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.
Trump has long criticised Brics, an organisation whose members include China, Russia and India, which was designed to boost countries' international standing and challenge the US and western Europe.
"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.
A deadline for countries to agree a tariff deal with the US had been set for 9 July but US officials now say they will begin on 1 August.
So far, the US has only struck trade agreements with the UK and Vietnam. However, Britain and America have still not reached a deal over taxes for UK steel imported by the US.
Since taking office in January, Trump has announced a series of import taxes on goods from other countries - arguing they will boost American manufacturing and protect jobs.
Last year, the list of Brics members expanded beyond Brazil, Russia, India, China and South Africa to include Egypt, Ethiopia, Indonesia, Iran, Saudi Arabia and the United Arab Emirates.
The countries in the bloc account for more than half of the world's population.
