Red Bull has joined Ferrari in saying it will not race in Formula 1 next season if FOTA's demands are not met, despite being granted an entry for 2010.
Red Bull, Toro Rosso and Ferrari were given unconditional entries for next year, while the other five FOTA teams were asked to drop their conditions if they are to race in 2010.
Ferrari, however, made it clear on Friday that it will not race if the conditions demanded by FOTA are not met.
The Italian team has now been followed by Red Bull, who said in a statement it remains committed to FOTA.
"Following the FIA's publication of the entry list for the 2010 FIA Formula One World Championship, Red Bull Racing would like to make it clear that its entry was submitted as a conditional entry, consistent with those of all other FOTA members," said the statement.
"Red Bull Racing remains committed to FOTA and fully endorses all its principles."
