Which countries will counter tariff the US in April?

This market will resolve to "Yes" if the listed country imposes any new or increased tariffs on the United States between April 4, 5:30 PM ET, and April 30, 2025, 11:59 PM ET. Otherwise, this market will resolve to “No”. Any tariff which is officially enacted within the market's time frame will qualify, regardless of when the tariff goes into effect. Only tariffs specifically targeting the U.S. will qualify. For example, a global tariff (tariffs on all imports into the listed country) will not count toward this market's resolution. This market's primary resolution source will be official information from the listed country, however a consensus of credible reporting will also be used.
