Outside of Europe and England, what was going on in the rest of the world like (Africa, India, China, Japan etc) during the post collapse of Rome and the time leading to the renaissance?
This is an incredibly broad question. Just off the top of my head, I could talk to you about the personal choices of noble titles for Maya kings in Mexico, the the role of cavalry sculptures in funerary traditions of the Northern Wei dynasty in north China, or the stonework in doorways of the Recuay of highland Peru. If there a particular area and topic you're interested in?
A very short and therefore incredibly inaccurate answer would be that Europe's dark ages were China and the Islam world's gold ages. Trade in the Indian ocean, all the way from Egypt to Korea and Japan, was thriving. Scientific progress and productivity soared. Even sub-Saharan Africa was doing pretty well.
Now..... if you want to know more, you'll really have to elaborate.
It may be a bit later than you're looking for, but New Zealand was first colonized by humans ~1200-1300 AD. So around the late middle ages, Maori culture was beginning to diverge from its polynesian roots.
Simple answer: No. Following the collapse of Roman imperial authority in Western Europe, true political unity and peace didn't return for centuries. Following the collapse of classical empires in China and the Middle East, successful states returned within relatively small amounts of time (Tang and Sung dynasties, Abbasid and Fatimid caliphates), within which technological innovation, intellectual achievements, and economic development continued. Mongol conquests and trade helped bring Europe into the greater Afro-Eurasian network, arguably leading to the Renaissance.
