Donald Trump has been accused of inadvertently drawing BRICS nations — a loose grouping of some of the world's fastest-growing emerging economies — closer together by imposing higher tariffs on them than on other countries.

The BRICS' largest member, China, still faces the prospect of a 145% tariff if it can't cut a deal with Trump, while Brazil and India have been slapped with a 50% rate — half of India's penalty is for buying discounted Russian oil. South Africa was given a 30% levy and even newer members like Egypt could see their tariffs go up, due to their participation in BRICS.
