico pact's focus on advanced sectors — automotive engineering, advanced electronics, and pharmaceuticals — is highlighted as evidence of this model moving beyond commodity exchange into technology-intensive trade.

The pact is described as marking a stage where Global South economies engaged in high-tech trade are constructing a mutually beneficial ecosystem, independent of Western intermediation.

What comes next

With the Terms of Reference now signed, formal negotiations are expected to advance across the agreed pillars of market access, rules of origin, and trade facilitation. The pace of those talks will likely depend on the political calendars of both nations and the broader trajectory of global trade tensions. If concluded, the PTA would be among India's first preferential trade arrangements with a major Latin American economy, with potentially significant implications for Indian exporters and for the broader South-South trade architecture.
