SHANA � Iranian Minister of Petroleum Bijan Zangeneh says collaboration of countries puts pressure on US unilateralism.

Speaking on Saturday, the official said the above in response to a question whether the recent deals Iran has signed with foreign companies would have any effect on US Prescient Donald Trump's threats against Iran.

During President Vladimir Putin's visit to Tehran on Wednesday, Russia's state oil producer Rosneft and the National Iranian Oil Company agreed on the outlines of a deal for up to $30 billion worth of energy projects, as Russian companies continue to expand their studies on Iranian oil and gas fields.

Mr. Zangeneh also said that France's Total S.A. has started working on phase 11 project of the supergiant South Pars Gas Field in Persian Gulf.

In July, Total signed a $5-billion deal to develop South Pars Phase 11 in collaboration with China's CNPC and Iran's state-owned Petropars.

The Iranian Minister of Petroleum added that talks are on the go with Russia's Gazprom for developing four gas fields in the Persian Gulf, namely Kish, Farzad-A, Farzad-B as well as the North Pars.

"Gazprom asked us for more time for presenting the result of its studies on the projects and we gave them the time," he said.
