KONFRONTASI-Sudan's cabinet has approved a ban on importing agricultural and animal products from Egypt, according to Sudan's state news agency SUNA.
The cabinet on Tuesday urged the private sector to import products directly from countries of origin, bypassing Egypt. A reason for the move was not publicised.
Ahmed Abu Zeid, the spokesman for Egypt's foreign ministry, said Cairo was told the decision was due to "a technical procedure".
Sudan banned all Egyptian agricultural goods in March.
Foreign firms have been caught in the crossfire. Saudi Arabia's Savola Group has had to re-route much of its Egypt-based sugar output that it normally sells to Sudan. Savola imports raw Brazilian sugar and refines it in Egypt for export.
"The volumes going there are about 20,000 tonnes a month, but now unfortunately this looks like it will be stopped indefinitely," a source at the company said.
The neighbours have been at odds over issues that include a long-running dispute over land on Egypt's southern border with Sudan, as well as trade restrictions and burdensome visa requirements that have threatened commercial relations.
Sudan this month accused Egypt of supporting rebels who it says want to topple the government in Khartoum. Egypt's President Abdel Fattah el-Sisi rejected the charge.
