Trade policy openness — tariffs, non-tariff barriers, FTAs, industrial protection.
Iran became a full BRICS member on 1 Jan 2024, part of the expansion announced at the Johannesburg II summit Aug 2023 (alongside Egypt, UAE, Ethiopia; Saudi Arabia and Argentina invited but did not accede). Accompanied by Shanghai Cooperation Organisation full membership Jul 2023. Strategic rationale: diversify trade and financial settlement channels away from USD-dominated systems under maximum- pressure sanctions, deepen alignment with China and Russia, and signal non-isolation. Practical trade effects modest through 2024-2025 given continuing US secondary-sanctions exposure for BRICS counterparties and the absence of a BRICS-wide alternative clearing system.
Per invariant 3, reforms are scored by what they did on each channel-separated axis, not by the party that enacted them. This fingerprint is how the policy-match engine finds historical analogues.
Explicit links are curated by the author. Inferred links are hypotheses in the library that test the same axes this policy moved — the framework's answer to "what does the data say about a policy like this?".
Ranked by axis-fingerprint overlap with this policy. Direction match bolded — those are the closest historical analogues. Shape of the match is what drives policy-outcome comparison, not the country or party label.
