French Prime Minister Francois Fillon urged Japanese firms and investors Friday not to turn their backs on the euro despite the recent financial crisis triggered by Greece's debt meltdown.

During a two-day visit to Tokyo, the prime minister gave a speech hosted by the French Embassy at a hotel in Minato Ward, where he stressed that the current euro crisis was not caused by the weakness of the single currency but triggered by bad management of public finances.

"It is true that the eurozone has just come through the most testing crisis in its history," Fillon said.
