Chile and Mercosur: Close, but Not Bound
Chile has been connected to Mercosur for nearly thirty years — and has never joined. That tension is not an oversight. It is a deliberate trade strategy.
Chile is close to Mercosur by design, but not institutionally bound to it.
ACE No. 35 gives Chile deep commercial access to the bloc while associated-state status preserves the flexibility to maintain a global trade strategy centred on Asia, North America and Europe.

Core market reading:
Chile uses Mercosur as a regional anchor, not as the centre of its trade architecture. The value of the relationship lies in controlled proximity: enough access to matter, enough distance to remain globally flexible.
Chile has been connected to Mercosur for nearly thirty years — and has never joined. That tension is not an oversight. It is a strategy.
ACE No. 35: The Commercial Foundation
The institutional framework has long been in place. Chile is not a full member of Mercosur but an associated state. The economic foundation is ACE No. 35, in force since 1996 between Chile and the bloc.
According to Chile’s foreign trade authority, Chilean exports have enjoyed tariff-free access to the core Mercosur markets since 2012, without exceptions. The relationship is therefore neither loose nor symbolic. It is materially and commercially substantial. It just stops short of full institutional integration.
The Economic Complementation Agreement between Chile and Mercosur has been in force since 1996. It grants Chilean exporters tariff-free access to Argentina, Brazil, Uruguay and Paraguay — fully phased in since 2012.
Associated-state status allows Chile to participate in Mercosur summits on topics of common interest without being bound by the bloc’s common external tariff or internal decision-making structures.
A Deliberate Architecture
That is precisely where the strategic interest lies.
Chile is close enough to Mercosur to benefit from regional market opening, geographic proximity and political coordination. At the same time, it remains free to develop its global trade architecture on its own terms.
This logic was visible again at the end of 2024, when Chile and Mercosur agreed to modernise the rules-of-origin regime under ACE No. 35 — updating the agreement to reflect contemporary trade realities rather than merely administering it.
In parallel, Chile attended the LXV Summit of Heads of State and Associated States of Mercosur in Montevideo in December 2024. The signal is consistent: Santiago keeps Mercosur close without allowing itself to be absorbed by it.
"Chile keeps Mercosur close without allowing itself to be absorbed by it."
The Balance Function
Understanding Chile’s position requires looking beyond South America.
Mercosur matters to Santiago — but not because it sits at the centre of Chile’s trade strategy. That role it does not hold.
China is today Chile’s largest trading partner; according to an official SUBREI study, 32.2 percent of Chile’s total trade was with China in 2024. The United States remains a major economic pole, with bilateral goods trade reaching 38.1 billion dollars in 2025.
Chile operates in a trade geography where Asia and North America are structurally at least as important as the immediate region.
"The deeper Chile is embedded in global trade relationships, the more valuable a stable regional anchor becomes."
That is precisely why Mercosur takes on a different function for Chile. It is not the stage on which Chile builds its entire trade future. It is a regional anchor within a trade strategy otherwise shaped by larger global relationships.
Mercosur is not an alternative to China or the United States. It is the counterweight that keeps the balance.
Chile simultaneously maintains its broad network architecture — from its relationship with the European Union to its Asian connections — rather than locking itself into a single regional bloc logic.
Chile’s Mercosur position is a balancing instrument.
It gives Santiago regional anchorage without weakening the external trade flexibility that defines Chile’s broader economic model.
What Chile Represents for the Bloc
For Mercosur, Chile is also more than a peripheral partner.
Chile embodies a different integration model from the bloc’s full members. It combines regional cooperation with high international mobility, demonstrating that South American engagement does not necessarily mean institutional merger.
That is what makes Chile interesting from a regional perspective: not as a candidate for full accession at any cost, but as an example of a functional, selective and durable form of integration.
From Santiago’s perspective, there is a strong case for holding to this model. Full membership would raise the symbolic weight of South American commitment but could cost flexibility — precisely the flexibility that has become the hallmark of Chilean trade policy.
Chile’s Model: Close Enough, Free Enough
The existing formula reads clearly: close enough to remain regionally relevant; free enough to remain globally effective.
Chile’s relationship with Mercosur is not a tentative rapprochement. It is a calibrated position in a world where economic dependencies and geopolitical weights are being redistributed.
This is not hesitation. It is the consequence of a trade architecture that Chile has built deliberately over three decades.

From regional proximity to trade-strategy reality
Chile’s Mercosur position is best understood as controlled proximity: commercial access and regional anchorage without surrendering the trade-policy flexibility that connects Chile to Asia, North America and Europe.
