Ninetytrade deals in 90 days did not materialize early in the US President Donald Trump’s second term. "Liberation Day" in April caused panic in the financial markets. Trump has also acknowledged that bespoke trade agreements with dozens of countries are too time-consuming.

“There’s 200 countries, “You can’t talk to all of them,” he said. President reframed his plan to impose every nation in a series of unusual presidential letters to foreign leaders. The letters established new thresholds not only for trade negotiations but also for diplomatic style, tone, and delivery. Most of the letters are fill-in-the-blank forms, including the recipient's name and a specified tariff rate. Many contain capitalized words reflecting President Trump’s distinct social media style. A few include typos and formatting issues.

The letters open with a formal salutation, a grievance, the threat of a big jump in tariffs, a new deadline and an escape ramp: "We will, perhaps, consider an adjustment to this letter" if certain conditions are met. Departing from conventional diplomatic language emphasizing mutual respect, President Trump often concludes with phrases such as “Thank you for your attention to this matter!” and “Best wishes.”

Trump appears to have given attention to his letter to Canada, with which he has been engaged in ongoing disputes and public taunts for months, and to Brazil, which he singled out for 50 percent Trump’s tariffs, apparently driven by personal grievance rather than economic relation.

President indicated that receiving a letter from him should be viewed positively by foreign leaders, as it signals his willingness to engage in talks.

"A letter means a deal," he said during a Cabinet meeting. "We can't meet with 200 countries," he said.

Trump also managed to make his erratic trade policy baffling for American trading partners eager to negotiate a way to dodge his wrath. The president escalated a conflict he started with America's second-biggest trading partner and longstanding ally, raising the tariff effectively a tax on many Canadian imports to 35 percent effective August 1. Trump announced more tariffs, this time on two of the United States' biggest trade partners, theEuropean Union and Mexico, at 30 percent each.

It remains unclear whether the proposed tariffs would benefit American consumers. Trump's threat to boost import taxes by 50 percent on Brazilian goods could drive up the cost of breakfast in the US by making staples such as coffee and orange juice more expensive.Reception has been spotty. The response to the letters, which the White House says will also be mailed, has been mixed.

Canadian Prime Minister Mark Carney's office issued a mild statement acknowledging the new August 1 deadline and suggesting he would stay the course "steadfastly defending our workers and businesses."

Brazilian President Luiz Inacio Lula da Silva, meanwhile, vowed retaliatory tariffs and ordered his diplomats to return Trump's letter if it ever physically arrives at the presidential palace in Brasilia.
