"Because all tariffs ultimately show up as a tax on US consumers, they will increase the cost of Apple products that our customers have come to rely on in their daily lives," the company said in a letter to the Office of the United States Trade Representative.It added: “The burden of the proposed tariffs will fall much more heavily on the United States than on China.”But Mr Trump responded by saying: “Apple prices may increase because of the massive Tariffs we may be imposing on China – but there is an easy solution where there would be ZERO tax, and indeed a tax incentive. Make your products in the United States instead of China.”

Apple – which became the world’s first $1 trillion company last month – is highly exposed to a trade war between the two countries on two fronts.

Because it makes many products for the US market in China, it would be hit by American tariffs. But, because it also sells its gadgets in China, it may also become a target of potential retaliation taxes.  The US is set to impose its package of $200bn in tariffs in the coming days.
