FBI Director Christopher Wray said the Chinese Communist Party is engaged in a “whole-of-state effort” to supplant the global dominance of the United States and to become the world’s sole superpower “by any means necessary.”

Wray, who has often spoken about the dangers posed by Beijing’s foreign influence as the Trump administration has stepped up its rhetoric and its actions against the Chinese government, issued his strongest warnings yet about the threat to the U.S. posed by China’s actions worldwide during an event hosted by the Hudson Institute on Tuesday.
