The FIA has played down concerns that Red Bull and AlphaTauri are collaborating beyond what is allowed in Formula 1's technical regulations.
The two Red Bull-owned squads are set to work even closer together next year with AlphaTauri utilising more parts from its sister squad.
F1's regulations have a list of parts that may be used between teams however key areas such as the bodywork can't be outsourced.
Concerns have been raised by rival teams over the legality of the partnership between Red Bull and AlphaTauri.
The Head of Single Seaters at the FIA Nikolas Tombazis has stated that initial analysis has shown no wrongdoing from the teams and stated it is not the only collaboration that needs looking into.
"It's not just a problem between these two teams, but also between other pairs of teams," he said, as quoted by Motorsport-Total.
"We believe that AlphaTauri has completely different aerodynamic solutions to the other team and we don't believe there is any evidence of direct collaboration.
"It is clear that they are working hard and have made a step forward. But I don't believe that this is due to a collaboration.”

FIA to implement guidelines
Tombazis revealed that teams will be issued guidelines to prove to the FIA that they are operating legally.
“One of the most difficult aspects of monitoring is cooperation and ensuring that this doesn't happen,” he said.
“We have to check and make sure that all these teams are well separated and so on.
"And we will be issuing further guidelines shortly to give the teams more information on how they can convince us that nothing like this is happening," he announces.
"We are not underestimating the challenge, and that is one of the difficulties we are facing.”
