North Korea has adopted a 10-year economic development plan, vowing to invest 100 billion Dollar in key sectors such as mining and agriculture. The new economic plan also calls for the construction of thousands of kilometres of roads, the renovation of the rail network and the production of millions of tonnes of iron. The closed communist state hopes to lure 100 billion Dollar in investment over the next decade. A Chinese state company recently pumped 2 billion Dollar into establishing a free trade zone in the North.
