US President Donald Trump doubled tariffs on Indian goods to 50% as a penalty for its purchases of Russian oil, escalating a fight with a key Asian partner and sparking outrage in New Delhi.

In tech: Trump and Tim Cook, Apple’s chief executive, announced that the company was pledging $100 billion in additional U.S. investment, its latest move to avoid iPhone tariffs. Trump also threatened to impose levies of 100 percent on all foreign-made chips next week unless manufacturers agreed to invest and build in the U.S.

India, which now faces among the highest tariff rates imposed by the US, called the levy "unjustified and unreasonable".
