The Syrian Foreign Ministry on Tuesday condemned the U.S. decision to reimpose sanctions on Iran, saying it supports Iran in the face of the "aggressive" U.S. policies, according to the state news agency SANA.

The ministry said the sanctions were "unilateral and illegitimate measures that come to confirm the tendency of hegemony and arrogance of the policies of the U.S. administration after losing credibility upon withdrawing from the Iranian nuclear deal."

While expressing full solidarity with Iran, Syria's government key regional backer, the ministry said the Syrian government is confident that Iran will overcome the negative outcome of the U.S. sanctions on Iran.

Despite a global outcry, the White House on Monday vowed to reimpose and fully enforce sanctions on Iran lifted under the nuclear deal.

The first batch of sanctions, which went into effect on Tuesday, target Tehran's purchase of U.S. banknotes, trade in gold and other precious metals, as well as the use of graphite, aluminum, steel, coal, and software used in industrial processes.

They will also affect transactions related to the Iranian Rial, the issuance of sovereign debts, and the country's automotive sector.

Another round of sanctions, to be reinstalled on Nov. 5, will be on Iran's port, energy, shipping and shipbuilding sectors, its petroleum-related transactions, and business deals by foreign financial institutions with the Central Bank of Iran.

The Trump administration will also relist hundreds of individuals, entities, vessels, and aircraft that were previously included on sanctions lists.

Washington said it would reimpose tough sanctions on the Iranian government when it declared to leave the Iran nuke deal in May. It also laid out two wind-down periods of 90 days and 180 days for business activities in or involving Iran.

The latest sanctions were reimposed after Monday, the final day of the 90-day wind-down period.

Accusing Tehran of having "exploited the global financial system to fund its malign activities," the White House said. "The Trump Administration intends to fully enforce the sanctions reimposed against Iran, and those who fail to wind down activities with Iran risk severe consequences."
