Biden, during his live appearance on ABC's "The View" on Thursday, Apr 23, said that UN sanctions, which is supported by the permanent members of the UN Security Council, including China, is expected to be announced either by end of Apr or in the first week of May.
"Everyone from the Israeli Prime Minister straight through to the British prime minister to the president of Russia, everyone agrees that the next step we should take is the UN sanctions route," he said. "I believe you'll see a sanctions regime coming out by the end of this month, the beginning of next month."
"This is the first time the entire world is unified. Iran is out of bounds," Biden said.
US and its western allies that have been against Iran's pursuit of nuclear weapons, could not impose a sanction through the UN without the support of Russia and China.
China's decision to support the sanction was announced by President Barack Obama at the end of a 47-nation Nuclear Security Summit held in US.
