Here an excerpt:
The US claims that such impressive feats have been achieved in part by the establishment of a green fund that helps firms make wind power equipment, with the stipulation that some parts be sourced from Chinese firms. If the WTO finds that China’s green fund targets only specific sectors, that such funds are conditioned on sourcing to local firms, and that the funds are channelled to trade activities that harm US firms and workers, then China may indeed be found in violation of the WTO rules.
But if that does prove to be the case, China should not be seen as the problem. The problem is the WTO.
