Washington announced its new anti-Russian sanctions over Moscow's alleged use of chemical weapons in Salisbury on August 8. The new sanctions include, in particular, a ban on supplies of dual-purpose electronic devices and components to Russia.
US government also threatened to impose another round of sanctions against Moscow that would include banning Russian carrier Aeroflot's flights to the US, limiting diplomatic ties and halting US exports, saying that the second wave of sanctions depends on Moscow's future policies.
Russia has repeatedly denied involvement in the Skripals case, pointing at the fact that London has neither provided evidence nor cooperated with Moscow in investigating the incident.
Russian Prime Minister Dmitry Medvedev said after US sanctions announcement that if some sort of ban on banking activities or currency ban was imposed on Russia — it would mean a declaration of economic war ant that Russia would have to respond to it "economically, politically or in any other way, if need be".
