““Eric Spiegel, the head of Siemens’ US arm, laid out a vision not that far removed from Ms Huang’s when he spoke at a breakfast in Washington hosted by the McKinsey Global Institute, the consultancy’s think-tank. The German engineering company, he said, would soon begin delivering spare parts to customers via email and 3D printers, also avoiding physical borders and the usual logistical complexities of global trade.

The negotiation of a 12-country Transpacific trade partnership (TPP) has sparked debate in Australia and New Zealand over whether companies ought to be allowed to store personal banking and medical data in foreign countries, or if such sensitive information should even be allowed to cross borders freely.””
