The U.S. asked China to do this during the trade negotiations:
China immediately will cease providing market-distorting subsidies and other types of government support that can contribute to the creation or maintenance of excess capacity in the industries targeted by the Made in China 2025 industrial plan;
However, why does the U.S. think it's unfair? And also what would constitute fair subsidies since the U.S. is known to give massive subsidies to companies like Boeing and Ford? Is it me or were logic and fairness thrown completely out of the window during the U.S. trade negotiations?
