Iran cancels $2B dam deal with China

Iran has cancelled a $2 billion contract for a Chinese firm to help build a hydroelectric dam in the country, Chinese state media said on Thursday, a move that risks upsetting Beijing, one of Tehran's most important economic and political allies.

Iranian President Mahmoud Ahmadinejad is due to visit China next week for a security summit, where he is expected to hold talks with his Chinese counterpart, Hu Jintao, on Iran's disputed nuclear program. (Reuters)
