Mauritania has transitioned from a tranquil black-arab-berber bridge country between Morocco and Senegal into a succession of arab nationalist pseudo-islamist autocratic military regimes that discriminate it's black citizens since the late 80's so that is a natural opposite of Senegal which is a majority muslim but staunchly secular black african democratic state with true ethnic and religious harmony. SInce these borders make no sense, the non-arabised citizens of southern Mauritania are indistinguishable from those of northern Senegal and the successive mauritanian regimes have always feared the Senegalese government helping that minority to take power or at least have their rights respected. Also Senegal is Morocco's best ally in Africa and Morocco has always been nostalgic as they claim Mauritania as part of her empire (unofficially they don't but still). That is a serious threat if they would ally against Mauritania. I am not part berber mauritanian but part of my family is hassaniya speaking.
As for Guinea it's less serious than with Mauritania, it's a sort of rivalry and jealousy but also Senegal is a safe haven for fulani opposition and fulani civilians. This has been so since the times of Ahmed Sekou Touré. And ofc the successive guinean governments who have always adopted "anything but a fulani in power tactics" do not like that.
It's not a coincidence Jammeh only listened to Condé of Guinea and Abdel Aziz of Mauritania, and his head was saved by them in the last minute. They are united in their dislike for Senegal if they could they would try to keep him in power. But Senegal and Ecowas didn't leave that option open.
What a mess.
