Chinese naval base in Africa a threat to US

"The head of US Africa Command, General Michael Langley, has insisted that China cannot
be allowed open a naval base in the west of the continent. 

China established its first overseas naval base in 2017, opening a facility in the east African nation of Djibouti. US officials have since claimed that Beijing is planning similar bases in 14 countries, including two – Equatorial Guinea and Angola – on Africa’s west coast." RT
