Comparing the situation to the rise of fascism before World War II, Oury Bah said he had observed "radicalisation against immigrant populations all over the world".
"It's a question that talks to us. We have a large African population in Europe," said the prime minister of the military-dominated government of the former French colony.
"We are concerned by the situation."
However, Oury Bah said he would be willing to work with far-right leaders should they come to power.
In an interview with Radio France Internationale, he indicated he would be prepared to work with Jordan Bardella if the leader of France's anti-immigrant National Rally were appointed prime minister.
Bardella's party inflicted a crushing defeat on Emmanuel Macron's centrist alliance, prompting the president to take a surprise gamble and call snap national elections.
Oury Bah said a National Rally-dominated parliament "does not worry us too much... we know that we'll deal with any government in the French Republic and even in Europe."
"I'm not overly pessimistic," he added.
