Stuart Jones, the top USA diplomat in charge of the Middle East, said the U.S.is still forming a "comprehensive Iran policy" that includes Iran's support for Syrian President Bashar Assad's government and militant groups in Lebanon, Iraq and Yemen.
The Islamic Republic underlined that will not stop its missile program amid a new round of sanctions imposed by U.S. on Iranian and Chinese figures for supporting Iran's ballistic missile program.
Under the terms of the 2015 deal, the previous U.S. administration of president Barack Obama agreed to waive sanctions on Iran's nuclear program in return for controls to prevent its developing a bomb.
At the same time, the Trump administration imposed new penalties on Iranian and Chinese entities for supporting Iran's ballistic missile program.
While both the US State Department and the United Nations nuclear watchdog agency report that Iran is compliant with the nuclear deal, evidence provided last month by the Iranian Resistance shows that the Regime has simply moved their base of operations to a secret site, resumed working on advanced centrifuges, and refused access to independent inspectors.
China lodged an official protest with the United States today over new U.S. sanctions on Iran that target a Chinese business tied to Tehran's ballistic missile programme.
On Wednesday, Iranian state media outlets said four passenger airplanes were being delivered as the first installment of a deal with French-Italian manufacturer ATR that was finalized after the nuclear agreement.

The Iranian Foreign Ministry on Thursday imposed sanctions on nine U.S. firms and individuals in retaliation for new sanctions on the Islamic republic over its missile programme.
Finally, Iran-based Matin Sanat Nik Andishan, a company that has provided materials useful to Iran's liquid-fueled ballistic missile program, was listed for sanctions. But continuing the sanctions relief requires the renewal of a six-month waiver.
The development shows that Trump's softened stance on the Iran Nuclear deal and comes ahead of the President's five-country which includes stops in Saudi Arabia and Israel.
Iran Foreign Ministry spokesman Bahram Qasemi was quoted as saying."Iran condemns United State's unacceptable ill will in its effort to undermine the positive outcome of Tehran's commitment to implement the nuclear deal by adding individuals to its list of unilateral and illegal sanctions".
US lawmakers, as well as Trump administration insiders, have become increasingly concerned over Iran's repeated ballistic missile tests since the landmark nuclear agreement was inked. "And above all, the United States will never allow the regime in Iran to acquire a nuclear weapon", he added.
But for now, Trump seems to be abiding by the Iran deal.

But the USA will also impose new economic penalties related to the country's missile work.
