TOKYO (Reuters) – Iran has no intention of making or using nuclear weapons, Iranian Supreme Leader Ayatollah Ali Khamenei was quoted as saying on Thursday by Japanese Prime Minister Shinzo Abe.

Khamenei’s comment, a reiteration of Iran’s stance, comes at a time of increased U.S.-Iranian tension, a year after Washington abandoned an agreement between Iran and world powers to curb its nuclear program in exchange for the lifting of international financial sanctions.

“Supreme Leader Khamenei made a comment that the country will not and should not make, hold or use nuclear weapons, and that it has no such intentions,” Abe told reporters in Tehran following a meeting with Khamenei.

“Today, I met Supreme Leader Khamenei and heard his belief in peace. I regard this highly as a major progress toward this region’s peace and stability,” said Abe, the first-ever Japanese prime minister to hold talks with Khamenei.

Abe’s comment was broadcast on Japanese public broadcaster NHK.

On Wednesday, Abe warned of unintended clashes in the crisis-hit Middle East after meeting Iranian President Hassan Rouhani.

Abe was visiting Iran to help ease rising tension between the United States and the Islamic Republic.

Japan is in a unique position to act as a mediator as the U.S. ally has long maintained close ties with Iran.
