President of Iran's Strategic Council Kamal Kharrazi said after the end of the 60-day moratorium to the three European Union countries Iran will take serious strides, adding that the Iranian officials are serious in their decisions.
Speaking to reporters after his meeting with the UK Deputy Secretary of Foreign and Commonwealth Office, Kharrazi said the UK official's trip was made in line with following up the two countries' relations.
Elaborating on Iran's acts after the end of the 60-day moratorium, he said the three European countries and the UK did not take serious actions in the Joint Comprehensive Plan of Action (JCPOA), so Iran will stop some of its commitments based on the JCPOA text.
The UK Deputy Secretary of Foreign and Commonwealth Office announced that the Instrument in Support of Trade Exchanges (INSTEX) will be implemented soon and London will support Iran deal and Iran has its problems with the US.
In response to the Islamic Republic News Agency (IRNA) reporter's question on Europe's commitments under the JCPOA and the future of the deal, Kharrazi said, "We are waiting to see what measure Europe will take within two weeks.
He urged Europe to put sources in INSTEX to pave the way for establishing exchange between Iran and Europe.
He called on the Europe to preserve its independence against US pressures, adding that even Iran's debts for Chieftain tanks has not been returned to Iran.
Commenting on UK official's mission in Tehran, he said during the meeting we protested against accusing Iran of the attacks on the oil tankers in the Persian Gulf.
Elsewhere in his remarks, he urged the UK government to refrain from hasty decisions if it wants to reduce tensions.
