DAVOS, Switzerland -- Iranian President Hassan Rouhani has called for free and fair elections in Syria, saying it would respect any outcome.
Rouhani also said his nation is "ready to engage" with its neighbors on most important issues of the day.
Rouhani says "the best solution is to organize a free and fair elections in Syria" and that once the ballots are cast "we should all accept" the outcome. Iran was barred from participating in the Swiss-based talks to end Syria's civil war.
He told the World Economic Forum in Davos on Thursday that his country wants to deepen relations, notably trade, with its neighbors and that relations with Europe will be "normalized."
Iran is the regional heavyweight that
few want at the negotiating table, but without it any attempt to end the Syria war may be futile. Iran's backing is crucial for President Bashar

The absence of Damascus' strongest regional ally stood out even more given that the biggest supporters of the opposition were all present: Saudi Arabia, Qatar and Turkey.
The question of Iran's participation underlines how the international powers that have lined up behind either Assad or the rebels trying to topple him are as crucial to a solution as Syria's warring parties themselves.
Like any of the regional players, Iran can be a spoiler for a resolution it opposes or can be a force for pressuring its side to make concessions.
"The decision to exclude Iran from the Montreux talks is a huge diplomatic mistake," said David Cortright, director of policy studies at the Kroc Institute for International Peace Studies.
"As a major backer of the current regime, Iran has enormous potential leverage in Damascus," he said.
Syria's 3-year-old conflict is locked into a brutal, bloody deadlock - which in many ways favors Assad's government. Neither side has been able to militarily overwhelm the other, but Assad's forces have gained some momentum, and his government and military have remained cohesive, while rebels have fallen into infighting between Islamic extremist and more moderate factions.
The military dynamic on the ground has given Assad little reason to allow the creation of a transitional government in which he is not a part - and which the U.S. and the opposition says is the peace conference's goal.
But the fight is also a proxy war, with the influence of international powers enabling both sides to dig in.
Shiite-led Iran has poured money into keeping Assad's government afloat financially, has supplied it with weapons and has backed the intervention of fighters from Lebanon's Shiite guerrilla force Hezbollah and from Iraq's Shiite militias on the side of the Syrian military. Tehran is adamant in ensuring the survival of its vital ally that gives it influence squarely in the center of the Arab world. Meanwhile, Russia, a longtime ally of Syria, has provided Damascus important diplomatic cover, blocking several resolutions against it at the U.N. Security Council.
On the other side, Sunni Arab nations
in the Gulf - particularly Saudi Arabia and Qatar - as well as the United
States have thrown their backing behind the rebellion, trying to stem the
influence of their rival Iran.
The Syrian ambassador to the U.N., Bashar Jaafari, said the 40 countries present Wednesday were "seemingly pre-selected" and represent governments hostile to Damascus. Foreign Minister Walid al-Moallem called Tehran's exclusion a "big mistake," saying that "it is not possible to ignore Iran's important role in bringing stability to the region."
Asked about the subject at a press conference following the talks Wednesday, U.S. Secretary of State John Kerry acknowledged Iran's ability to "make a difference" but reiterated that it has yet to accept the basis for the talks, which is the establishment of a transitional governing body for Syria.
The United States, Saudi Arabia and the opposition say that government cannot include Assad - a stance Damascus, firmly rejects.
"There are plenty of ways that that door can be open in the next weeks and months and my hope is that they will want to join in a constructive solution," Kerry said.
Cortright said that Tehran could eventually come around to a Syrian government without Assad, if it addresses their needs.
"Iran's goal in neighboring Syria is to have a regime that is friendly to its interests and that protects the Alawite community," he said, referring to the Shiite offshoot sect to which Assad belongs. "But this does not mean Iranian officials are wedded to the discredited Assad regime."
He said that by inviting Saudi Arabia and excluding Iran, "the United States is taking sides in a regional ethnic power struggle. This could exacerbate the deepening Sunni-Shiite divide and further undermine security in the region."
But reaching a stage that could lead to Assad not holding power is likely to be very far down the line.
"We have to be very realistic, the conference won't lead to a political settlement or an end to the conflict," said Ayham Kamel, a London-based Mideast analyst for the political risk assessment Eurasia Group. After the failure of the attempt to remove him by force, "now we are in a different world where an Assad ouster is no longer realistic in the near term."
Instead, he said the aim should be to bring democratic reforms in Syria that reduce the grip on power of Assad and his leadership, paving the way eventually for a post-Assad Syria - and that both Iran and Russia are key to that.
"If you needed a final agreement that included real concessions and eventually finds an avenue for Assad to leave - definitely not in the near term - it would require Iranian and Russian support," he said.
Swedish Foreign minister Carl Bildt, who previously served as a top U.N. official on the post-war Balkans, said negotiations should include anyone with a significant role in the conflict.
"You make peace between enemies, you don't have a peace conference to make peace between friends," Bildt said. "So everyone that should have any sort of relevance should be around the table."
