By the end of 2017, the People's Republic of China (PRC) had the world's largest number of internet users, estimated at over 750 million people. At the same time, the country has one of the most sophisticated and aggressive internet censorship and control regimes in the world. PRC officials have argued that internet controls are necessary for social stability, and are intended to "enhance people's cultural taste" and "strengthen spiritual civilization." The PRC government employs a variety of methods to control online content and expression, including website blocking and keyword filtering; regulating and monitoring internet service providers; censoring social media; and arresting "cyber dissidents" and bloggers who broach sensitive social or political issues. The government also monitors the popular mobile app WeChat. WeChat began as a secure messaging app, similar to WhatsApp, but it is now used for much more than just messaging and calling (e.g., mobile payments)—and all the data shared through the app is also shared with the Chinese government. During the 2017 Communist Party Congress, censors took steps to "restrict with one hand and disseminate with the other." Censors using a variety of tools sought to eliminate certain words and expressions from appearing on social media (e.g., attempts to protest or ridicule senior political figures), while disseminating information supportive of the government and its leaders. In its 2017 Annual Report, Reporters Without Borders (Reporters Sans Frontières, RSF) called China the "world's biggest prison for journalists" and warned that the country "continues to improve its arsenal of measures for persecuting journalists and bloggers." China ranks 176 th out of 180 countries in RSF's 2017 World Press Freedom Index, surpassed only by Turkmenistan, Eritrea, and North Korea in restrictions on press freedom. At the end of 2017, RSF asserted that China was holding 52 journalists and bloggers in prison. This report describes the current state of internet freedom in China, U.S. government and private sector activity to support internet freedom around the world, and related issues of congressional interest. The U.S. government continues to advocate policies to promote internet freedom in China's increasingly restrictive environment and to mitigate the global impact of Chinese government censorship. The Department of State, the Broadcasting Board of Governors (BBG), and Congress have taken an active role in fighting global internet censorship. Since 2008, the Department of State has invested over $145 million in global internet freedom programs. These programs support digital safety, policy advocacy, technology, and research to help global internet users overcome barriers to accessing the internet. The State Department's Internet Freedom and Business and Human Rights Section within the Bureau of Democracy, Human Rights, and Labor leads U.S. government policy and engagement on internet freedom issues. Efforts include the following: raising concerns about internet restrictions with foreign governments; collaborating with like-minded governments to advance internet freedom, including in multilateral fora such as the United Nations Human Rights Council, the G-7, and the G-20; working with interagency partners and civil society stakeholders to advance internet freedom, including at the annual Internet Governance Forum, an international multistakeholder venue for addressing global internet governance; convening discussions on emerging and critical internet freedom challenges; and building awareness within the U.S. government by conducting training on internet freedom issues for federal officials. The State Department was also a founding member and is an ongoing participant in the Freedom Online Coalition (FOC), a group of governments collaborating to advance human rights online. Examples of FOC work include building cross-regional support for internet freedom language in key international documents and joint statements on issues of concern to help shape global norms on human rights online. The Digital Defenders Partnership is a project of the Freedom Online Coalition. The partnership, established in 2012, provides emergency support for internet users who are under threat for peacefully exercising their rights online. It awards grants around the world for a number of purposes, including establishing new internet connections when existing connections have been cut off or are being restricted; developing methods to protect bloggers and digital activists; developing tools needed to respond to emergencies; developing decentralized, mobile internet applications that can link computers as an independent network; supporting digital activists with secure hosting and distributed denial of service mitigation; and building emergency response capacity. In 2016, the BBG created the Office of Internet Freedom (OIF) to oversee the efforts of BBG-funded internet freedom projects, including the work carried out by the Open Technology Fund, a joint endeavor managed by BBG and Radio Free Asia. OIF manages and supports the research, development, deployment, and use of BBG-funded internet freedom (IF) technologies. OIF provides anticensorship technologies and services to citizens and journalists living in repressive environments. OIF also supports global education and awareness of IF matters, to enhance users' ability to safely access and share digital news and information without fear of repressive censorship or surveillance. The FY2018 budget for the OIF is included in the State Department's appropriation for satellite transmissions. The Consolidated Appropriations Act, 2018, provides that "in addition to amounts otherwise available for such purposes, up to $34,508,000 of the amount appropriated under this heading may remain available until expended for satellite transmissions and internet freedom programs, of which not less than $13,800,000 shall be for internet freedom programs." Internet freedom programs are also funded through grants by the Open Technology Fund. There has been one hearing in the 115 th Congress about Internet Freedom in China by the Congressional-Executive Commission on China (CECC). In 2000, Congress created the CECC to monitor China's compliance with international human rights standards, to encourage the development of the rule of law in the PRC, and to establish and maintain a list of victims of human rights abuses in China. On April 26, 2018, the CECC held a hearing on "digital authoritarianism and the global threat to free speech." The Commission heard from three witnesses about aspects of China's restrictions to free speech: Sarah Cook Senior Research Analyst for East Asia and Editor, China Media Bulletin, Freedom House Clive Hamilton Professor of Public Ethics, Charles Sturt University, Canberra, Australia, and author, Silent Invasion, China 's Influence in Australia Katrina Lantos Swett President, Lantos Foundation The hearing explored issues such as China's desire to control the internet, such as through the shutdown of popular social media apps that do not meet the country's standards of "core socialist values." The hearing also examined U.S. policies promoting internet freedom and firewall circumvention, and the global impact of Chinese government censorship and efforts to "export" its system and values. No legislation has been introduced in the 115 th Congress related to global internet freedom in authoritarian regimes. In response to criticism, particularly of their operations in China, a group of U.S. information and communications technology (ICT) companies, along with nongovernmental organizations, investors, and universities, formed the Global Network Initiative (GNI) in 2008. The GNI aims to promote best practices related to the conduct of U.S. companies in countries with poor internet freedom records. The GNI uses a self-regulatory approach to promote due diligence and awareness regarding human rights. For example, GNI has adopted a set of principles and supporting mechanisms to provide guidance to the ICT industry and its stakeholders on how to protect and advance freedom of expression and the right to privacy when faced with pressures from governments to take actions that infringe upon these rights. Participating companies voluntarily agree to undergo third-party assessments of their compliance with GNI principles. While some human rights groups have criticized the GNI's guidelines for being weak or too broad, GNI's supporters argue that the initiative sets realistic goals and creates real incentives for companies to uphold free expression and privacy. In May 2018, the GNI continued its participation in RightsCon, a yearly summit that explores issues affecting free expression and protection of global journalism, gender diversity and digital inclusion, encryption and cybersecurity, and other topics related to internet freedom. For many years, the development of the internet and its use in China have raised U.S. congressional concerns, including those related to human rights, trade and investment, and cybersecurity. Congressional interest in the internet in China has been tied to human rights concerns in a number of ways, including the use of the internet as a U.S. tool for promoting freedom of expression and other rights in China; the use of the internet by political dissidents in the PRC, and the political repression that such use often provokes; and the role of U.S. internet companies in both spreading freedom in China and complying with or enhancing PRC censorship and social control efforts. Congress has funded a variety of activities to support global internet freedom, including censorship circumvention technology development, internet and mobile communications security training, media and advocacy skills, and public policy. China and Iran have been the primary targets of such efforts, particularly circumvention and secure communications programs. In past years, U.S. congressional committees and commissions have held hearings on the internet and China, including the roles of U.S. internet companies in China's censorship regime, cybersecurity, free trade in internet services, and the protection of intellectual property rights.
