France will implement digital tax: economy minister

France will go ahead with a digital tax, Economy Minister Bruno Le Maire said Friday, shortly after US President Donald Trump threatened "substantial" retaliation over Paris targeting top US tech companies.

"Universal taxation of digital activities is a challenge for us all. We want to reach an agreement within the G7 and the OECD. In the meantime, France will implement its national decisions," Le Maire said in response to Trump's warning.
