While Section 301 was a powerful, unilateral U.S. trade policy weapon prior to the establishment of the WTO dispute settlement process, since 1995 it has rarely been invoked and has not produced any sanctions or WTO cases. In a post-WTO world, therefore, the USW petition could be said to be unprecedented. It is the first to be accepted by USTR that, if proven, would, invalidate for WTO purposes what amounts to a national industrial policy. It would seriously undermine the validity of China’s efforts to create “national champions” in certain sectors, to focus on building domestic capacity to address its environmental and energy challenges, and to be a significant, and possibly the dominant, global player in green technologies. Beyond the impact on China, a successful U.S. challenge in the WTO would inevitably chill similar efforts in other countries to use the Chinese industrial development template in other sectors. All of these effects are above and beyond the question of the immediate fall-out that could result if China declines to implement an adverse WTO finding and the U.S. compensation and retaliation is authorized.
