<P> The Great Firewall of China ( abbreviated to GFW ) is the combination of legislative actions and technologies enforced by the People 's Republic of China to regulate the Internet domestically . Its role in the Internet censorship in China is to block access to selected foreign websites and to slow down cross-border internet traffic . The effect includes : limiting access to foreign information sources , blocking foreign internet tools ( e.g. Google search , Facebook ) and mobile apps , and requiring foreign companies to adapt to domestic regulations . Besides censorship , the GFW has also influenced the development of China 's internal internet economy by nurturing domestic companies and reducing the effectiveness of products from foreign internet companies . </P>
