Japan says it is pressing the US for exemptions from new sanctions to continue oil imports from Iran.

"In any case, the government intends to have talks with the US tenaciously in order to continue Iranian crude oil imports," Minister of Economy, Trade and Industry (METI) Hiroshige Seko said.

Japanese officials have said they need Iranian oil and have cited exemption from US sanctions as among their highest priorities for the country’s energy industry.

Refiners have rushed to take cargoes before US sanctions come into effect in November. In July, Japan lifted more than 183,000 barrels per day of Iranian oil, raising imports for the third consecutive month year on year.

According to METI data released Friday, Iran was Japan’s fifth largest crude supplier in July, accounting for 6.3% of imports.

Japanese refiners, however, are worried about punitive US measures if they maintain their Iranian oil imports and expecting guidance from the government.

Seko, however, said the country’s refiners need to make their own decisions as to whether import oil from Iran.

Japan's METI Minister Seko addresses the closing dinner at the Business Round Table (BRT) annual meeting with the EU in 2017.

Platts quoted an Idemitsu Kosan spokesman as saying that the refiner has yet to decide on its Iranian oil policy. The company, he said, is still carefully monitoring the progress of the bilateral talks between Japan and the US.

Cosmo Oil also said it has yet to make a final decision on its Iranian crude oil policy but it does not plan to load any crude oil from Iran in October.

The sanctions specifically targeting Iran's oil industry take effect Nov. 4. President Donald Trump has said the US wanted to bring Iran’s oil exports down to zero.

Iranian President Hassan Rouhani has warned that no oil would pass through the Strait of Hormuz in the Persian Gulf if Iranian exports were blocked.

Washington is trying to stop Iran’s petrochemical, steel and copper exports, and to disrupt its ports and shipping services.

Rouhani said on Tuesday Iran is facing a "psychological and economic war in which oil, gas and petrochemical industries are at the forefront of confronting the ill-wishers."

"At the forefront of this war are the sectors that bear the burden of the economy, of which most important are oil, gas and petrochemicals, because when the enemy wants to boycott us, it pinpoints oil, gas and petrochemicals," he said.

Moving Kharg terminal to Jask

Rouhani said Iran has started moving its main export terminal in Kharg on the Persian Gulf to Jask in the Sea of Oman.

Speaking during the inauguration of three petrochemical projects, Rouhani said Iran must streamline oil shipments and use terminals outside the Persian Gulf.

“This is very important for me and a strategic issue. A large part of our oil sales should be moved from Kharg to Jask and the work has started and God willing, it will be completed in the twelfth government,” he said, referring to his tenure.

The Strait of Hormuz, which sits at the mouth of the Persian Gulf, provides the only maritime passage from the Persian Gulf to open seas.

The waterway is a strategic artery linking Middle East crude producers to key markets in Asia Pacific, Europe, North America and beyond, through which a third of the world's sea-borne oil passes every day.
