US Deputy Secretary of State Stephen Biegun has reaffirmed his country's continued commitment to the complete denuclearization of North Korea, the State Department said Friday.

Biegun, while meeting with top South Korean officials in Seoul, also confirmed the United States' commitment to coordinating its denuclearization efforts with South Korea.

"During his meetings with senior ROK officials in Seoul, Deputy Secretary Biegun expressed appreciation for the ROK's continued partnership in COVID-19 response, discussed how to ensure the US-ROK alliance is prepared to face the challenges of the next 70 years," the department said in a press release.

ROK stands for South Korea's official name, the Republic of Korea.

Biegun also "reaffirmed our commitment to continued coordination with the ROK to achieve the complete denuclearization of North Korea," it added.

The statement came at the end of Biegun's trip to Seoul, where he met with his South Korean counterparts, including First Vice Foreign Minister Choi Jong-kun.

He also met with Foreign Minister Kang Kyung-wha. (Yonhap)
