As he stressed that the sanctions against the Islamic Republic are fruitless, Iranian President Hasan Rouhani said that many western firms are expanding their cooperation with Tehran.

In a meeting with South African Foreign Minister Maite Nkoana-Mashabane in Tehran Sunday, Rouhani said the US-led incorrect and unfair sanctions system has cracked and is in trouble now.

"The continuation of unfair sanctions against Tehran is impossible and the western firms are now in negotiations (with Iran) and endorsing cooperation contracts with Iran,” FNA quoted Rouhani as saying.

President Rouhani also referred to the ongoing talks between Iran and the world powers on Iran's nuclear program, and once again stressed that Iran is serious in its talks with the world powers.

"The Islamic Republic of Iran is ready to reach final results in its nuclear talks with the Group 5+1 (the US, Russia, China, Britain and France plus Germany) within the framework of the international laws and regulations.”

On November 24, Iran and the world powers sealed a six-month Joint Plan of Action to lay the groundwork for the full resolution of the West’s decade-old dispute with Iran over its nuclear energy program. They held several round of talks by now and expressed the hope that they will reach a comprehensive deal until July 20.

Different European countries, including France, Germany and the Netherlands, are planning to enhance their economic relations with Iran, a business powerhouse in the Middle East region, as sanctions imposed against Tehran are partially suspended.
