The second company looked promising too, because they are based in the region that produces the natural resources to make our components.
Everything needed for their activities is available on their doorstep.
They have a good working relationship with the local mine owners, who are known to have good safety records.
During my visit, the company went into great detail about the quality inspections carried out on the material before it leaves the mines.
This company seemed to have no problems with transport - until I looked more closely.
The factory is in a very mountainous region, about six hundred kilometres from the capital city.
Passenger flights are fairly frequent, taking under two hours, but the journey by road can take days.
The roads are really inadequate - the whole infrastructure needs massive investment.
There is a seaport just over the border with the neighbouring country, which would certainly cut down on distance,
but, as far as I can see, it might also bring other problems.
We simply can't risk depending on such fragile communications.
The third company I looked at, on the other hand, is on the coast, with good access to the main seaport.
Transport and shipping of goods are well organised and, in fact, they own a haulage company as one of their subsidiaries.
The production unit is new - built and equipped with the help of investment from the Ministry of Industry.
What's more, company workers are involved in decision-making, and industrial relations are excellent. Perfect so far.
