This is due to the imminent expiration of the UN arms embargo.
US President Donald Trump plans to issue an executive order allowing him to impose sanctions on anyone who violates the arms embargo against Iran, four anonymous sources close to the situation said.
According to sources, a presidential decree is expected in the coming days, which will punish violators with secondary sanctions, depriving them of access to the American market.
The decision is because the UN arms embargo on Iran will soon expire. Also, Washington wants to warn foreign players that if they violate the embargo, they will face sanctions from the United States.
