Neymar, who joined in PSG's Ligue 1 title celebrations on Saturday night, refused to discuss his future after collecting his France's player of the year award.
"We talk about these things every time the transfer window comes around. I don't want to talk about anything at the moment," he said.
"Everyone knows why I came here, what my objectives are. Right now, my objective is the World Cup, not talking about transfers.
"I spend my whole life, every transfer window, talking about it. It's a bit annoying."
Neymar was signed from Barcelona for a world-record 222 million euros ($264 million) last August, and helped PSG on their way to a clean sweep of the domestic trophies.
However, his injury appeared to cost Unai Emery's team dear in their Champions League last-16 tie against Real Madrid -- he was unable to play in the second leg, and PSG lost 5-2 on aggregate.
He is hoping to be back to full fitness in time to lead Brazil at the World Cup in Russia, which starts in a month's time.
Club president Nasser Al-Khelaifi insisted on Saturday that there was no chance Neymar would be leaving.
"I am 2000 percent sure he will stay," Al-Khelaifi said, rejecting talk of a transfer to Real Madrid.
"The Spanish media have been talking since October. I don't respond to rumours, I don't have the time. But I am sure he will be a Paris Saint-Germain player."
