We have seen reports about how the tunnel trade in Gaza has been reversed from imports to exports. Many fruits and vegetables are more expensive in Egypt than in Gaza.
Over the weekend, an Egyptian man became enraged over how much his wife paid for tomatoes, and threw her off the second-floor balcony. She was badly injured.
So why doesn't Egypt import Gaza vegetables? As far as I can tell, there is no agreement with Israel prohibiting Egypt from doing that. The Rafah crossing is not optimized for trucks, but certainly some amount of goods could be sent through.
