Anecdotes & Data
It's widely believed that Chinese companies refuse to hire Africans and bring in all their own workers. The real story is more complicated. I've not yet seen a case of a Chinese company in Africa hiring no local workers at all, but the percentage of Chinese and Africans varies widely. Many factors affect this: local labor laws, the work permit regime, enforcement of work permits, the availability of skilled labor and its cost. In Angola, for example, emerging from decades of civil war, skilled and literate workers are scarce and expensive. Here, Chinese firms find it pays to import workers from China.
In this note, I propose to collect information -- where it exists -- about the proportion of Chinese and Africans working on any given project, and the extent to which African managers and skilled labor are present.

Ongoing. Dozens of the more recent China Eximbank financed projects listed at the Angolan Ministry of Finance website give information about Chinese versus Angolan workers, project by project. My calculations from this source, as of 2010, show an average ratio of 54 Angolans to 46 Chinese over 19 separate infrastructure projects. Source: Ministry of Finance, Angola

The next set of information all comes from a survey of nine major Chinese companies in Rwanda done by a Chinese official in Rwanda, and shared with me. The numbers are as of January 2011.
China Road & Bridge Corporation (CRBC) came Rwanda in 1974 (only left for 3 months in 1994), built 70% of the roads here. At moment, they have 110 Chinese and 2,000 local workers here.
China Geo-Engineering Co. (CGEC) came 2000 for water/electricity supply projects. They have 110 Chinese and 800-4,000 local workers depending on differiate time and phases of projects.
China Civil Engineering Co. (CCECC) built a sports stadium late 1980s, and came back only in 2004, now building housing here with 50 Chinese and 300 locals.
Huawei is maintaining its project handed over in 2007 with 30 Chinese and 17 local technicians.

2013. Survey by China Africa Business Council of 193 member companies in Africa found 34,000 local employees and 6,400 Chinese workers, or an average ratio of 2 Chinese workers to every 10 African workers.
2013. Equatorial Guinea Enrique Martino reports: no local EG laborers at all. 90% of the laborers are Chinese, and 10% come from Mali or Cameroon. (DB: this is consistent with what I have seen in the official data. In 2008, there were officially 3782 Chinese sent to EG for labor. This was the fourth highest number in Africa, coming behind Algeria, Sudan, and Angola. It probably reflects the small size of the population in EG, only 700,000 people, and the lack of skilled workers with construction experience.
