The country exported over 2.28 million barrels oil and over 330,000 barrels of natural-gas condensates per day in June, the Mehr news agency added, referring to the NIOC statistics.
According to the oil company, Washington's decision has not yet impacted the country’s oil exports.
The report echoes the statement made by Iranian Vice President Eshaq Jahangiri earlier in the day, vowing to boost oil sales, fighting against the US sanctions.
On May 8, US President Donald Trump announced his decision to withdraw from the 2015 Joint Comprehensive Plan of Action (JCPOA), which requires Tehran to maintain a peaceful nuclear program in exchange for sanctions relief. Washington also decided to re-introduce restrictive measures against the Islamic Republic. Other parties to the agreement have not supported the US decision.
