Iran's President Hassan Rouhani, after securing a decisive re-election, has pledged to open the country to the world and deliver freedom its people have yearned for.
Raisi, his main rival, accused him during the campaign of being unable to cash in the benefits that the nuclear deal has brought.
"Iran's nation chose the path of interaction with the world, away from violence and extremism", the 68-year-old reformist said in a televised speech on Saturday.
Iran´s newly re-elected President Hassan Rouhani on Monday dismissed his United States counterpart Donald Trump´s summit with Arab leaders in Saudi Arabia this weekend as "just a show".
The Trump administration's national security officials are on record as considering Iran the source of most of the Middle East's troubles, and the Republican-controlled U.S. Congress has been resistant to loosening the unilateral sanctions that are frightening off foreign banks and businesses from investing in Iran.
President Zuma said South Africa looks forward to working with Iran under President Rouhani to consolidate relations and implement existing agreements. At one point, Supreme Leader Ayatollah Ali Khamenei called rhetoric in a TV debate "unworthy". His defeat leaves the conservatives without an obvious flag bearer. The final deal means that Iran has committed itself to only using its nuclear programme for peaceful purposes. They had thrown their support behind Raisi to safeguard their interests.
Despite coming out of the blue to challenge incumbent Rouhani, it seemed for a while that Raisi was gaining enough momentum to win an election.

"It is even a stretch to call this an election in any conventional sense when all the contestants were hand-picked by the Supreme Leader, when outsiders were not permitted to observe the process, and when minority candidates were excluded from the polls".
In the wake of his re-election, business leaders cautioned that Mr. Rouhani will face an uphill battle as he works to expand Iran's economy.
"We won. We've done what we should have for our country. Who can say the region will experience total stability without Iran?" he said at a news conference.
Videos on social media showed huge crowds out on the streets across Iran.
"The next president should not be someone who makes the enemies happy when he is elected", said Kermani, who is an adviser to Khamenei.
This means an end to the nearly 15-year dominance of conservative councillors over Tehran's city council.
"Democracy in Iran is allowed to bloom only a few days every four years, while autocracy is evergreen".
Trump noted: "The Iranian regime's longest suffering victims are its own people".
Asked about Trump's summit with Arab leaders on Sunday, Rouhani said it was "just a show with no practical or political value of any kind".
But in a clear warning to Iran's "enemies" and in a nod to the conservatives, he added that the people of Iran "are not willing to accept any humiliation or threat".
But hard-liners still wield power in other ways in modern Iran.
