This was announced by White House Press Secretary Josh Earnest at a Monday briefing, Censor.NET reports citing Interfax.
The set of measures available to the United States includes sanctions that have proven to be an effective and powerful tool, Earnest said answering a reporter's question about the possibility of imposing additional restrictions against Russia in connection with the situation around Aleppo.
According to him, President Barack Obama is considering various measures, and his national security advisers regularly provide him with all the latest information on available options. Given the fact the United States is no longer involved in talks with Russia on Syria, this topic is going to be raised more often in the following days, Earnest added.
As previously reported, in 2014, the European Union, the United States and several other countries imposed sanctions against Russia in connection with the occupation of Crimea and aggression in eastern Ukraine. These restrictive measures were repeatedly extended and expanded. In particular, the talks on visa waiver and a new basic agreement on cooperation were suspended; several Russia's officials were banned to travel to the EU while their assets were attached. Trade, financial, and military restrictions were introduced.
The sanctions list included a total of 151 individuals and 37 entities. The sectoral sanctions were imposed against 20 Russian financial, oil-producing and defense companies.
The Russian Federation introduced a package of retaliation restrictions against the EU, the U.S., Australia, Canada, and Norway in August 2014. The so-called counter-sanctions prohibited imports of fruit, vegetables, as well as dairy and meat products to Russia from these countries for a one-year period.
