China’s Commerce Ministry said that it has launched a complaint at the WTO against the US over tariffs. No details were released regarding the case, but MOFCOM just said the tariffs affected USD 300B of Chinese exports. It also said the latest tariff actions violated the consensus reached by presidents of both countries at G20 in Osaka.
Under WTO rules, the US will have 60 days to try to settle the dispute. Afterwards, China could WTO to adjudicate. If US is found to have broken rules, China would get approvals for trade sanctions. But even so, the process could take several years.
