Turkish Prime Minister Tayyip Erdogan arrived in Tehran Wednesday for a two-day visit, to discuss nuclear policy and regional politics.

At the top on the agenda of the talks between Erdogan and Iranian President Mahmoud Ahmadinejad would be the next meeting between Iran and six other countries about its nuclear program and the latest developments in Syria.

Erdogan, accompanied by his foreign minister, Ahmet Davutoglu, was also scheduled to open a Turkish cultural centre in Iran.

Istanbul has declared its readiness to again host the nuclear talks between Iran and Britain, China, France, Germany, Russia and the United States, which are reportedly scheduled for mid-April.

Turkey hosted similar talks in January 2011.

Erdogan was expected to brief Ahmadinejad on the expectations of the six countries from both Iran and the next nuclear talks and the probable consequences of a renewed failure of the negotiations.

The talks focus on international fears that Iran has not come clean about its nuclear program and is using it to develop weapons, but Iran insists that it is only for energy production and medical purposes.

Syria would also be a delicate issue during Erdogan's visit as Ahmadinejad supports the government of President Bashar al-Assad and Erdogan the Syrian opposition.
