The ambassador stressed that the ties were still intact at a meeting with Deputy Chairman of Tehran Chamber of Commerce, Industries, Mines and Agriculture (TCCIMA) for International Affairs Mohammad-Reza Bakhtiari, the Iranian media reported.
"The fact is that South Korean companies are interested in working in Iran and want to continue their trade and business cooperation with Iran. Of course, the problem of unilateral sanctions imposed by the US on Iran should be taken into consideration," the ambassador said, as quoted by the outlet.
The South Korean diplomat added that the companies were "seeking waivers from US sanction… to continue oil purchase" from Iran.
In May, US President Donald Trump said Washington would withdraw from Iran nuclear deal, reinstating sanctions against Tehran.
