Aramex PJSC (DFM:ARMX) is in advanced talks to buy MNG Kargo Domestic and International Freight Inc., three sources said. The potential deal, which one of the sources familiar with the matter said could be worth as much as $500 million, comes as relations between regional rivals the United Arab Emirates and Turkey show signs of improvement. One of the sources said the talks were at an advanced stage and a second said the pair were engaged in due diligence. “As a matter of course, we do not comment on rumour or speculation,” an Aramex spokesperson said. MNG Kargo declined to comment.
