French Defense Minister Florence Parly told her NATO counterparts not to be afraid of the European Union's plans to develop the defense project.
She said such a project would strengthen the NATO alliance and that the United States would also benefit.
Her comments, made during a meeting of NATO defense ministers, are aimed at ending insecurity within NATO.
There have been concerns that the EU's attempt to develop its defense project would be a NATO rivalry.
"When I hear some statements about European defense, including within this organization, I tell them: do not be afraid," said Parly.
"European defense is not being built in opposition to NATO, on the contrary: a stronger Europe will contribute to a stronger alliance," she added.
The French minister echoed a statement issued after a meeting between US President Joe Biden and French President Emmanuel Macron in September, in which they said they "recognize the importance of a stronger and more capable European defense, which contributes positively to transatlantic and global security ”.
Of the 27 EU member states, 21 are members of NATO.
