According to a research by the European Parliament research institute the trade between the European Union and Judea and Samaria represents only one per cent of the total trade between the EU and Israel. “Trade is so low because of high EU tariffs on Jewish goods. Elimination of EU tariffs on Jewish goods would boost trade and employment in the area. European consumers would get cheaper goods and more Jews and Palestinians would find jobs if we cut tariffs,” says Petr Mach, MEP.
