The Ships of The Goguryeo
The far eastern nations, compared to the Europeans, were doing much better in technology already, as the fall of Rome led to massive amounts of disorganization, and actual loss of technology. The Goguryeoans, we'll just call them the Koreans, were developing at an astonishing rate. Their culture and focus of their nation in general was moving towards a maritime society, which was understandable considering being located on a peninsula. Their relations with the Wei Dynasty were improving, and they could be considered allies at this point. Ships from this time period belonging to them have been discovered by modern-day archeologists as far away as India, and trade flourished under their rule.
The Rise of Ghana
Over in Africa, a large civilization(For the region) was developing along the Niger River, and, much like the Koreans, were profiting greatly from trade. However, this was via the rivers near them and trade caravans. Many merchants even told of "A large government falling apart" from traders in Carthago. At this time, the river was supplying much more food, as it was a lot more fertile along the sides. Ghana also was beginning to establish small trade outposts along the rivers in Africa. They also were a powerful military society, with Ghana literally meaning warrior. The military conquered many tribes around them, however the government was not yet ready to handle such a large amount of land.
The Eastern Romans
Finally, the Eastern Roman Empire which is now more well known as Byzantium, is experiencing a golden era of culture and the arts, despite their brother falling. Under Emperor Zeno, many military conquests ensued, including a successful operation against Odoacer, seizing parts of Southern Italy, eventually being the bases for further attacks on Italy, hopefully Rome will be recaptured as well. However, they also had a rival to the east. The Sassanian Empire. They were currently in an ancient form of an arms race, trying to get the best and newest technology to outshine the other.
The capital of Constantinople was also growing. Many churches were being built, and the "patriarch", a title for the head of the current church being used in Byzantium, was located in Constantinople. The title was established shorty after Rome's fall, primarily as a rank granted by the Emperor to have someone to handle religious matters. An attack was also being planned on the Vandals, who invaded North Africa, and were currently right in the way of the Byzantines.
