The latest case involves a practice called zeroing, a mathematical trick with pernicious economic consequences.
The United States has lost numerous cases at the World Trade Organization in the past decade over a practice called "zeroing" used to calculate anti-dumping duties on products it says are being sold in the United States at less than fair value.
The department adopted its approach after the World Trade Organization said an earlier U.S. methodology, known as "zeroing," violated global trade regulations.
If the United States really wanted to make progress in the talks, it could address a number of contentious issues, he said. cotton, from $15 billion, cut "tariff peaks" on sensitive goods that keep out, comply with WTO rulings condemning its controversial method of calculating anti-dumping duties, known as zeroing, and let in more temporary workers for services from health to construction.
But the US wants to have its way against everyone else in the so-called zeroing mechanism.
