President Joe Biden singled out a “growing rivalry with China” as a key challenge facing the United States, with his top diplomat describing the Asian country as “the biggest geopolitical test” of this century.

The administration rolled out its thinking in a 24-page document outlining Biden’s national security policies along with the first major foreign policy speech by Secretary of State Antony Blinken.

“It is the only competitor potentially capable of combining its economic, diplomatic, military, and technological power to mount a sustained challenge to a stable and open international system”, - the national security document said of China.

It added that in the face of challenges from China and Russia, the U.S. military would shift its emphasis away from “unneeded legacy platforms and weapons systems to free up resources for investments” in cutting-edge technologies.
