Until the Qatar diplomatic crisis, Qatar imported upwards of 80% of its food from its Persian Gulf neighbors, chiefly Saudi Arabia. The vast majority of food was transported on land through the Salwa Border Crossing connecting both countries. This border crossing was closed in June 2017 and Qatar's trade with the blockading countries was suspended, thereby cutting off Qatar from its primary source of food imports.[32] Imports of pharmaceuticals were also interrupted in Qatar, of which 50 to 60% was supplied by Saudi Arabia and the other Arab countries in the Persian Gulf.[33]
