The minister has been promoting its reopening after international sanctions against Iran were lifted in late January.

President Borut Pahor should attend the embassy opening during an official visit to Iran, Erjavec told MPs at the session of parliamentary Foreign Policy Committee on Wednesday.

He said that an appropriate building had already been found and that a Foreign Ministry official was currently making all the necessary arrangements in Iran. He also thanked Slovenian companies present in Iran for their assistance.

As for Brexit, MP Marko Ferluga of the ruling Modern Centre Party (SMC) asked the minister if the Slovenian diplomatic service and economy were preparing for the opportunities that could emerge from the UK's exiting the EU, especially if companies start leaving the British Isles.

Erjavec said that Brexit must happen first; concrete negotiations will only start after the exit procedure is launched, which is expected next year, he explained.

Slovenia is interested in investments from all countries, not just the UK, but the chances of attracting banks moving out of the City to Slovenia are slim, Erjavec said. "Ljubljana is not Frankfurt as far as banking centres are concerned."

The minister does, however, see opportunities in the car industry, where Slovenia's cluster is strong, generating 12% of GDP. The government will do all it can to attract companies, he asserted.

Responding to a question from SMC MP Branislav Rajić, Erjavec presented Slovenia's guidelines for the UN summit on refugees, which will be held in New York on 19 September.

Slovenia will be represented by President Pahor, who will co-chair one of the debates at the meeting.

In the preparations for the summit, Slovenia has highlighted the need for shared responsibility, arguing that transit countries should also carry their part of the burden of managing migrations, Erjavec said.

Migration has not been caused merely by source countries, but also by international circumstances. The underlying reasons for migrations such as armed conflicts and poverty must also be eliminated.

Slovenia has also emphasised the need for solidarity and enhanced the fight against human trafficking, devoting the most attention to the vulnerable groups such as children, women, the elderly and the disabled, Erjavec said.

The minister, meanwhile, refused to comment on the upcoming referendum on refugee quotas in Hungary. The opinion of some was expressed by Luxembourg's Foreign Minister Jean Asselborn, who said that Hungary should be expelled from the EU, he said.

Erjavec reiterated that European countries must show solidarity and help manage the migrations. "I cannot imagine a strong, integrated and united EU without solidarity," he told the Foreign Policy Committee.
