Good question. I think these guys are prepared for engagement for the long haul. The Kiswahili speaking world Tanzania, Kenya, Uganda, Burundi, Eastern Congo, Northern Mozambique and Northern Malawi is mostly jungle. It is full of resources the Chinese will need, Minerals maybe even Arable land and it could benefit from Chinese infrastructure, roads, bridges, railways, cities etc. I am concerned that when they start pouring in they will not just come to get the job done and leave but they will be coming to stay.

This is an excerpt from Amy Chua's book "World on Fire". Amy Chua is of Filipino Chinese ancestry and is a professor at Yale:

My family is part of the Philippines’ tiny but economically powerful Chinese minority. Although they constitute 1 per cent of the population, Chinese Filipinos control about 60 per cent of the private economy, including the country’s four airlines and almost all of the banks, hotels, shopping malls, and big conglomerates. My own family runs a plastics conglomerate and owns swathes of prime real estate – and they are only “third-tier” Chinese tycoons. They also have safe deposit boxes full of gold bars, each one the size of a chocolate bar. I myself have such a gold bar.

In the Philippines, millions of Filipinos work for Chinese; almost no Chinese work for Filipinos. The Chinese dominate industry and commerce at every level of society. Global markets intensify this dominance: When foreign investors do business in the Philippines, they deal almost exclusively with Chinese.
