Erdogan Defies Trump Over Iran Sanctions Dorian Jones ISTANBUL - Turkish President Recep Tayyip Erdogan on Friday continued to chart a collision course with Washington over Iran. Erdogan is categorically ruling out enforcing American sanctions intended to put Iran in an economic straitjacket. "It is impossible for us to cancel relations with Iran with regard to oil and natural gas. We will continue to buy our natural gas from there," Erdogan said to reporters Friday, while returning from the United Nations General Assembly. Turkey is Iran's second-largest importer of natural gas. "The importance [of] this announcement is economic," said Iran expert Jamshid Assadi of France's Burgundy Business School. "Any income in Tehran's situation is very welcome by the regime, which is increasingly starved of funds." .
