“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,” Mr. Trump said in a Truth Social post. He did not elaborate, nor did he say what BRICS policies he was referring to.

Trump had previously threatened tariffs on the BRICS group if they followed through with plans to challenge the supremacy of the U.S. dollar.

The EU will delay its plan to hit the US with tariffs on €21bn of its annual exports to Europe on Tuesday in the hope of coming to an agreement after Donald Trump announced that he would hit the bloc with 30 per cent tariffs from August 1.
