"Countries from all over the world are talking to us. Tough but fair parameters are being set," Trump wrote on the Truth Social platform.

Rather than backtracking in the face of economic turbulence on Monday, Trump doubled down by threatening China with a further 50% tariff, on top of the 34% announced recently, which had taken the level to 54%.
Writing on Truth Social, he fumed: “Yesterday, China issued Retaliatory Tariffs of 34%, on top of their already record setting Tariffs....
“Therefore, if China does not withdraw its 34% increase above their already long term trading abuses by tomorrow, April 8th, 2025, the United States will impose ADDITIONAL Tariffs on China of 50%, effective April 9th.”
A senior White House official told ABC News that this would be in addition to the 34% reciprocal tariff Trump announced last week and the 20% already in place, making for a potential total of 104%.

Investors and political leaders have struggled to determine whether Trump’s tariffs are part of a permanent new regime or a negotiating tactic to win concessions from other countries.
Investors, however, are not hanging around, as they raced to limit their losses.
JPMorgan economists now estimate the tariffs will see full-year US gross domestic product (GDP) decline by 0.3%, down from an earlier estimate of 1.3% growth.
