The United States has revived attempts to include language on homosexuality in a United Nations resolution condemning unjustified executions.
The ABC reports African and Arab states, some of which outlaw homosexuality, narrowly succeeded in deleting the reference when a UN panel preparing the draft voted last month.
But the American ambassador at the UN says Washington is determined to restore it.
Susan Rice says she wants an explicit reference to executions over a person's sexual preference.
"We urge you to stand again with us, and with all vulnerable people around the world at risk of violence," she said.
"We're going to fight to restore the reference to sexual orientation. We're going to stand firm on this basic principle, and we intend to win."
