The foreign ministry on Saturday welcomed the United States and Japan's recent summit meeting where the leaders of the two countries reaffirmed their commitment to the complete denuclearization of North Korea.

On Friday (Washington time), U.S. President Donald Trump and Japanese Prime Minister Shigeru Ishiba also expressed concerns over the North's advancing weapons programs and underscored the importance of trilateral cooperation with South Korea during their first in-person summit.

"The views of the U.S. and Japan announced at the summit regarding the Korean Peninsula, including countering North Korea's illegal cyber activities and military cooperation with Russia and seeking dialogue with North Korea based on trilateral cooperation, align with our policy direction, which has been continuously conveyed to the U.S. through various channels at all levels," the ministry said.

Seoul will continue its diplomatic efforts for the complete denuclearization of North Korea based on close trilateral cooperation with Washington and Tokyo, it added.

Friday's summit took place amid expectations for the potential resumption of Trump's personal diplomacy with North Korean leader Kim Jong-un. (Yonhap)
