The former Barcelona president dined with City's director of football Txiki Begiristain, also formerly of Barca, and Neymar's father in London but he has made it clear that he is not acting as an agent for the English champions.
"I did meet with [Begiristain and Neymar's father] because I know them both well," Laporta told Catalunya Radio.
"I was in London and I know football people. Txiki was also in London and there were about 15 people in total at the dinner and Neymar's father was also there.
"My dream is to see Neymar playing for FC Barcelona like Ronaldinho, Romario, Rivaldo and Ronaldo did in the past.
"Neymar's father is nervous because every big club in Europe want his son and that is stressful.
"But when I saw him he comes across as a quiet man who is trying to stay calm and do the best for his son.
"Still, I was quite shocked to read that people thought I was there as agent for another club. I am not an agent I am a lawyer.
"I earn my wages doing something else, not as an agent and, as I say, it would be great to see Neymar at Barcelona."
