The House Homeland Security Committee is set to reveal new details of threats to the American homeland posed by China, the panel’s chairman said Thursday.

Rep. Mark E. Green, the committee chair, said a hearing is set to examine Chinese “information warfare” activities.

“The People’s Republic of China is working tirelessly to unseat the United States as the global hegemon, using the Chinese Communist Party as its greatest weapon of global information warfare,” the Tennessee Republican lawmaker told The Washington Times.

The operations include Chinese infiltration of U.S. high education institutions, clandestine Chinese police stations in American cities, large-scale cyberespionage and subversion of critical U.S. supply chains, he said.

Mr. Green said the activities demonstrate that Beijing is casting “an authoritarian shadow” on the United States and its allies.

“As America’s greatest geopolitical adversary threatens our homeland security, I look forward to hearing from this panel of experts on how to take decisive action,” Mr. Green said.

The hearing Wednesday will include testimony from several China affairs experts and former government officials with experience on Beijing’s intelligence operations.

A subcommittee hearing earlier this month heard testimony that Chinese companies are using commercial port operations in the Western Hemisphere to project power, conduct surveillance, facilitate illicit trafficking and take steps to disrupt U.S. military logistics operations and trade routes in a future crisis or conflict.

Committee members also introduced legislation that would require the Department of Homeland Security to set up a special working group focused on Chinese threats to the United States.

Other pending legislation by panel members is seeking to restrict Department of Homeland Security funding to any universities that host Chinese government-linked Confucius Institutes — language and cultural centers that U.S. security officials say are being used by Beijing for political influence activities.

The Homeland Security Committee also published a recent report, “The China Threat Snapshot,” that disclosed over 60 Chinese espionage cases in 20 states from early 2021 to August 2024.

Mr. Green also introduced legislation last month that would impose stronger U.S. export controls to prevent China from acquiring sensitive American technology.
