We get analysis from Jon Swartz, who covers Silicon Valley for Barron's magazine. President Trump says trade talks with China will continue even after the US increased border tariffs on Chinese imports on Friday. Meanwhile, companies around the world are trying to work out what the new tariffs mean for them.

The founder of Amazon, Jeff Bezos, Elon Musk of Tesla and Sir Richard Branson of the UK's Virgin are all trying to become dominant commercial operations in space.
