Foreign Minister Yoriko Kawaguchi held separate phone conversations Saturday with her Chinese and South Korean counterparts to reaffirm relations with the neighboring countries, a Foreign Ministry official said.

"As our country's relations with China are extremely important, (I hope) cooperation will be promoted in wide-ranging areas," Kawaguchi was quoted as saying to Chinese Foreign Minister Tang Jiaxuan.

Her remarks were made in the context of the 30th anniversary this year of normalized diplomatic relations between Japan and China.
