Ah yes, Dr Dumbdumb spewing leftist bullshit right on schedule.
"A WTO dispute panel ruled on Thursday that under the terms of its 2001 WTO accession, China's administration of the tariff rate quotas (TRQs) as a whole violated its obligation to administer them on a "transparent, predictable and fair basis"."
Obama's WTO dispute was about tariff rate quotas for all agricultural imports, not just rice.
"China opened its rice market when it joined the World Trade Organization in 2001, but a lack of phytosanitary protocol between China and the United States effectively banned imports, according to trade group USA Rice."
"As of Dec. 27, imports of brown rice, polished rice and crushed rice from the United States are now permitted, as long as cargoes meet China's inspection standards and are registered with the U.S. Department of Agriculture."
Lack of phytosanitary protocols, not tariffs. But you should never let facts get in the way of propaganda, right Joseph Goebbels Jr?
