Nigeria has criticised Washington for failing to help protect the country’s oil assets from rebel attack, forcing it to turn to other military suppliers, including China, for support.
Atiku Abubakar, Nigeria’s vice-president, told the Financial Times the US had been too slow to help protect the oil-rich Niger Delta from a growing insurgency. He said talks with the US over security plans for the region did not “appear to be moving as fast as the situation is unfolding” and Nigeria was instead sourcing military equipment elsewhere.
Nigerian security sources said China was becoming one of Nigeria’s main suppliers of military hardware. They said new supplies would include dozens of patrol boats to secure the swamps and creeks that from the launching pad for rebel attacks.
