Western Nations have been continuously complaining about Iran undertaking many nuclear projects in order to make nuclear weapons.
However, Iran refuses this outright and insisted that it will use the nuclear projects only for constructive purposes such as electric power generation, etc for the public betterment and welfare.
Still, countries like USA, England, China, Russia, France, and Germany refused to accept this explanation and imposed many economic & commercial restriction on Iran.
Later, there was a meeting held at Vienna, capital of Austria, between Iran and these countries and an agreement was reached.
Following this, the sanctions and restrictions imposed by these countries will be gradually withdrawn.
Central Petroleum Minister Mr. Dharmendra Pradhan commented on this development that it is expected that the prices of crude oil are likely to fall following the withdrawal of sanctions on Iran. Hence, there are bright prospects for reduction in the prices of petrol & diesel.
