The Trump administration's Section 301 China tariffs of 2018-2019, imposed by USTR under the Trade Act of 1974 in response to the March 2018 unreasonable-IP-practices finding, applied 25% tariffs in successive lists totalling roughly USD 350 billion in China-source imports. Phase One trade deal of 15 January 2020 paused further escalation in exchange for Chinese commitments to USD 200 billion in additional purchases of US goods and services through 2021. The intended effect was to coerce structural Chinese economic policy changes, redress the bilateral trade imbalance, and reinforce the broader Trump first-term reorientation of US-China economic relations.
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.
