TEHRAN, May 6 (UPI) -- Chinese companies are still welcome in Iran's energy sector, but those not meeting their obligations are a source of frustration, the oil minister said Tuesday.
Iranian Oil Minister Bijan Zanganeh last week said a contract with China National Petroleum Corp. for development of the South Azadegan oil field was torn up because the company wasn't meeting Iran's expectations at a field said to hold more than 40 billion barrels of oil.
