Scott has a lot to say about the U.S. - AD/CVD (China) Appellate Body report. I'll just give some excerpts, but check out both of his posts.
From the first post:
the AB's ruling did not rule that DOC was absolutely prohibited from conducting concurrent AD and CVD investigations against China or other NMEs. All the AB said was that double counting violated WTO rules, and that DOC's "imposition of anti-dumping duties calculated on the basis of an NME methodology, concurrently with the imposition of countervailing duties on the same products, without having assessed whether double remedies arose from such concurrent duties" was WTO-inconsistent. In short, DOC ran into trouble because it didn't even try to prevent double counting in its AD/CVD investigations of Chinese imports. Thus, DOC could perfectly comply with the AB's ruling where it developed a methodology that (i) "assesses whether double remedies arose from concurrent AD/CVD duties" and, where such double remedies are indeed found, (ii) removes any instances of double counting. This, of course, is easier said than done, but there are some pretty smart folks over at DOC, and I'm confident that they could develop such a methodology if their bosses in the White House were absolutely determined to keep the AD/CVD NME process alive. China certainly could challenge this new methodology at the WTO or in US courts, but both bodies are pretty deferential to such administrative minutiae. (They're not so deferential where, such as here, DOC doesn't even try to adopt a methodology to avoid the legal problems raised.) As noted above, this approach wouldn't perfectly comply with the CIT's aggressive ruling, but, even assuming the CAFC upholds it, Congress could always intervene to make this approach legal under US law (thereby mitigating the court rulings).
And from the second:
the Appellate Body's ruling will force major changes to the United States CVD NME policy and has totally flipped-the-script (as the kids say) on the US-China negotiating dynamic. As I noted yesterday, there is no easy fix for the United States to comply with the AB's decision - there are dozens of AD/CVD determinations that will need to be re-done; USTR and the Commerce Department are going to have to do some serious legal gymnastics to develop and defend any new CVD NME methodology; and full compliance might even require an act of Congress (which should just go swimmingly). So now, China's graduation to a market economy is in both its own and the United States' interest. China would benefit by ditching the "non-market economy" stigma, and its exporters (and US consumers, natch) would benefit from the predictability of the market economy methodology for AD/CVD investigations and reviews. But the United States also will benefit by forgoing all of the pain that will inevitably accompany its WTO compliance efforts.
Put simply, United States held on to its NME negotiating stock too long, and it just crashed. It's certainly not worthless, but it'll never again be as valuable as it was last week. Never.
