Kerry has told his French counterpart Laurent Fabius that a trip to Iran by French executives was "not helpful" and that it gave the wrong impression that the West could do business with Tehran as usual.
"The US is trying to impose a negative atmosphere over the negotiations, but Washington should come to know that Iran will take reciprocal measures," Afkham said.
She noted that while the US officials should rather try to appease Iranian nation than insisting on their unrealistic and vague attitude about Islamic Republic of Iran.
"While only few days are remaining to the new round of talks between Iran and the Group 5+1 (the five permanent UN Security Council members plus Germany), such statements ruins the positive atmosphere of talks," the Iranian foreign ministry spokeswoman said.
Afkham pointed to firm stance of Iranians with regard to their inalienable rights, and recommended the American side not to pave the already tested path and avoid pressing Iran to change its military stance on its nuclear activities.
The Iranian diplomat pointed to the ongoing visits of political and economic delegations to Iran, and said, "It is necessary that the American officials avoid being fanatic and unilateral, and instead to take a serious look at the international scene.”
A large delegation of French businessmen with 140 members arrived in the Iranian capital on Monday morning to explore avenues for expanding all-out ties with Tehran, a senior Iranian trade official announced.
On Monday, Iranian Foreign Ministry Spokeswoman Marziyeh Afkham welcomed the presence of a 140-member French economic delegation in Tehran, and described the move as one of the outcomes of the implementation of Iran-world powers nuclear deal which has persuaded so many foreign companies to look for a bigger share from Iran's lucrative market.
Deputy Head of Iran's Trade Promotion Organization (TPO) Mehdi Mir Aboutalebi announced that the visiting delegation mainly consists of industrialists and economic activists from France’s car making, mining, commercial, oil, gas, petrochemical, water, electricity, aviation, railways, roads, maritime, cement, metal, medicine, IT, ITC, hotel management, financial institutes, banking, and tourism sectors.
Mir Aboutalebi said the delegation is the largest ever to visit Iran from the European countries since the 1979 Islamic Revolution.
