The special mechanism created by the European Union for payments with Iran does not include the other parties to the Joint Comprehensive Plan of Action (JCPOA), said the diplomat who was speaking to Russian media 'Interfax' on condition of anonymity.
This mechanism is intended solely to defend the European companies against US anti-Iran sanctions, he added.
Russia and China are expected to take measures to defend their firms against US sanctions.
After Washington's May 8 exit from the historic Iran Deal the US gave 90 to 180 wind-down period to other countries before it starts re-imposing oil sanctions on Tehran on November 4.
Part of the US illegitimate sanctions were imposed on Iran on August 9.
US President Donald Trump also said he would reinstate the US nuclear sanctions on Iran and impose “the highest level” of economic bans on the Islamic Republic.
