World powers are already considering the lifting of the United Nations' sanctions against Iran, if the Islamic country is able to come up with a deal that will regulate its nuclear activity.

Reuters' exclusive report says,  Britain, China, France, Russia and the United States, which are the five permanent members of the U.N. Security Council, have begun talks about issuing a resolution that will remove the sanctions.

Germany and Iran are also included in the meetings.

Once Tehran is cleared of sanctions, it will become more difficult for Republican-dominated U.S. Congress to undermine the nuclear deal Iran is crafting with the U.S. and other powerful countries.

Currently, there are four U.N. resolutions that impose sanctions on Iran.

All in all, eight U.N.resolution prohibits Iran from building up its uranium deposit and perform any sensitive atomic project.

The resolutions also bar Iran from buying and selling atomic technology and anything related to ballistic missiles.

An arms embargo against Iran is also in place.

Iran sees the lifting of the sanctions as a crucial move.

The U.S. and the European Union have often used the sanctions as basis for justifying the enforcement of more penalties on Iran.

The talks on possible lifting of sanctions comes, after 47 Republican senators sent a letter to Iran leaders on Monday, warning that any deal that the Obama administration will sign with Iran can be discarded by his successor.

President Barack Obama is set to finish his second term on January, 2017.

Western diplomatic officials say, if the U.N.will hand down a resolution that will lift the sanctions against Iran, it can prevent possible future attempts by the Republicans in Capitol Hill to unravel the nuclear deal.

Iran and six global powers want to complete the nuclear deal before the end of this month.
