SEOUL, Dec. 5 (Yonhap) -- South Korea and the United States had working-level discussions this week on technical issues related to a sanctions waiver on Iranian oil imports, the Ministry of Foreign Affairs said Wednesday.

Last month, South Korea was granted the exemption by its ally, allowing it to continue to purchase Iranian oil, although the volume will be reduced significantly.

The two sides had talks to follow up on the measure in Washington D.C. on Tuesday (local time), according to the ministry.

South Korea's inter-agency delegation was led by Hong Jin-wook, director general of the ministry's African and Middle Eastern Affairs bureau. His counterpart was David Peyman, deputy assistant secretary of state for counter threat finance and sanctions.

They discussed "technical issues, including finance, shipment and insurance to support transactions of the trade sector," the ministry said.

Hong requested the U.S. offer "clear guidelines" on specific targets of Iran sanctions as swiftly as possible, citing a possible gray area.

Peyman agreed to work closely with South Korea via diplomatic channels.

The South Korean team also included representatives from the finance ministry, the trade ministry and the Financial Services Commission.
