“The virus of sanctions and disloyalty is threatening the international safety and security more than coronavirus,” Shamkhani wrote on his twitter page on Saturday.
He referred to the US offer for cooperation and assistance to Iran in battle against the coronavirus, and said such a claim “can only be verified by the US implementation of its legal commitments under the nuclear deal”.
The United States, which has had no diplomatic ties with Iran since 1980, pulled out of a landmark nuclear deal with the country and reimposed crippling sanctions in 2018.
The US State Department said last week it had formally told Iran of the United States’ willingness to assist in unspecified ways through a message sent via Switzerland, which represents US interests in Tehran.
Iran's Foreign Ministry Spokesman Seyed Abbas Mousavi said last Monday, "We have had doubts and continue to have doubts about the intentions of Americans. If they had good intentions, they would not have publicized the aid first in the media with propagandist aims."
"We monitor the Americans' positions. We have already seen how much they acted against Iran and our capabilities and toward weakening the people, and those actions still continue," he added.
"We doubt the intentions of Americans, and do not count on these aids and are not ready to receive verbal aid either," Mousavi said.
