Seoul, Oct 19 (IANS): The intelligence chiefs of South Korea, the US and Japan met here on Tuesday and discussed North Korea's firing of what appeared to be a submarine-launched ballistic missile (SLBM) toward the East Sea earlier in the day, Seoul's state spy agency said.

On Tuesday morning, North Korea fired the short-range missile from the vicinity of Sinpo, where its main submarine shipyard is located, according to the South Korean military.

It marked the North's eighth known major missile test this year, Yonhap News Agency reported.

The North's latest show of force came as Avril Haines, the US director of national intelligence, and Hiroaki Takizawa, Japan's Cabinet intelligence director, were in Seoul for trilateral talks with Park Jie-won, the head of South Korea's National Intelligence Service.

"During the meeting, they had a candid conversation on issues of common interest, including the security situation surrounding the Korean Peninsula," the spy agency said in a statement.

"The top intel officials also shared information on North Korea's short-range missile launch and assessed the situation."

On Monday, Park held bilateral talks with his US and Japanese counterparts.

The firing came amid a flurry of diplomatic activities to resume the long-stalled denuclearization talks, with top nuclear envoys of South Korea, the US and Japan in Washington to discuss ways for the resumption of dialogue.

During Tuesday's meeting, the three intel chiefs also discussed economic security issues, such as the global supply chain disruptions and tech leakage, and vowed to strengthen their trilateral intelligence cooperation, according to the agency.

The trilateral meeting also drew attention to Tokyo's new policy direction on North Korea, as Takizawa's Seoul visit was his first since Japan's new Prime Minister Fumio Kishida took office earlier this month.

The three last held such a trilateral meeting in May in Tokyo.
