"In a few days I will meet Angela Merkel to present her my vision of Europe's future in details," Fillon told reporters.
He added that a number of issues, such as the victory of Donald Trump in the US presidential elections and the December truck ramming attack in Berlin, had changed the agenda of Europe, and Paris should use the opportunity to mobilize the European Union to preserve the bloc's values and strategic priorities.
According to Fillon, French diplomats should also become more active, creative and increase their own significance.
Fillon became The Republicans party's nominee after securing victory over rival Alain Juppe in November's primaries.
The French presidential elections are expected to take place in April and May 2017.
