There is no commonly agreed single definition of “cybercrime”. It refers to illegal internet-mediated activities that often take place in global electronic networks. Cybercrime is "international" or "transnational" – there are ‘no cyber-borders between countries'. International cybercrimes often challenge the effectiveness of domestic and international law, and law enforcement. Because existing laws in many countries are not tailored to deal with cybercrime, criminals increasingly conduct crimes on the Internet in order to take advantages of the less severe punishments or difficulties of being traced. No matter, in developing or developed countries, governments and industries have gradually realized the colossal threats of cybercrime on economic and political security and public interests. However, complexity in types and forms of cybercrime increases the difficulty to fight back. In this sense, fighting cybercrime calls for international cooperation. Various organizations and governments have already made joint efforts in establishing global standards of legislation and law enforcement both on a regional and on an international scale. China–United States cooperation is one of the most striking progress recently, because they are the top two source countries of cybercrime.
