President Donald Trump aims to prevent conflict with China over Taiwan and the South China Sea by building up U.S. and allies' military power, according to a new U.S. strategy document.

Fox News chief national security correspondent Jennifer Griffin reports on the White House’s release of its National Security Strategy and more on ‘The Story.’
