Feng made the remarks Saturday in an exclusive interview with the Islamic Republic News Agency (IRNA).
China will continue economic and trade ties with Iran, he said adding that US withdrawal from Iran nuclear deal will have no effect on economic relations between the two countries.
China is against economic unilateralism of US or any other country and its domestic regulations are not important for China.
'We are against US withdrawal from Iran deal known as the Joint Comprehensive Plan of Action (JCPOA) and Washington's possible unilateral sanctions against Tehran,' he added.
Promoting economic relations between Iran and China does not run counter to international regulations, he said adding that both countries will continue ties in the future.
The value of Iran-China trade stood at about $ 37.3 billion in 2017 which showed a %19.3 growth compared to the same period in 2016, Feng said.
He went on to say that China is Iran’s first trade partner, adding that both countries have preserved their relations in one decade in such a way that China is the biggest buyer of Iranian crude oil and customer of Iran's non-oil commodities.
