Iran launched its first freight train intended for export from the city of Qom to China. Meanwhile, 460 tons of sodium chlorate were shipped by train from Semnan province to Turkey, as Tehran seeks to expand its export routes. Against the backdrop of increasing restrictions on maritime transport, the volume of rail transport from China to Iran has increased tenfold, and the frequency of arrival of Chinese trains to Iran has increased from once every three to four days to once a day, Fars News reported.
