US President Donald Trump's administration is discouraging governments around the world from attending a UN conference next week on a possible two-state solution between Israel and the Palestinians, according to a US cable seen by Reuters. 

The diplomatic demarche, sent on Tuesday, says countries that take "anti-Israel actions" following the conference will be viewed as acting in opposition to US foreign policy interests and could face diplomatic consequences from Washington.

The demarche, which was not previously reported, runs squarely against the diplomacy of two close allies, France and Saudi Arabia, who are co-hosting the gathering next week in New York that aims to lay out the parameters for a roadmap to a Palestinian state, while ensuring Israel's security.

"We are urging governments not to participate in the conference, which we view as counterproductive to ongoing, lifesaving efforts to end the war in Gaza and free hostages," read the cable.

President Emmanuel Macron has suggested France could recognise a Palestinian state at the conference. French officials say they have been working to avoid a clash with the US, Israel's staunchest major ally.

US opposes recognizing a Palestinian State

"The United States opposes any steps that would unilaterally recognise a conjectural Palestinian state, which adds significant legal and political obstacles to the eventual resolution of the conflict and could coerce Israel during a war, thereby supporting its enemies," the cable read.

This week, Britain and Canada, also G7 allies of the United States, were joined by other countries in placing sanctions on two Israeli far-right government ministers to pressure Prime Minister Benjamin Netanyahu to bring the Gaza war to an end.

"The United States opposes the implied support of the conference for potential actions including boycotts and sanctions on Israel as well as other punitive measures," the cable read.

Israel has repeatedly criticised the conference, saying it rewards Islamist Hamas militants for the Oct. 7, 2023 attack on Israel that triggered the Gaza war, and it has lobbied France against recognising a Palestinian state. 

The US State Department and the French Foreign Ministry did not immediately respond to requests for comment.
