Washington (dailynewyorknews) – The Obama administration plans to impose new sanctions against Iran Monday, diplomatic sources familiar with the plan.

U.S. sanctions prohibit U.S. companies already doing business with Iran.

The purpose of the new measures is the concern of foreign companies bar ‘, and the Iranian petrochemical industry by threatening to exclude them from the U.S. market, the sources said.

Sources declined to name because they have no right to speak before the memory of the officers Roll out the sanctions.

The measures, which sources said would be announced early Monday morning, building on existing sanctions against Iran’s oil and gas industry.

Plans for additional sanctions in the wake of a report by the UN agency nuclear watchdog in detail the evidence that the Iranian government was developing the technology needed to build a nuclear weapon.

On Friday, the International Atomic Energy of Governors approved a resolution expressing “deep concern at the growing problems unresolved with respect to Iran’s nuclear program.” However, the resolution of the UN agency did not threaten action to curb Iran’s nuclear ambitions.

Iran insists its nuclear program is peaceful and has called on the UN report “unbalanced” and “politically motivated”.

The Obama administration faces growing pressure from Congress to increase pressure on Iran, including sanctions, Iran’s Central Bank.

Last week, Republican Senator Mark Kirk, introduced an amendment that would impose sanctions on foreign financial institutions doing business with the Central Bank of Iran.

However, diplomatic sources in the United States referred to some possible sanctions in the bank, the restriction of certain financial transactions, but not cut completely.
