Yes is conditional on diplomatic/public meetings with intelligent non-human lifeforms, that predate humanity's evolutionary branching from primates. This is also specific to a negotiation type meeting, even if only a empty formality, this does not include meeting aliens in a clandestine, top secret/not publicly acknowledged way.

No is if ETs/aliens/NHI don't exist, and therefore no negotiations with entities from space could be possible, except for strange exceptions, like spacefaring timetraveling humans.
