The United States has called up on Egypt not to engage in business with Iran after the two nations agreed to allow direct flights for the first time in the last 30 years, reports said on Thursday.
Cairo and Tehran reached a preliminary deal to resume direct flights with 28 departures per week. However, no deadline was set for resumption of air links.
State Department spokesman Mark Toner said in Washington that all nations intending to start trade ties with Iran should first ensure that the Islamic Republic fulfills its nuclear obligations.
"We continue to urge all countries - including Egypt - not to pursue any new business deals until Iran complies with its international obligations," said Toner.
