The resolution aimed to extend sanctions relief under Security Council Resolution 2231 for six months to allow further diplomacy.
Russia, China, Algeria, and Pakistan voted in favor, while the United States, Britain, France, and five other members opposed it. Guyana and South Korea abstained.
Dorothy Shea, Acting US Representative to the UN advised Russia and China to ask Iran for full cooperation instead of postponing the sanctions.
“They must press leaders in Tehran to take meaningful immediate steps to fulfill its commitments and obligations, including by fully cooperating with the IAEA,” Shea said.
British ambassador to the UN Barbara Woodward told the Security Council the doors to diplomacy are not yet closed.
"The United Kingdom remains committed to pursuing a diplomatic solution that ensures Iran never acquires a nuclear weapon, while maintaining Iran's right to a civil nuclear program in line with the nuclear Non-Proliferation Treaty."
