Iran on Sunday claimed to have found a new oil field that would boost its supply by a third — delivering the news with a shot at US sanctions.

“I am telling the White House that in the days when you sanctioned the sale of Iranian oil and pressured our nation, the country’s dear workers and engineers were able to discover 53 billion barrels of oil in a big field,” Iran’s president, Hassan Rouhani, said in a public announcement.

Rouhani said the field was located in Iran’s southern Khuzestan province, home to its crucial oil industry, with the 53 billion barrels added to Iran’s reserves of roughly 150 billion.

“This is a small gift by the government to the people of Iran,” he said in a speech from the central city of Yazd, according to Agence France-Presse.

“We announce to America today that we are a rich nation, and despite your enmity and cruel sanctions, Iranian oil industry workers and engineers discovered this great oil field.”

Since the U.S. withdrew from the 2015 nuclear agreement, the other countries involved — Germany, France, Britain, Russia and China — have been struggling to save it, but have offered no opportunities for Iran to sell its oil abroad.

Company or governments that buy Iran’s oil face harsh U.S. sanctions.

The collapse of the nuclear deal coincided with a summer of mysterious attacks on oil tankers and Saudi oil facilities that the US blamed on Iran. Tehran denied being responsible, but did seize oil tankers and shoot down a US military surveillance drone.
