UNITED NATIONS — Russia and China on Tuesday vetoed a Security Council resolution aimed at reopening the Strait of Hormuz that had been repeatedly watered down in hopes those two countries would abstain.

The vote — 11-2, with two abstentions from Pakistan and Colombia — took place shortly after U.S. President Donald Trump issued an unprecedented threat that a “whole civilization will die tonight” if Iran does not open the strategic waterway and make a deal. But late Tuesday, less than two hours before the deadline he set, Trump pulled back his threat.

Trump said he would suspend the threatened attack for two weeks provided Iran agreed to open the Strait of Hormuz. One-fifth of the world’s oil typically passes through the strait, and Iran’s stranglehold during the war has sent energy prices soaring.

Russia and China strongly defended their opposition to the U.N. resolution, both citing Trump’s threat to end Iran’s civilization as confirmation that the proposal would have given the U.S. and Israel “carte blanche for continued aggression,” as Russian envoy Vassily Nebenzia put it.

Nebenzia and China’s U.N. ambassador, Fu Cong, said the resolution failed to capture the root causes and full picture of the conflict by not showing that America and its closest ally started the now spiraling war.

Fu said in his statement that resolution was “highly susceptible to misinterpretation or even abuse,” and if it were adopted “would send a wrong message and have serious, very serious consequences.”

Russia and China immediately followed up by circulating a rival resolution, seen by The Associated Press, which urged all parties to halt military activities and condemned attacks on civilians and civilian infrastructure. Nebenzia told reporters it was already in a form that could be put to a vote.

,The foreign minister of Bahrain, which authored the draft, assailed the U.N.’s most powerful body for not taking action and allowing the international community to be “held hostage to economic blackmail” from Iran.

Abdullatif bin Rashid Al Zayani said failing to adopt the resolution sends “the signal that the threat to international waterways can pass without any decisive action by the international organization responsible for the maintenance of international peace and security.”

Al-Zayani told reporters that Gulf countries will intensify diplomatic efforts to deter Iran’s attacks and safeguard freedom of navigation. But Iran’s ambassador to the U.N. thanked its allies on the 15-member council for refusing to adopt the resolution.

“The text unjustifiably and misleadingly portrays Iran’s lawful measures in the Strait of Hormuz, which have been taken in the exercise of its inherent right of self-defense in accordance with the UN Charter, as threats to international peace and security,” Amir-Saeid Iravani said in his statement.

It’s doubtful the resolution, even if it had been adopted, would have impacted the war, now in its sixth week, because it was been significantly weakened to try to get Moscow and Beijing to abstain rather than veto it.
