International trade rules play a large role in creating world poverty, according to Oxfam, an international confederation of organizations committed to end poverty. In a recent report, "Rigged Rules and Double Standards," the group accuses rich nations of robbing poor nations of $100 billion a year by abusing trade rules. It also criticizes pharma for enforcing its patents in poor countries.

One of the major culprits named is the World Trade Organization (WTO) and its rules on intellectual property. The report is particularly scathing in its assessment of the Trade Related Aspects of Intellectual Property Rights Agreement (TRIPs), which aims to ensure that patents are stringently enforced.

Oxfam claims that compliance with TRIPs could cost developing countries $40 billion in increased license payments, half of it to the United States. It calls TRIPs "an act of institutionalized fraud, sanctioned by WTO rules."
