Today’s passing of the Trans-Pacific Partnership bill included a quiet but meaningful amendment targeting the boycott Israel movement.

The measure passed by the United States Congress on Wednesday includes an amendment requiring American negotiators to stipulate the rejection of boycotting Israeli products as a core principle in any trade talks that might occur with the European Union.

The trade bill—whose amendment takes a stand against the anti-Israel Boycott, Divestment and Sanctions (BDS) movement—initially passed with a majority in the House of Representatives last week, followed by Wednesday’s affirmative 60-38 vote in the Senate.

The goal of the anti-BDS amendment is to enshrine “a principal negotiating objective that reinforces our opposition to official actions that boycott, penalize, or otherwise limit commercial relations with the State of Israel,” U.S. Rep. Paul Ryan (R-Wis.) said when introducing the amendment, the Jerusalem Post has reported.

By passing the bill with the amendment, Congress “has completed a major step to defend Israel from pernicious economic efforts by foreign governments to unfairly target our democratic ally, and to protect American businesses operating in Israel,” the American Israel Public Affairs Committee said.

Efforts to boycott Israeli products in Europe have seen a major uptick in the past year.
