Defense Secretary Jim Mattis on Friday said America is facing "growing threats" from China and Russia and warned that the US military's advantages have eroded in recent years.

"We face growing threats from revisionist powers as different as China and Russia, nations that seek to create a world consistent with their authoritarian models," Mattis said as he unveiled the Pentagon's national defense strategy. 

"Our military is still strong, yet our competitive edge has eroded in every domain of warfare," he added.
