French President Emmanuel Macron on Wednesday condemned what he called Turkey's "reckless and dangerous" statements backing Azerbaijan it its bid to take back the breakaway region of Nagorny Karabakh.
Ankara said on Tuesday it was "fully ready" to help Azerbaijan recover Nagorny Karabakh, as armed conflict escalated with neighboring Armenia over the region.
Turkish Foreign Minister Mevlut Cavusoglu also said on Wednesday that French solidarity with Armenia amounted to supporting Armenian occupation in Azerbaijan.
He was speaking in an interview with state-run Anadolu news agency.
"I have noted Turkey's political statements which I think are reckless and dangerous," Macron told reporters in Latvia's capital Riga during a visit to the Baltic EU state.
"France remains extremely concerned about the bellicose comments that Turkey made in the last hours, which essentially remove any inhibitions from Azerbaijan in what would be a reconquest of northern Karabakh. That we will not accept," he added.
He also appeared to voice support for Yerevan: "I say to Armenia and to the Armenians, France will play its role."
But Macron also said it was too soon to speak of a regional conflict.
He said he would discuss the tensions with Russian President Vladimir Putin on Wednesday evening and US President Donald Trump on Thursday before reporting on the situation to the European Council of EU leaders.
