TEHRAN, Oct. 28 (Xinhua) - Visiting Turkish Prime Minister Recep Tayyip Erdogan on Wednesday expressed his supports for Iran' s right to peaceful nuclear energy attainment. Turkey is against nuclear weapons, but all the countries including Turkey and Iran has the right to use nuclear power for humanitarian purposes, said Erdogan in a Press conference in Tehran. As with Turkey's role in Iran's nuclear standoff, Turkey's prime minister pointed out that he does not act as a mediator between Iran and the United States. He also stressed that Iran plays an important role in the regional peace and stability. Asked about his recent reportedly anti-Israel moves, he said that Turkey's positions on international issues are in accordance with the international interests and it does not mean that those positions are against Western countries. Turkey has good relations with both the West and the East, he added. Erdogan who arrived in Tehran on Monday for a two-day official visit, met some Iranian high ranking officials and both sides exchanged views on the issues of mutual interest. Iran and Turkey expressed their willingness to enhance bilateral trade exchange to some 30 billion U.S. dollars within the coming four or five years. The further details about the talks have not been disclosed yet.
