Obama says not threatened by China's focus in Africa, welcomes investment there by others

PRETORIA, South Africa — President Barack Obama says he doesn't feel threatened by the fact that other countries, led by China, are investing in Africa. In fact, Obama says the more countries that come to Africa, the merrier.

Obama says he's touring three African nations this week because the United States needs to increase its engagement with a continent that's showing promise and possibility.

He says such interaction is good for the U.S. regardless of what other countries do.

But he cautions that Africa must be wary of outside investment and always ask how it will benefit when other countries come seeking its natural resources or to make other investments.
