From a letter to President Bush from the House Ways and Means Committee:
The Appendix to this letter contains a compilation of a number of the most persistent barriers to trade, and proposed causes of action to address each. These matters are long overdue for effective action by the Administration. We strongly encourage you to instruct USTR to request immediate consultations with the following key trading partners: Canada, China, the European Union, Japan, Korea, Mexico, Russia, and the United Kingdom. If these significant trade issues cannot be resolved within the consultation period, we urge USTR to take appropriate action, whether under WTO rules, U.S. law, in bilateral negotiations, or a combination of these approaches. These trade barriers affect the manufacturing, services and agriculture sectors of our economy, and many involve the violation of intellectual property rights (IPR).
Here is the press release.
