Nairobe - Sierra Leone's economic growth is likely to slow to 15 percent this year from 21 percent in 2013, a top finance official said on Thursday, with growth powered by fresh foreign investment in the mining and farming industries.

Momodu Kargbo, minister of state in the West African nation's finance ministry told Reuters on the sidelines of a meeting in the Kenyan capital that the 15 percent expected growth rate would still be among the fastest in Africa.

He said the aid-dependent country was seeking a credit rating to see if it could tap international capital markets, and could secure that assessment by mid-2015.
