CHINA, RUSSIA BIGGEST THREATS, REPORT SAYS

China's push for global power is the leading threat to U.S. national security, while Russia's efforts to undermine American influence and assert itself as a major actor also pose a challenge, said a U.S. intelligence report released on Tuesday.

The 2021 Annual Threat Assessment lays out U.S. spy agencies' views of the chief foreign policy issues facing U.S. President Joe Biden, complicated by the coronavirus pandemic and climate change.

While China and Russia are presented as the top challenges, Iran and North Korea will also test U.S. national security, the report said.

The report also said the Chinese Communist Party will press “whole-of-government efforts to spread China's influence, undercut that of the United States, drive wedges between Washington and its allies.”
