Saudi Arabia and Indonesia meet at a rare point of industrial complementarity: Saudi Arabia is a global force in petrochemicals thanks to its hydrocarbon resources, and Indonesia is rich in mineral resources such as nickel, which is central to battery manufacturing. That complementarity featured strongly in the 2025 agreements.
Petrochemicals: a Saudi strength looking for markets
Saudi petrochemical companies are seeking growth markets beyond the traditional ones that have reached maturity. Indonesia is among the best of them, for two reasons.
The first is that its manufacturing base is expanding fast: packaging, automotive, construction and home appliances. All of these consume polymers and plastics intensively.
The second is that its domestic output of these materials does not cover its demand, making it a net importer. A net importer of a commodity whose dependent industries are growing is the best thing an exporter can find.
The opportunity does not stop at exporting. The higher-value model is investing in conversion plants inside Indonesia that use Saudi feedstock, which turns the relationship from selling a commodity into a production partnership.
Mining: nickel and the future of batteries
Indonesia holds vast nickel reserves, a metal at the heart of electric vehicle battery manufacturing. For years the Indonesian government has pursued a policy encouraging domestic processing rather than exporting raw ore, in order to keep the added value inside the country.
That policy creates an opening for the foreign investor rather than closing the door on them: capital and expertise are needed to build processing and manufacturing facilities inside Indonesia.
Saudi Arabia has a declared interest in critical minerals supply chains as part of its move to make mining a third economic pillar. Where that interest meets Indonesian resources, a door opens to long-term partnerships in a sector expected to keep growing as the global electric vehicle market widens.
Shared supply chains
What makes this complementarity distinctive is that it is not a simple exchange between a seller and a buyer, but something that can develop into a shared value chain.
Picture the full path: Indonesian nickel processed in a joint facility, Saudi chemicals entering battery manufacture, and a finished product exported to third markets. In that model neither side sells to the other; together they build a product they sell to the world.
This kind of partnership is the hardest to establish and the most durable, because both sides’ interests become one rather than opposed.
What do mid-sized companies need?
These projects may look like the preserve of giants, but real opportunities for mid-sized companies form around them: engineering services, specialised equipment, transport and storage, maintenance, and environmental and regulatory consultancy.
The key is early presence: introducing your capabilities during the study and development phase, not after the main contracts are awarded.
