Zero tariff to Taiwanese products in violation of WTO rules

On March 16th, China announced that another 11 vegetables and 8 fishery products from Taiwan will be granted zero tariff when imported into China. I have pointed out two years ago in an interview with Asia Times that such zero tariff violates the MFN rule of the WTO. No WTO Member, however, seemed to have enough interests in these products to bring the issue up in the WTO. The new list includes shrimp, which is a major export items for several countries in Asia. There might be some complaints from them this time.
