Russian Foreign Affairs Minister Sergey Lavrov has arrived in Kenya on an unannounced trip.
Moscow's Ministry of Foreign Affairs announced Mr Lavrov's arrival in Nairobi on Monday morning, without giving further details on the visit.
The Russian embassy in Nairobi in a tweet said this would be "a very fruitful week for Russia-Kenya bilateral relations".
