"The problems cannot be solved resorting to talking alone, since in order to resume direct talks between Tehran and Washington serious practical measures are needed," Manouchehr Mottaki said in an interview with the Bahraini Arabic language daily the Al-Balad published on Monday.
"It is true that Mr. Barack Obama has resorted to adopting a new literature towards Iran, but it should not be limited to literature, and as I have said one cannot resolve problems with words," he added.
Mottaki further underlined that Tehran, too, has adopted a different tone towards the new US administration, adding if Washington takes practical steps Tehran will follow suit.
Earlier in March, Supreme Leader of the Islamic Revolution Ayatollah Seyed Ali Khamenei also called for a real change in Washington's attitude towards Tehran, saying that the US has shown no practical change in its hostile policies on Iran.
"They give the slogan of change but in practice no change is seen ... We haven't seen any change," Ayatollah Khamenei said in a televised speech to mark the Iranian New Year.
The Iranian foreign minister also told the paper that the change in the US political literature is comparable with the Iranian President Mahmoud Ahmadinejad's congratulatory massage to the American people following the victory of Obama, saying this was the first time that such as message was sent by an Iranian President to the United States.
In response to a question about Turkey's relations with the Persian Gulf Cooperation Council (PGCC) members and Ankara's role in regional security, Mottaki said Turkey is an Islamic country and Tehran would welcome closer ties between Ankara and other regional countries.
Elsewhere, Mottaki rejected that there has been a kind of tension between Iran and the group of countries known as moderate Arabs, arguing, "We enjoy good relations with the Persian Gulf littoral countries and more generally speaking, with the entire Islamic countries."
"Our efforts have always been focused on further expansion of such ties with each and every one of them," the Iranian foreign minister concluded.
