LEVERAGES FOR BARGAIN, WINING TIME FOR DIPLOMATIC BREAKTHROUGH

The West sees the latest development of Tehran's atomic program as defiant steps to further violate its obligation, but analysts said Iran might be still winning time and space for a diplomatic breakthrough as well as using these progress as leverages to gain a better position in the talks with the world six powers, asking the West to dismantle the sanction, which hurts the country's economy by blocking its oil export channel, Iran's lifeblood.

Iran's crude oil exports in March may plunge by a quarter from a month earlier to the lowest since tight sanctions came into effect in 2012, industry sources said, squeezing income for Tehran as sanctions cast doubt over its future revenues.

On the other side, the western policy makers have embarked on a crippling and engaging policy toward Iran, which is aimed to curb Iran's nuclear activities by using composite measure.

In the latest talks in Almaty, the relief of the sanctions is also used as leverage by the West for a bargain, and a new proposal was put on the table, which demand Iran to scale back its uranium enrichment, especially the 20 percent uranium production, in return for the relief of the sanctions.

Iran's Supreme Leader Ayatollah Ali Khamenei said Thursday the next round of talks between the world powers and the Islamic republic over the latter's nuclear program will be a test for the West's sincerity, semi-official Fars news agency reported.

In Almaty, the Western countries did not do something important, rather, they admitted a small part of the Iranian nation's rights, said Khamenei without elaboration.

Both sides now are holding stakes to make the bargain, making the talks tougher.
