U.S. state attorneys general are launching investigations and lawsuits against Chinese tech firms—including networking-equipment companies—on consumer protection grounds, alleging data harvesting, privacy violations, and hidden ties to the Chinese Communist Party. These actions reflect growing domestic concern over Chinese tech’s influence on American consumers and national security, dovetailing with federal moves to restrict Chinese devices from U.S. infrastructure. The efforts illustrate a broader strategy by state-level officials to challenge Beijing-linked companies on privacy and safety issues, expanding pressure beyond traditional trade and export controls into regulatory enforcement on consumer-facing products. At the same time, similar federal actions—such as bans on Chinese-made surveillance cameras and telecom equipment—underscore a multipronged effort across government levels to limit Chinese technology’s reach in the U.S.
