Iran's Foreign Ministry said that Iran is studying the American response to the observations related to the text of the nuclear agreement. The sources confirmed that if the Council approves the American response, the nuclear deal will be signed on the fifth of September.

The Iranian Foreign Ministry announced that it had received the American response to the comments it made on the final text of the nuclear agreement. An official familiar with the matter said that the US response sent to Iran falls short of Iran's expectations, Politico reported. 

The Iranian Foreign Ministry spokesman said that Tehran has begun to study the US response carefully, and its opinion will be communicated to the European coordinator. The nuclear talks in Vienna are conducted through the European powers that relay messages between Washington and Tehran. 

On Wednesday, the US State Department confirmed that Washington is sticking to the diplomatic path for a joint return to the nuclear agreement with Iran.

State Department spokesman Ned Price told Al Arabiya that the joint return of the nuclear agreement with Iran is in the interest of the United States. He also stressed that diplomacy is the best option to constrain Iran's nuclear program.

Most of the obstacles prevented from reaching an agreement last March are now gone since both Washington and Tehran have accommodated each other's demands. 

Both the US and Iran need an agreement. The US needs to distance Iran from Russia and alleviate high energy prices by flooding the market with Iranian oil after a possible deal, while Iran could get a respite from "Maximum Pressure" sanctions that have crippled the country's economy.
