(JTA) — European Union foreign policy chief Catherine Ashton plans to draft guidelines by the end of the year requiring all products from Israeli settlements in the West Bank, east Jerusalem and Golan Heights to be labeled as such.

In a letter sent earlier this month and exposed this week by Haaretz, Ashton asked several EU commissioners to support the move. Ashton claims that a majority of the EU’s 28 member states support labeling settlement products, and that the policy relates closely to the EU’s view that all Israeli West Bank and Golan Heights settlements are illegal under international law.

Three countries — the United Kingdom, Holland and Denmark — already label settlement products.

The guidelines would be nonbinding, but most EU states are expected to adopt them.

“An overwhelming majority of Member States have recently supported or openly demanded the preparation of EU-wide guidelines on this issue in order to implement EU law in a coherent manner,” Ashton wrote, according to Haaretz.

The letter comes as the EU has passed new regulation prohibiting the awarding of grants to companies with activity in the Israeli settlements. The regulations also require that any agreement between the EU and Israel state that the West Bank and Golan Heights are not included in Israel.
