For a good sense of what development in Africa today is and isn't, you can do worse than to read this excellent if troubling New York Times article on Chinese business practices in Zambia:
As in many other African nations, the Chinese are an enormous economic presence in this impoverished but mineral-rich country.... Chinese investment here amounted to $1.2 billion in just the past year, according to the government. Nearly two-thirds of new construction involves Chinese-run companies, said Li Qiangmin, the Chinese ambassador in Lusaka, the capital. In this nation of 12 million where a small minority of workers, perhaps one in 10, have salaried employment, the 25,000 jobs provided by Chinese-backed businesses and projects are badly needed.You see here the direct backlash against "thin" forms of extraction, in contrast to the "thicker" forms of development that existed in the past.
But many Zambians complain that these powerful foreigners are permitted to play by their own rules, plundering the country more than developing it and abusing workers as they go.
The standard early postcolonial relationship of extraction was that the foreign investors got the minerals and/or cheap labor, and the locals got "development" in return, the latter understood as the building of institutions and infrastructure that would direct the nation-state as a whole toward eventual attainment of a liberal welfare state. This noble idea was of course more honored in the breach than in the observance, but nonetheless, it was a deal that made a certain kind of sense - both sides were clearly supposed to be getting something worthwhile out of the relationship. This arrangement, this ideological ideal, is what I refer to as "modernist" developmentalism - that is, it was a form of development that aimed at creating replicas of the modernist ideal-type limned by the New Deal-ish United States.
That vision of development is long gone, killed by decades of secular economic decline, and officially buried by structural adjustment programs promoted by the neoliberals at the IMF and the Bank. (For more on this historical shift, consult James Ferguson's or Achille Mbembe's work.)
What replaced the classic postcolonial development discourse is what I would call a "post-modernist" form of developmental practice of the sort sketched in the New York Times article quoted above: we still have a foreign power - a Chinese state-controlled company, in this case - extracting minerals, but there is no longer any pretense about providing a wider, deeper, "thicker" kind of development that benefits the Zambian people and nation as a whole. On the contrary, with the Chinese bringing in their own labor and their own technology, their impact on the local economy is more or less ring-fenced around the mine head. And while the Chinese like to present this form of investment as a sign of their respect for the "sovereignty" of the local peoples, it's not at all clear what the local (in this case) Zambians get out of this sort of deal. Hence the backlash.
