Japan, US, and South Korea Strengthen Defense Ties Amid China’s Assertiveness

On July 28, Japan, the US, and South Korea signed a memorandum in Tokyo to enhance their trilateral defense cooperation. This agreement aims to sustain policy consultations, information-sharing, and joint exercises amidst China’s assertiveness in the East and South China seas.

Historic Meeting

This meeting was the first of its kind in 15 years and follows a landmark summit held by US President Joe Biden at Camp David nearly a year ago. The defense chiefs of the three nations—US Defense Secretary Lloyd Austin, Japanese Defense Minister Minoru Kihara, and South Korean Defense Minister Shin Won Sik—vowed to strengthen cooperation to deter nuclear and missile threats from North Korea.

Joint Statement

In a joint statement, the leaders reaffirmed the unwavering nature of their new era of trilateral cooperation. Japanese Defense Minister Minoru Kihara stated, “By signing this memorandum, our trilateral cooperation has become more solidified and will not waver, even under changes in international circumstances.”

Opposition to Unilateral Changes

The leaders also reaffirmed their strong opposition to any unilateral attempts to change the status quo in the waters of the Indo-Pacific, with China’s forceful stance in mind. Tensions have been high over China’s maritime claims in the South China Sea and repeated intrusions into Japanese territorial waters around the Senkaku Islands.

Institutionalizing Cooperation

Kihara, Austin, and Shin had agreed to institutionalize trilateral security cooperation during their last meeting in June in Singapore. In June, the three nations conducted a new annual joint military exercise called “Freedom Edge,” covering aerial, naval, and cyber domains in areas including the East China Sea.

US-Japan Defense Cooperation

Yesterday in Tokyo, US Defense Secretary Austin, US Secretary of State Antony Blinken, and their Japanese counterparts Minoru Kihara and Yoko Kamikawa met to deepen US-Japan defense cooperation. They termed China’s political, economic, and military coercion as the greatest strategic challenge in the Asia-Pacific region and beyond.

Austin announced that US forces in Japan would be reconstituted as a joint force headquarters reporting to the Commander of US Indo-Pacific Command, marking the most significant change to US Forces Japan in 70 years.
