India-Brazil Critical Minerals MoU: Supply Chain Diversification and the Pax Silica Context
India and Brazil signed a Memorandum of Understanding (MoU) on rare earths and critical minerals during Brazilian President Lula da Silva's state visit to India on February 21, 2026
The MoU covers cooperation across the full mineral value chain — exploration, mining, processing, recycling, and refining — to strengthen supply chains and enhance competitiveness
This came days after India formally joined the US-led Pax Silica initiative (February 20, 2026), a coalition focused on securing supply chains for the silicon stack including critical minerals, semiconductors, and AI infrastructure
Unlike Pax Silica, Brazil is not a member of the initiative; the India-Brazil MoU operates independently as a bilateral arrangement
The deal builds on India's significant import dependence — nearly 100% for minerals like lithium, cobalt, and silicon — and Brazil's vast mineral reserves
Pax Silica: US-Led Critical Technology Supply Chain Alliance
Pax Silica is a strategic international initiative launched by the US Department of State in December 2025, aimed at building secure and resilient supply chains for the "silicon stack" — spanning critical minerals, energy, advanced manufacturing, semiconductors, AI infrastructure, and logistics. The name is a reference to the dominant role of silicon in modern technology. India signed the Pax Silica declaration on February 20, 2026, at the India AI Impact Summit in New Delhi.
While Pax Silica sets a framework for ally-based supply chain security, the India-Brazil bilateral MoU is a complementary arrangement that specifically targets mineral sourcing from a non-aligned major mineral producer, giving India greater flexibility and diversification.
India's Critical Minerals Strategy: NCMM and KABIL
India's vulnerability in critical minerals is well-documented: it imports nearly 100% of its requirement for lithium, cobalt, nickel, and several rare earth elements. In response, India launched the National Critical Minerals Mission (NCMM) in 2025 — a seven-year program — and established Khanij Bidesh India Ltd (KABIL) in 2019 to acquire overseas mineral assets. The Mines and Minerals (Development & Regulation) Amendment Act, 2023, delisted lithium, niobium, and titanium from atomic minerals, enabling private sector participation in exploration.
Brazil offers precisely the minerals India lacks domestically. Brazil holds 21 million tonnes of rare-earth-oxide equivalent, 2.7 billion tonnes of bauxite, 270 million tonnes of manganese, 0.4 million tonnes of lithium, and is among the world's top iron ore producers. The MoU creates a bilateral channel that complements KABIL's ongoing acquisition strategy.
MoU vs Treaty: Distinctions in International Law
In international law, instruments of inter-state cooperation vary in their legal character and binding force. A Memorandum of Understanding (MoU) is generally a non-binding political commitment that sets out broad intentions and areas of cooperation without creating legally enforceable obligations under international law. A Treaty, by contrast, is a binding international agreement governed by the Vienna Convention on the Law of Treaties (1969) that creates legally enforceable rights and obligations.
The India-Brazil arrangement being an MoU signals early-stage commitment — establishing the cooperation framework before moving to binding procurement contracts or joint venture agreements in the minerals sector.
India-Brazil Bilateral Relations: IBSA and BRICS Context
India and Brazil are part of several multilateral groupings — BRICS (Brazil, Russia, India, China, South Africa; established 2009, expanded 2024), IBSA (India, Brazil, South Africa; trilateral dialogue forum established 2003 in Brasilia), and G20. Both are leading democracies of the Global South and have historically aligned on issues of multilateral reform, including UNSC expansion (both favour reform) and WTO dispute resolution.
The MoU deepens a relationship already anchored in multilateral forums. Brazil's position as a non-aligned, resource-rich major economy makes it a strategically important partner for India's minerals diversification strategy that is independent of great-power competition.
