Nicholas Yong , BBC News; Industrial espionage: How China sneaks out America's technology secrets
"It is part of a broader struggle as China strives to gain technological knowhow to power its economy and its challenge to the geopolitical order, while the US does its best to prevent a serious competitor to American power from emerging.
The theft of trade secrets is attractive because it allows countries to "leapfrog up global value chains relatively quickly - and without the costs, both in terms of time and money, of relying completely on indigenous capabilities", Nick Marro of the Economist Intelligence Unit told the BBC.
Last July FBI director Christopher Wray told a gathering of business leaders and academics in London that China aimed to "ransack" the intellectual property of Western companies so it can speed up its own industrial development and eventually dominate key industries.
He warned that it was snooping on companies everywhere "from big cities to small towns - from Fortune 100s to start-ups, folks that focus on everything from aviation, to AI, to pharma"."
