I have no special love for the Chinese, but Algeria has been a violence-wracked hellhole for at least 50 years. It’s an Arab and Berber country; definitely not black Africa. Natural resource exploitation is done by French companies with state connections who pay off the Algerian authorities.
Algeria has been in trouble domestically for a long time. They ended up exporting sizable share of it abroad. Now, troubles came to Algeria, in the form of Chinese migrants. Algeria is now in a bigger trouble. Especially when and if local Al Qaeda ally gets active using Xinjiang incident as a pretext.
