Donald Trump negatively affected Mexico's economy eight times in the last year through tariff threats and measures.

Omissions

• The specific count of '8' tariff threats/measures does not appear explicitly in any source found; the available sources document at least 4-6 distinct episodes against Mexico in 2025 (February IEEPA 25% tariffs, March implementation, Section 232 steel/aluminium and auto tariffs, the 50% steel/aluminium threat of 30 May 2025), so a count of eight is plausible but not directly confirmed.
• Search results were limited (search limit reached), so a full enumeration covering later 2025 and early 2026 Mexico-specific tariff actions could not be retrieved.
• The period 'last year' was resolved to calendar 2025; the documented episodes in the sources found all fall within 2025, consistent with the claim's timeframe.
