It is strange that the incident happened just after China's announcement to build a naval base in Djibouti. At the end of November, the media reported that China had signed a ten-year contract to set up its first military base in the country. The head of the US Africa Command, General David Rodriguez, told defense reporters: "They are going to build a base in Djibouti, so that will be their first military location in Africa". He added that China would use the installation as a logistics hub "to extend their reach." Djibouti's president, Ismail Omar Guelleh, confirmed months before that his country was negotiating with China about building a naval base there.
Beijing has already invested close to $10 billion in infrastructure projects – six times the gross domestic product of the country. Infrastructure may be used for logistic with neighboring South Sudan.
The US has the "Camp Lemonnier" military base in Djibouti that is used as a key facility for counterterrorism and surveillance operations in the region.
