The ship set sail from Kuwait port, a stone's throw away from the Port of Basra; you might as well say it departed directly from its mooring port, before heading to Dubai Port to load up on arms.
After a two-day stopover in Dubai Port, having filled the vessel with ammo, it resumed its journey towards the port in Sudan.
Gao Guang had to pay four million dollars in transport fees for the entire trip.
Whether the freight cost is considered high depends on the type of cargo being transported; if it were bulk commodities like crude oil, then the four million dollars Gao Guang shelled out would be exorbitant—an outright rip-off.
But if the cargo consisted of arms and ammunition, then four million dollars could only be considered a fair price. It is certainly expensive, but not outrageously so.
Besides the costly freight, the voyage was incredibly smooth, so smooth it didn't warrant discussion.
