Sept. 14 (UPI) -- The United States' second-most senior diplomat expressed regret Sunday over the recent immigration raid at a Hyundai car battery plant in Georgia.

U.S. Deputy Secretary of State Christopher Landau met Sunday with First Vice Minister of Foreign Affairs Park Yoon-joo to discuss cooperation in the continued efforts to resolve the diplomatic spat stemming from the raid, South Korea's Foreign Ministry said in a statement.

During the meeting, Park highlighted the "uncomfortable treatment" faced by hundreds of South Korean nationals who were detained and deported after the raid and the shock felt across the country at the incident.

"Deputy Secretary Landau expressed deep regret over the incident and proposed using it as a turning point to improve the [visa] system and strengthen the [Republic of Korea-United States] relationship," the foreign ministry said. Landau was also said to have recognized the significant contributions and investments made by Korean companies for the "revitalization of the U.S. economy and manufacturing industry."
