The World Trade Organization’s view is that the developed countries will lose agriculture after abolishing protectionism, and thus need the developing countries to open industry/services market largely as a compensation. But the developed countries cannot afford to lose agriculture as the most strategic lifeline, and the developing countries cannot afford to open industry/services market largely since it is weak in front of the developed countries. Hence the blockade of the Doha negotiations. The author's solution - the USA and Canada (just as New Zealand and Australia demonstrated in the mid-1980s) would not need to adopt the proposed Dual Land System, but the other developed countries would need to, then substantially cutting agricultural subsidies would not lead them to lose agriculture, and thus no need to ask the developing countries to largely open non-agricultural markets as a compensation. Hence the breakthrough of the Doha negotiations.
