The US has imposed further sanctions against Russia over the events in eastern Ukraine and Crimea. Washington's blacklist has been expanded to include 11 additional individuals and 15 companies. Francis Boyle from the University of Illinois College of Law, said “This is a deliberate provocation of the Obama administration against President Putin. I find it very difficult to understand how they could do that, considering that Putin played a very important role in getting the Iranian agreement. President Obama personally called him to thank him, he publicly praised him. We had hoped that this would lead to constructive engagement between the United States and Russia.”
