"Fuel" and "economic" do not have to be used explicitly in the article, or is reading and comprehension a lost art? Take the following paragraph, for example: > For China, the An-225 would open whole new frontiers in commercial and military air transportation. A fleet of civilian An-225s could quickly ship heavy and bulky cargoes of massive scale, ranging from construction equipment to consumer goods. For humanitarian purposes, the An-225 could support disaster relief operations, able to fly in not just large amounts of aid, but also by bringing infrastructure like power generation and water treatment that are normally too big for airlift. That spells out in plain language why possession of the An-225 and its technologies make economic sense for China. And the paragraph after that state the military reasons why China would need the An-225.
