China says U.S. policies are causing existential damage to the WTO

China said on Monday U.S. policies are threatening the existence of the World Trade Organization, setting out a string of grievances in a WTO "reform proposal" published by the WTO on its website.Since entering office, Trump has taken a tough line on the WTO, accusing it of unfairly penalising U.S. trade while being soft on China, which was a far smaller economy when it joined the WTO in 2001.
