SEOUL, July 20 (Yonhap) -- In talks with the United States on Iran sanctions this week, South Korea accentuated two things: alliance spirit and the special situations it faces, Seoul's foreign ministry said Friday.

The government sent an inter-agency delegation, headed by Deputy Foreign Minister for Economic Affairs Yun Kang-hyeon, to Washington D.C. for consultations on the thorny issue.

It met with Francis Fannon, assistant secretary of state for the bureau of energy resources, and roughly a dozen other state and treasury department officials on Thursday (local time).

It was the second round of bilateral negotiations on Washington's decision to resume a wide web of sanctions against Tehran. The previous talks were held in Seoul in June.

The U.S. has pressed South Korea and some other nations to halt their oil imports from the OPEC member or face so-called secondary sanctions with the May announcement of its exit from the 2015 nuclear agreement with Iran, called the Joint Comprehensive Plan of Action. The 180-day grace period is to end on Nov. 4.

Seoul hopes for a conditional waiver, similar to a measure put in place under the Obama administration. At that time, South Korea significantly reduced its oil imports from Iran.

The Northeast Asian country is not an oil producer and more than 13 percent of its total oil purchases come from Iran.

What's especially crucial is condensate -- ultra light oil -- used for the production of various petrochemical goods. Iran's condensate is known for its high quality.

It's also important to maintain Iranian oil imports for the won-based settlement of bilateral trade transactions.

South Korean refiners put money into bank accounts here for oil imports from Iran, whose firms pay for the purchase of South Korean products through them.

The two-way trade volume totaled US$12 billion in 2017, with South Korea exporting $4 billion worth of products.

In the bargaining, Yun explained the government's basic stance of support for a peaceful resolution to the Iranian nuclear issue, said the Ministry of Foreign Affairs.

He also emphasized that South Korea should be granted a waiver to minimize the impact to its companies doing businesses with Iran, citing the special conditions facing them.

"He proposed that the governments of the two nations cooperate more closely on the basis of the alliance spirit," the ministry said.

Although the U.S. reiterated that it will be quite stringent in granting a waiver this time, it promised to consider South Korea's positions, added the ministry.

The two sides apparently plan to continue talks but no schedule has been set.
