Asked about investigations into Kenya on British television network BT Sport, Coe responded "if it means pulling them out of world championships or Olympic Games then we will have to do that."
Coe added: "I know the World Anti-Doping Agency has looked very closely at the Kenyan National Anti-Doping Agency. We of course monitor that through the IAAF so that work is ongoing."
The IAAF has already suspended Russian athletes from global competition.
