The Knesset on Tuesday approved a bill prohibiting the establishment of diplomatic missions in Jerusalem that are not embassies, a move aimed at bolstering Israel’s claim to the city.

The legislation, an amendment to the Basic Law: Jerusalem, Capital of Israel, was approved 29-7 and was sponsored by MKs Ze’ev Elkin (New Hope) and Dan Illouz (Likud). It stipulates that no new consulates will be established in Jerusalem, while the government will encourage the establishment of foreign embassies in the city.

The bill will not affect the status of already existing diplomatic missions in the Israeli capital.

“Jerusalem is the core of our sovereignty,” Illouz stated, asserting that the new law “makes it clear once and for all that Jerusalem is ours and is not for sale. It’s a historic law that joins other historic laws passed in recent days.”

Elkin said that “those who wish to establish a foreign mission in Jerusalem will have to act according to this law and the mission will be obligated to provide service to the residents of the State of Israel. Jerusalem is the eternal and indivisible capital of the State of Israel and no country will be allowed to challenge our sovereignty in the united Jerusalem.”

Most countries do not recognize Jerusalem as the capital of Israel and base their embassies in Tel Aviv, often opening smaller consulates in Jerusalem. Currently, five countries — the US, Guatemala, Honduras, Kosovo, and Papua New Guinea — have embassies in Jerusalem.

The law is also widely seen as intended to prevent the establishment of consular offices serving Palestinians in the Israeli capital.

In May, four Dutch political factions agreed in their coalition pact to look into finding the appropriate timing for moving the embassy of the Netherlands in Israel to Jerusalem.

Israel considers Jerusalem to be its capital, including East Jerusalem, which it annexed in 1980. Most of the international community says the final borders of the city should be decided in negotiations with the Palestinians.

Former US president Donald Trump moved his country’s embassy to Jerusalem in 2018 in what Israel hoped would lead to a flood of countries to follow suit, though that has yet to happen.
