European and North American leaders escalated pushback Friday against President Donald Trump's latest tariff threats, framing unilateral U.S. demands on steel procurement and digital taxes as violations of existing trade agreements. The coordinated rhetoric followed Italy's cancellation of a Washington visit and preceded an emergency European Union trade ministers' call scheduled for Monday.

French President Emmanuel Macron said Europe will not negotiate under threat and will deploy countermeasures proportionate to any U.S. duties. Canadian Finance Minister spokespeople echoed the message after Ottawa received a similar notice on aluminum exports tied to defense contracts.

Policy Flashpoints

Three disputes drive the rift: specialty steel used in infrastructure, digital services taxes affecting U.S. technology platforms, and Buy American clauses in federally funded foreign projects. Trump administration officials argue allies free-ride on U.S. military spending while restricting American exporters.

Allied governments counter that WTO-compliant agreements and bilateral treaties govern procurement, and that digital levies target revenue fairness rather than discriminate by nationality.

U.S. Domestic Politics

Congressional Republicans from steel-producing states backed the administration's hard line. Senators from export-dependent agriculture states warned retaliation could hit farm shipments before harvest season. Business Roundtable members urged phased negotiations instead of August deadline ultimatums.

Market Reaction

The euro dipped 0.4 percent against the dollar while European industrial indices fell 1.2 percent. U.S. steelmakers gained on expectations of protected orders. Supply-chain analysts said automotive and aerospace firms face input cost uncertainty if alloy tariffs materialize.

Path Forward

Deputies from USTR and the European Commission resume talks June 24 in Geneva. Diplomats said a limited quota deal remains possible if both sides drop public ultimatums. Failure would trigger EU retaliation lists drafted in May and awaiting political activation.
