The meeting with Juncker revolved around the Slovenia-Croatia border arbitration.

Posting a photo with Juncker on Twitter, Pahor said they discussed "subsequent steps in the implementation of the arbitral tribunal's award."

In talks with Akufo-Addo, Pahor said that Slovenia was planning to strengthen its economic and political presence in Africa, according to his office.

Slovenia's trade with Ghana remains modest but it rose 60% in 2017 to EUR 9m.

Cerar met with Gargash after Slovenia earlier this year opened an embassy in the United Arab Emirates. The first session of a joint commission for economic cooperation is scheduled for later this year.

Cerar raised the prospects of closer cooperation in civil aviation and presented the work of the Slovenian-run demining fund ITF, according to the Foreign Ministry.

He also met Hungarian counterpart Péter Szijjártó, with whom he discussed infrastructural projects, including the Koper-Divača rail track, the construction of a transmission line between Cirkovce in the north-east of the country and Pince on the border with Hungary, and cross-border roads.

The ministers praised the excellent and versatile relations between Slovenia and Hungary, especially in business, and exchanged views on the situation in the Western Balkans.
