It should be noted that Japan's steel production at this time was only around 100,000 tons, while the Far East Empire might only be at the level of twenty to thirty thousand tons. This really highlights the terrifying steel production of Belgium, and without a doubt, a large portion of Belgian steel was exported to France.
Belgium is rich in domestic coal mine resources, and iron ore basically meets the demand as well. The Belgian Congo also has relatively rich iron ore resources. The combination of these two, along with France's demand, is the main driving force behind Belgium's steel industry development.
Of course, the iron ore from Belgian colonies is also one of the important sources of East Africa's imported iron ore, with Cabinda's steel industry depending quite heavily on the iron ore from the Belgian Congo.
