France is working on a draft United Nations Security Council resolution backing freedom of navigation in the Strait of Hormuz, a U.N. diplomat said on Friday.

The diplomat, speaking on condition of anonymity because discussions on the measure have been private, said the resolution would reaffirm the need to respect freedom of navigation in the strait and cite its importance for global shipments critical for food and energy security.

The proposed resolution would recall the need to respect the Law of the Sea and support peaceful initiatives aimed at ensuring safe passage in the strait, the diplomat said.

The Strait of Hormuz is a flashpoint in the war in Iran. Before the war, a fifth of the world's traded oil and gas transited through the strait.

The White House said on Friday that U.S. officials are having positive and constructive conversations with mediators on the Iran war.
