There are still immense problems with infrastructure in Afghanistan, more roads and railways are needed if large scale investment by China and others is to be made a success. There is little point in huge investment in mines if the product of those mines then can’t be transported out of the country to the markets as a result of either poor infrastructure or security concerns. There are also cases where infrastructure built by the US military has been allowed to deteriorate when handed over to Afghan control; there have been problems maintaining almost half the infrastructure projects built by the US in Laghman province.
