For those of you looking for background on the China specific safeguard, check out the following:
-- The China Accession Protocol, at Section 16, "Transitional Product-Specific Safeguard Mechanism", for the full text.
-- The following articles, which I have not read but look like they would be useful (two of them are available online):
Yong-Shik Lee, "The Specific Safeguard Mechanism in the Protocol on China’s Accession to the WTO: A Serious Step Backward from the Achievement of the Uruguay Round," 5 J. WORLD INTEL. PROP. 219, 227 (2002).
