The 70-year-old was provisionally banned from all International Tennis Federation (ITF) events after verbally abusing opposing team members and the umpire when he captained Romania in a Fed Cup tie against Britain last month.
The former French and US Open champion had already run into trouble after making a derogatory comment about world number one Serena Williams' unborn child ahead of the World Group II playoff tie in Constanta.
"What does Wimbledon have to do with what I said about Serena and at the match in Romania?" Nastase told Romanian website ProSport. "If I did something stupid at Wimbledon then I'd understand... But in this case, I don't get it.
"In 1973, when everyone else refused to play at Wimbledon (because of a boycott by the Association of Tennis Professionals) but I did -- does that not count for something?
"If they are going to be so small-minded about it, there's nothing I can do."
The ITF said last month it was launching further investigations into the incidents during the Fed Cup tie and would make no further comment until they were completed.
