"Anderson vs. GSP is meaningless," said Belfort to Terra Magazine. "It would make sense if Anderson fought Jon Jones."
Dana White has expressed interest in having Silva fight St-Pierre and Jones. Silva only has two fights left on his contract, but told White he is going to resign with the addition of 10 fights.
St-Pierre made a successful return after being away for 19 months due to a torn ACL. Jones has stopped all of his fights since winning the title in 2011.
"Anderson is a fighter at another level," said Belfort. "I'm not underestimating Jones, but appraising Anderson. He's one of the best that has existed."
Belfort, who was the last to loss to Jones, returns at UFC on FX 7 against Michael Bisping (23-4). The January 19 card takes place out of his home country, Brazil.
