#TrumpTariffs US President Donald Trump has warned that countries which side with the policies of the Brics alliance that go against US interests will be hit with an extra 10% tariff.

"Any country aligning themselves with the Anti-American policies of BRICS, will be charged an ADDITIONAL 10% tariff. There will be no exceptions to this policy," Trump wrote on social media.

Trump has long criticised Brics, an organisation whose members include China, Russia and India.

The US had set a 9 July deadline for countries to agree a trade deal, but US officials now say tariffs will begin on 1 August. Trump said he would send letters to countries telling them what the tariff rate will be if an agreement is not reached.

On Monday, Treasury Secretary Scott Bessent said he expected "a busy couple of days".

"We've had a lot of people change their tune in terms of negotiations. So my mailbox was full last night with a lot of new offers, a lot of new proposals," he told CNBC.

So far, the US has only struck trade agreements with the UK and Vietnam, as well as a partial deal with China.

Although, Britain and America have still not reached a deal over taxes for UK steel imported by the US.

Since taking office this year, Trump has announced a series of import tariffs on goods from other countries, arguing they will boost American manufacturing and protect jobs.

In April, on what he called "Liberation Day", he announced a wave of new taxes on goods from countries around the world - with some as high as 50% - although he quickly suspended his most aggressive plans to allow for three months of talks up until 9 July.

During this period, the US implemented a 10% tariff on goods entering the States from most of its international trading partners.

The European Union (EU) is reportedly in talks to keep a provisional 10% tax in place for most goods shipped to the US beyond the deadline.
