As previously covered in the blog (link), the WTO issued a ruling in the Solar Panel War. The verdict is that the US improperly imposed tariffs on Chinese steel and solar panels (link). The US had argued it had to impose tariffs to combat artificially low prices on products from India and China's state-subsidised industries. Dont hold your breath. The Solar Panel War is not over since the US can still appeal.
