Bottom-Line Up Front:
1. Taiwan experienced 138 aerial and 61 naval incursions by the PLA.
2. The United States led air and naval maneuvers in the South China Sea. China responded by tailing the movements.
3. Coverage of a Brookings Institute webinar suggests Chinese naval manufacturing is unmatched globally. China is currently growing its navy to reach parity with the United States.
4. The U.S. and Japan concluded exercise Resolute Dragon 24. The bilateral exercise took place across Japan, and included the deployment of an advanced radar to an island near Taiwan.

Joint Drills In South China Sea Prompt Chinese Response
On 7 August, the United States, Australia, Canada, and the Philippines conducted air and naval maneuvers in the South China Sea. The maneuvers were designed to promote joint cooperation and uphold international maritime law.
Shortly after the maneuvers began, China’s People’s Liberation Army (PLA) also conducted maritime patrols. The Filipino military stated that three Chinese vessels tailed the allied maneuvers.
Why This Matters
In a joint statement on 7 August, the allied partners stated that they stand together to “address common maritime challenges” and their interest in “upholding international law and the rules-based order.”
China has claimed the South China Sea since the 1930s, but has been increasingly aggressive in asserting those claims.

Chinese Navy Manufacturing At Unmatched Rates
On 6 August, The Economic Times suggested that China’s naval manufacturing efforts are unmatched.
Center for a New American Security expert Tom Shugart used satellite imagery to determine China’s ongoing shipbuilding. In a 26 July webinar with the Brookings Institute, he cited the following projects:
Huludao Shipyard. Four or more Type 093B and Type 096 nuclear submarines being built.
Dalian Shipyard. Five Type 053DL destroyers being built.
Hudong Shipyard. Three frigates being built.
Jiangmen Shipyard. Five unidentified surface vessels being built.

Why This Matters
China’s immediate and most apparent goal is the seizure of Taiwan and its integration into “One China.” Xi has other ambitions for China though. Xi wants the PLA to be a world-class fighting force by 2027 (in time for the PLA’s 100-year anniversary), and he wants them that way so they can reach parity with the United States.
Xi thinks if China can out-compete the U.S. military in the Pacific, it can dominate the region and launch global projects more effectively. One way China will do this is by dominating and controlling the maritime activity in the South China Sea.

U.S. Marines Conclude Bilateral Exercise Resolute Dragon 24 With Japan
On 7 August, the Marine Corps and Japan concluded exercise Resolute Dragon 24. 3,000 Marines and sailors trained along the Japanese Self-Defense Force (JSDF).
RD24 ran from 28 July and took place across Japan, to include main islands Honshu and Kyushu as well as Okinawa and some outlying southwest islands. The Marines deployed an AN/TPS-80 Ground/Air Task Oriented Radar on Yonaguni island. The island is Japan’s closest piece of territory to Taiwan.

Why This Matters
RD24 is an important exercise for American and Japanese forces to test their bilateral readiness. Japan is one of America’s core partners in the Pacific, and that security relationship is only growing.

Taiwan To Boost Defense Spending
On 8 August, Taiwanese President Lai Ching-te proposed a $19.8 billion dollar defense budget for next year. Radio Free Asia estimates that being 20% of Taiwan’s projected revenue for 2025. Despite their defense spending increasing every year since 2017, this would be Taiwan’s largest investment into defense to date.
The proposal awaits approval by the Taiwanese legislature. Their deadline is 1 December.
Why This Matters
Taiwan is firmly committed to resisting a Chinese invasion. PLA incursions and exercises around Taiwan have become more frequent. President Lai’s presidency began with the PLA surrounding the island as a show of force.
