"The EU is willing to maintain trade relations and cooperation with Iran and Iranian companies," Radej told Fars News Agency on Tuesday.

She said Slovenia has earlier expanded banking ties with Iran, adding that two Iranian banks, Bank Mellat and Pasargad Bank, enjoy good relations with Slovenian Gorenjska Bank.

US President Donald Trump announced on May 8 that the US would no longer remain part of the Joint Comprehensive Plan of Action (JCPOA) and promised to re-impose the highest level of economic sanctions against Iran in response to Tehran's development of its nuclear program.

After Trump's declaration, the Iranian government issued a statement, calling the US withdrawal as 'unlawful'. The statement underlined Iran's prerequisites for continuing the deal with the world powers after the US pullout.
