The Iranian council known as the Expediency Council approved an anti-money laundering bill to ease trade.
This bill will be in line with the standards set by the Financial Action Task Force (FATF).
It is considered a major step towards reforms that would bring Iran into line with global norms and could facilitate foreign trade in the face of U.S sanctions.
The FATF is an inter-governmental organisation that underpins the fight against money laundering and terrorist financing.
Iran is alone with North Korea on the FATF’s blacklist.
