Official diplomatic relations between the Kingdom of Belgium and Republic of the Philippines were established on 4 July 1946.
However, records show that as far back as 1837 a Belgian Consul already operated in Manila, and in 1845 Belgium was represented by a Consul General.
In 1935-1940, reports about the Philippines were being received from Washington, and a consul was stationed in Manila during the war. Then in 1946, reports originated from Washington, Madrid and Nanjing, but in January 1949 the Belgian government decided to open a legation in Manila with a Chargé d’affaires, Mr. Guillaume, who later presented his credentials on 25 September 1952 as “Minister of Belgium”.
