By Philip Blenkinsop, David Lawder and Stephanie van den Berg BRUSSELS/BANFF, Canada/THE HAGUE (Reuters) -U.S. President Donald Trump threatened on Friday to ratchet up his trade war again, pushing for a 50% tariff on European Union goods starting June 1 and warning Apple he may slap a 25% levy on all imported iPhones bought by U.

Apple looks to be doubling down on its manufacturing plans in India, despite Donald Trump’s demands that the company reshore its production facilities to the US.

Apple has become a frequent target for Trump, a factor that has held the stock back as other big tech companies have rebounded over the past month.

The Trump administration is escalating its battle with Harvard University, blocking the university from enrolling international students. More than 6,700 currently enrolled foreign students would need to transfer or lose their legal status.
