The result indicates that China＇s product-specific amber box support level has significantly increased but not yet exceeded the tolerable ceiling of de minimis and remains consistent with WTO rules on agricultural domestic support,＂ that there is still policy room for product-specific amber box support but the ceiling of de minimis has already imposed substantial constraint on China＇s grain price support policies; and that despite rapid increases in non-product-specific amber box support levels, future policy space remains significant. The result also suggests that China should make appropriate adjustments to product-specific amber box support policies in accordance with WTO rules on agricultural domestic support and make proper use of non- product-specific amber box support policies.展开更多
