Many industries (food, steel, electronics, energy, mining) are considered to have military strategic importance.
For instance, Japan works very hard to grow rice even though it would be much cheaper to import rice from China. It's because not being able to feed your own population is bad in a war. Energy (oil) is the same way.
The line between military and industry is often not very clear.
