WASHINGTON (Reuters) - The U.S. Senate on Friday resoundingly approved new sanctions on trade with Iran’s energy, port, shipping and ship-building sectors, its latest effort to ratchet up economic pressure on Tehran over its nuclear program.
The new package builds on existing U.S. sanctions but maintains exemptions for countries that have made significant cuts to their purchases of Iranian crude oil.
Iran’s currency has plunged this year as its oil exports were slashed by U.S. and European sanctions aimed at pressuring the country’s leadership to stop pursuing nuclear weapons.
Iran says its nuclear program is for peaceful purposes. The United Nations’ nuclear chief said on Thursday his agency has made no progress in its year-long push to investigate whether Iran has worked on developing an atomic bomb.
“We must be clear to the Iranians that toughing it out and waiting it out is not an option, that it will only get worse,” Democratic Senator Robert Menendez of New Jersey said ahead of the vote.
Menendez co-authored the package with Republican Senator Mark Kirk of Illinois and Senator Joseph Lieberman, an Independent from Connecticut.
Senators voted 94-0 to make the new sanctions part of an annual defense policy bill.
The Obama administration has not publicly commented on the proposals, but has privately raised concerns that it does not provide enough “waiver flexibility,” said Carl Levin, chairman of the Senate Armed Services Committee.
Levin said those concerns may be addressed when the Senate and House of Representatives work out differences to finalize the massive defense bill. Both bodies will need to approve the defense bill before it would be given to President Barack Obama to sign into law.
The new sanctions also include measures aimed at stopping the flow of gold from Turkey to Iran.
The American Israel Public Affairs Committee, a powerful pro-Israel lobby group, endorsed the measures, which they said would close a loophole in existing laws.
“In an effort to circumvent international sanctions on the Central Bank of Iran, some purchasers of Iranian oil and natural gas have been using gold and other precious metals to pay for petroleum products,” AIPAC leaders said in a letter to senators ahead of the vote, urging support for the bill.
