Intelligence Leaders: China's Theft of Trade Secrets is Unprecedented Threat

China's theft of intellectual property and trade secrets is a major threat, say intelligence leaders from the "Five Eyes" nations.

The scale of China's espionage campaign is unprecedented in human history.

China steals from companies big and small, across many industries like tech, health care, agriculture.

Tactics include hacking, manipulating insiders, and acquisitions that aid espionage.

Intelligence leaders aim to work with tech companies to protect intellectual property.
