Paraphrasing (20th paragraph)

Text

There are a number of other ways in which the WTO and NAFTA have hurt U.S. economic interests. These include the “investment ” chapters in NAFTA that have been used to overturn national laws in areas ranging from land use to environmental and safety standards. Before negotiations have even begun in a new trade round, policy makers are battling over whether U.S. agricultural subsidies conflict with present and potential future WTO trade rules on agriculture, and whether those payments must be cut in the near future.

The main idea of the paragraph

The investment chapters in NAFTA and the WTO trade rules on agriculture have also hurt U.S. economic interests.

北美自由贸易协定中有关投资的条款和世界贸易组织中有关农产品的贸易规则也损害了美国的经济利益。
