President Barack Obama has signed the corresponding order, Reuters reports.
Russian and Crimean officials as well as ordinary citizens and organizations destabilizing the situation in Ukraine will be affected by the sanctions.
The names of the officials on the list are not available now, lenta.ru reports. The USA is ready to make further steps depending on the situation in Ukraine, Obama’s Administration said.
The USA and European Union threatened Russia with economic sanctions earlier: they are accusing Moscow of interfering into Ukrainian domestic issues. However, such measures will only be taken if Russia brings troops into Ukraine, Washington and Brussels announced.
