Persepolis Interstellar Treaty (PIT) Conferences were held in 1971 and again in 2011. Humans have equal standing in terms of morality but not in terms of complete sovereignty or control of their own futures in part because they're not considered to be fully grown up and able to handle themselves. 
The second PIT Conference, PIT II, was originally to be held in 2001, but that was canceled because of the 9-11 attacks. The meeting finally happened in 2011 at Paris. It took place in the back room of a G8 meeting.
