Washington Post: The Chinese government has appealed to the World Trade Organization regarding US tariffs on Chinese solar panels and other products. The US claims that Chinese companies subsidize their products, which gives them an edge over their American competitors. The Chinese counter that only government agencies can grant subsidies. But the disagreement does not appear to be an all-out trade war. The products in question account for only some $7.29 billion, just a small fraction of the trade between the two countries.
