Why Belgium and Rwanda are expelling each other’s diplomats

Rwanda has severed diplomatic relations with Belgium, compelling all Belgian diplomats to vacate within 48 hours.
The Rwandan foreign ministry said the decision, effective immediately, follows careful consideration due to Belgium's historical negative impact on Rwanda and its perceived neocolonial attitudes.
Rwanda assertively aims to protect its national interests and the dignity of its citizens while promoting sovereignty and mutual respect.
In light of these developments, Belgium condemned Rwanda's actions as "disproportionate" and expressed regret over the termination of diplomatic ties. Maxime Prevot, Belgium's Deputy Prime Minister, said that Rwanda's preference for disengagement rather than dialogue was apparent.
Belgium announced reciprocal actions, including declaring Rwandan diplomats persona non grata and ending governmental cooperation agreements.
Amidst these developments, two regional groups, the Southern African Development Community (SADC) and the East African Community convened in Harare to discuss peace measures for the eastern DRC.
