Trump administration considering more aggressive enforcement of its sanctions on Iran - WSJ

Citing U.S. officials familiar with the matter, The Wall Street Journal reported that the Trump administration was planning to introduce new sanctions on financial institutions that do business with Iran in an attempt to further limit the amount of US dollars flowing into the country. 

"The new sanctions on banks and businesses would be aimed at choking off trade ranging from Iran's petrochemical sales to Singapore to its consumer good sales to Afghanistan," wrote The WSJ's Benoit Faucon and Ian Talley.
