Sweden, whose citizen has been jailed by Eritrea for more than ten years without charge, has moved to block the flow of diaspora money to the isolated Red Sea nation. Its parliament, Riksdag, is preparing legislation to block a two per cent mandatory tax collected by Eritrea from its citizens living in Sweden. Sweden has been demanding that Asmara releases Eritrean-born Swedish journalist Dawit Isaak who has been in jail since 2001 for being critical of President Isaias Afewerki's government.
