Denmark's Finance Minister Kristian Jensen has warned that Washington may retaliate against the EU's plans to introduce a three percent tax on the turnover of digital giants.
Speaking to reporters on the sidelines of an EU ministerial meeting on the matter, he said that "of course there will be a reaction from the US."
In early August, Mel Stride, the financial secretary to the UK Treasury, said that the British government is ready to proceed with unilateral measures to tackle the tax evasion of such digital giants as Google and Facebook, if the international efforts on the issue come to a standstill.
Austria, in turn, insisted on exclusion of the sale of users' data from the activities covered by the planned tax, a proposal which was supported by France, Italy and Spain.
US Treasury Secretary Steven Mnuchin, meanwhile, called for a global solution to the problem, warning against "unilateral action".
"A tax should be based on income, not sales, and should not single out a specific industry for taxation under a different standard," he underscored.
In March, the European Commission proposed that EU countries should impose a three percent levy on the digital turnover of large firms such as Google and Facebook, which are accused of sending profits to countries with low taxation, such as Ireland and Luxembourg.
