Iran said on Wednesday that it would resist any plan to restrain its oil output as fellow Opec ministers flew to Tehran to try to persuade the country to join the first global oil pact in 15 years.The talks in Tehran follow a deal reached on Tuesday by dominant Opec power Saudi Arabia and non-Opec Russia, the world’s top two producers and exporters, to freeze production at January levels if other big oil nations also agree to join.Opec Gulf producers — Qatar, Kuwait and the UAE — as well as Vene-zuela said they would join the pact, aimed at tackling a growing oversupply and helping prices recover from their lowest in over a decade.But Iran is the major obstacle to the first joint Opec and non-Opec deal since 2001, as it has pledged to steeply increase output in the coming months, seeking to rubber seal for sale regain market share lost after years of sanctions.

　　"Asking Iran to freeze its oil production level is illogical when Iran was under sanctions, some countries raised their output and they caused the drop in oil prices." Iran’s Opec envoy, Mehdi Asali, was quoted as saying by the Shargh daily newspaper on Wednesday."How can they expect Iran to cooperate now and pay the price " he said. "We have repeatedly said that Iran will increase its crude output until reaching the pre-sanctions production level."The freeze plan has so far failed to push up oil prices, due to concerns Iran would not participate and that a deal would do little to ease the global glut as it would still allow Russia and Saudi Arabia to keep pumping at near record levels.
