The emulations would not have to be uploads of specific human brains, nor would they need to be running in real-time.

A working definition of a human brain emulation could be a computer program that: 

The nations are those with the top 10 GDPs at the end of the year in question.

By human rights, I mean the same primary legal rights and protections as the biological human population of each nation (e.g. protection from murder, torture, theft, slavery etc), not necessarily conforming to the UN or EU declarations of human rights. Trivial legal differences that do not noticeably effect quality of life for those involved are ignored.

If the rights were already pre-emptively granted to emulations before the first ones are created, that still counts.
