Force India says it would be against any form of co-operation deal between Honda and Mercedes to help the Japanese manufacturer with its Formula 1 engines.
As recently reported by Autosport, Mercedes has opened talks with Honda to see if there is scope for it to offer assistance to its rival to help it overcome its performance and reliability problems.
It is understoond that no final decision has been taken about if they will work together.
At the Spanish Grand Prix on Friday, Force India deputy team principal Bob Fernley - whose squad is a Mercedes customer - expressed his opposition to such a partnership.
"As a team obviously that has not only paid for its engines, but contributed to the development of them, I would certainly be very negative with sharing that technology with another team that is a competitor," said Fernley.
Mercedes motorsport boss Toto Wolff declined to elaborate on the extent of talks with Honda, but insisted that nothing had been finalised yet.
Pushed on what exactly Mercedes was doing with Honda, Wolff said: "We are not doing anything for Honda, that is the current status quo.
"So unless that situation changes, I don't want to contribute to rumours out there that are false and I think are damaging for Honda, and create hard standpoints from teams or other stakeholders.
"We will see what happens."
Wolff added that he believed ultimately Honda would get on top of its situation.
"It is important for F1," he said.
"Honda is an important factor in F1, a massive and very successful company and I have no doubt they will eventually be where they expect to be."
