The step that the USA took the other day in collaboration with Europe to strengthen the sanctions against Russia is so important, she said on Saturday according to the news agency Bloomberg.
The USA's new sanctions are intended to hit Russia's oil giants Rosneft and Lukoil. At the same time, the EU is aiming for a ban on imports of Russian natural gas.
But Valtonen does not think it is enough and believes that "we simply must increase the pressure" even more.
Unfortunately, it seems we cannot change Russia's imperialistic goals, but we should be able to change their calculations, she said.
