US President Donald Trump said he will start sending letters to different countries on Monday, warning them about new tariffs (extra taxes on imports). Trump plans to send up to 15 letters, telling countries that if they don’t make trade deals with the US soon, he will bring back the higher tariffs he announced in April. However, US Treasury Secretary Scott Bessent said these higher tariffs won’t start until August 1, so countries still have some time to make deals. Trump shared this news on his social media platform, Truth Social, and said the letters will be sent starting Monday at 12 p.m. Eastern time.

Later, he also threatened an extra 10% tariff on countries supporting BRICS (a group of emerging economies), accusing them of being against the US. On April 2, Trump announced new tariffs (extra taxes on goods coming into the US), and a 10% tax on imports from almost all countries. He called this day "Liberation Day." Some countries, like some in Europe, were going to face even higher taxes.

When markets started falling because of this news, Trump decided to pause these tariffs for 90 days so there could be trade talks. This pause will end on Wednesday. So far, only a few deals have been made, with Britain and Vietnam. The US and China also agreed to temporarily lower some of their high tariffs on each other’s products.
Trump said he plans to send 12 to 15 warning letters to countries on Monday, telling them to make trade deals or face higher tariffs. He said he thinks most countries will either get a letter or finish a deal by July 9.

US officials confirmed the new tariffs will start on August 1. They said this is not a new deadline, but simply the date when the higher taxes will begin. The goal, they said, is to put “maximum pressure” on countries to make deals quickly. Some countries, like those in the European Union, are making progress in talks. France also said it hopes to reach a deal soon. However, some countries are still worried.

Japan’s Prime Minister said he won’t give in easily. Leaders from the BRICS group (countries like Brazil, Russia, India, China, and others) also criticized Trump’s tariffs, saying they are unfair and bad for global trade. In response, Trump said any country that supports BRICS’ “anti-American” ideas will face an extra 10% tariff, with no exceptions.
