Iran Denies Airplane Refueling Problems Due to Sanctions VOA News 06 July 2010 Iran's Foreign Ministry has denied claims that international airports are refusing to refuel Iranian planes because of sanctions. A Foreign Ministry spokesman, Ramin Mehmanparast, said there have been no fuel limitations on Iranian planes since the United States implemented new sanctions against Iran last week. The Iranian news agency ISNA quoted a top airline official Monday as saying airports in Britain, Germany and the United Arab Emirates had refused fuel for Iranian planes. Officials in Britain, Germany and the UAE denied knowledge of any refueling ban, but a source in the UAE said a private firm had refused to refuel an Iranian plane there.  Meanwhile, China denounced the United States Tuesday for expanding on the latest U.N. sanctions imposed on Iran. A Chinese Foreign Ministry spokesman, Qin Gang, said China supports the U.N. sanctions, but believes countries should focus on implementing these instead of adding more as the United States did last week. Iran continues to dismiss the economic impact of the U.S. sanctions, which target Iran's energy and banking sectors. President Mahmoud Ahmadinejad said Monday that Iran's people will prove the sanctions to be a failure.  Oil Minister Massoud Mir-Kazemi said the sanctions are "nothing new" and would not affect Iran's energy sector. The U.S. sanctions aim to make it harder for Iran's government to buy refined petroleum. The sanctions also exclude from U.S. markets companies involved in selling gasoline, jet fuel and other such products to Iran. U.S. President Barack Obama said the new sanctions will strike "at the heart" of Iran's ability to fund and develop its alleged nuclear weapons program. Iran says its nuclear program is peaceful, but Western nations suspect Iran is trying to build atomic weapons. Some information for this report was provided by AP and Reuters. .
