The EU has announced €4bn (£3.4bn) of state aid investments in new factories producing electric batteries for cars, heat pumps and solar panels as it seeks to accelerate production and the uptake of green technologies and combat cheap Chinese imports.
The Swedish battery producer Northvolt will receive €902m in state aid to build a new factory in Heide in Germany, while a wide range of clean tech factories in France are to get a €2.5bn bump in state aid.
I think there is some legal aspect in Europe that prohibit or limit the possibility of applying tarriff against a specific country.
That’s just between EEA countries. We’re free to levy tariffs against third parties AFAIK.
