Japan, which Trump said Monday faces a 25% tariff, wants concessions for its large automobile industry and will not sacrifice its agriculture sector for an early deal, top trade negotiator Ryosei Akazawa said.

Trump said he was slapping 25% tariffs on Japan and South Korea in his first letters to trading partners ahead of a deadline to reach a deal with Washington.

Trump said on Monday that the US would impose 25 per cent tariffs on Tunisia, Malaysia and Kazakhstan; 30 per cent on South Africa, Bosnia and Herzegovina; 32 per cent on Indonesia; 35 per cent on Serbia and Bangladesh; 36 per cent on Cambodia and Thailand and 40 per cent on Laos and Myanmar.
