This event represents routine trade policy positioning ahead of negotiations. While tariffs involve executive authority and have economic impacts (capture:2 for economic policy influence, rule_of_law:1 and separation:1 for executive trade powers), this is standard presidential authority under existing trade law frameworks. The A-score of 6.46 falls well below the 25 threshold. The B-score of 22.28 reflects moderate media attention around trade tensions and China meeting timing, but lacks the viral characteristics for List B classification. Critically, this is a statement of unwillingness to act rather than actual policy change - it's a negotiating position announcement. No constitutional mechanism is being stretched or damaged; this falls squarely within established executive trade authority. The timing before the China meeting suggests strategic communication rather than substantive constitutional event.
