South Korean Defense Minister Suh Wook on Thursday emphasized the need for close defense cooperation with China and Japan to maintain peace and stability on the Korean Peninsula and the region, the defense ministry said.

"While the alliance between South Korea and the United States remains strong, I think (Seoul should) closely cooperate and get along with neighboring China," Suh said during a lecture in Singapore. 

China can play a key role in the denuclearization of the Korean Peninsula and is a crucial economic partner for South Korea, he added.

He gave the lecture at S. Rajaratnam School of International Studies of Nanyang Technological University after his talks with Singaporean Defense Minister Ng Eng Hen.

The minister said while the strategic competition between Washington and Beijing has an adverse impact on the security situation on the peninsula, the two powers can also cooperate in the process of peacefully resolving Korea issues.

Suh also said South Korea needs to promote exchanges with Japan. 

"Despite differences on pending issues, we believe close cooperation (between the two countries) is needed for peace and stability in the region," he said.

Seoul will continue to push for dialogue and defense cooperation with Japan, he added.

Earlier in the day, Suh and Ng Eng Hen discussed regional security cooperation, including joint efforts to fight terrorism.

Suh used the talks to reiterate South Korea's desire to deepen defense cooperation with the Association of Southeast Asian Nations, the ministry said. (Yonhap)
