Threats to U.S. Networks: Oversight of Chinese Government-Owned Carriers, Staff Report, Permanent Subcommittee on Investigations, United States Senate [open pdf - 1MB]
From the Executive Summary: "Information and telecommunications technologies bring the world closer together, allowing individuals and businesses nearly everywhere in the world to communicate with each other. The expansion of global telecommunications networks, in particular, acts as a driving force of economic development by affording individuals unprecedented access to information and opportunities. Understanding the increasing interconnectedness of society, the Federal Communications Commission ('FCC')--the federal agency tasked with regulating the U.S. telecommunications industry--strives to open U.S. markets to foreign telecommunications carriers, where doing so is in the country's public interest. As a result, foreign-owned carriers have established operations within the United States. Not all international expansion of telecommunications carriers, however, is in the United States' national security interests. Some foreign governments seek to exploit the openness of America's telecommunications market to advance their own national interests. One such country is China. The Chinese government views telecommunications as a 'strategic' industry. [...] This report details how the U.S. federal government--particularly the FCC, Department of Justice ('DOJ'), and Department of Homeland Security ('DHS')-- historically exercised minimal oversight to safeguard U.S. telecommunications networks against risks posed by Chinese state-owned carriers."
