On March 3, Donald Trump declared his intention to adjust existing trade agreements to better favor the United States, during a discussion with German Chancellor Friedrich Merz at the White House. This shift is perceived as a move to apply maximum pressure on nations such as South Korea, Japan, and the EU, rather than simply raising stated tariff rates. Trump's statement suggests that he intends to employ his presidential powers under Trade Law Section 301 and Trade Expansion Act Section 232 to maintain the framework of existing agreements while increasing tariff rates.

The Trump administration has set a timeline for implementing these changes, with USTR representative Jamison Greer confirming that an investigation under Trade Law Section 301 will be completed within five months. During this period, Trump has enacted a global 10% tariff on all imports, initiated temporarily following a Supreme Court ruling. Once these five months expire, a transition to differentiated tariffs based on the findings of these investigations is planned, with Trump stating the intention to present different tariff structures for various countries.

Trump's rhetoric also hinted at extreme measures, including potentially halting trade with non-compliant countries. He underscored the challenging nature of negotiations, emphasizing the need for compliance and collaboration, particularly in light of Spain's, described by him as very uncooperative, stance. This declaration underscores ongoing tensions in international trade relations and could significantly impact global markets, depending on the administration's approach to tariff adjustments and diplomatic negotiations.
