(ATTN: UPDATES with South Korean foreign ministry statement in paras 4-5, 8-9)
WASHINGTON, Dec. 6 (Yonhap) -- The top diplomats of South Korea and the United States met in Washington Thursday and agreed to coordinate closely in their efforts to denuclearize North Korea, both sides said.
South Korean Foreign Minister Kang Kyung-wha and U.S. Secretary of State Mike Pompeo held their first meeting in two months amid an impasse in denuclearization negotiations between Washington and Pyongyang.
The diplomats "reaffirmed the ironclad alliance between the United States and the Republic of Korea," State Department spokeswoman Heather Nauert said in a statement, "and pledged to maintain close coordination to ensure the final, fully verified denuclearization of the Democratic People's Republic of Korea."
South Korea's foreign ministry said the two exchanged "in-depth views" on ongoing talks between Washington and Pyongyang, and progress in inter-Korean ties.
While reaffirming the importance of maintaining sanctions on the North, they also agreed to continue to work together for complete denuclearization and lasting peace on the Korean Peninsula, the ministry said in a statement.
The allies have sought to coordinate their policies on North Korea as the South pushes to expand cross-border ties to facilitate Pyongyang's denuclearization, and the U.S. remains wary of action that could undermine sanctions imposed on the North for its nuclear and ballistic missile programs.
Kang was in Washington as the head of a South Korean government delegation to Wednesday's funeral of former U.S. President George H.W. Bush.
The ministry said she and Pompeo also committed to encourage their respective negotiating teams to come up with a mutually satisfactory agreement on renewing a cost-sharing deal tied to the stationing of some 28,000 U.S. troops in South Korea.
U.S. forces have been deployed to the South to deter North Korean aggression since the 1950-53 Korean War ended with an armistice, not a peace treaty.
