The loan will have a maturity of 9.5 years.
The transaction comes under the state-owned South Korean bank's program of providing export credit and guarantee programs to support Korean exporters.
In January, Nigeria LNG, a leading liquefied natural gas exporter, signed a contract with two South Korean shipyards -- Samsung Heavy Industries Co. and Hyundai Heavy Industries Co. -- for six LNG vessels worth $1.3 billion, Yonhap News reported.
The South Korean bank said an additional $360 million in loans will come jointly from Korea's state-run trade insurance firm K-sure and Korea Finance Corp.
The announcement said the loans would allow Korean exporters to win more deals in Africa.
