Why Should We Care if China Dominates Maritime East Asia? | with Brent Sadler

If China controls maritime East Asia, what would that mean for Taiwan, the Philippines, Japan, global trade, and U.S. security?In Episode 163, Ray Powell and Jim Carouso speak with retired U.S. Navy Captain Brent Sadler, a career submariner, former U.S. defense attaché in Malaysia, Heritage Foundation Senior Fellow and author of two books: U.S. Naval Power in the 21st Century and Naval Power in Action: Seizing the Initiative in the New Cold War with China.Sadler’s answer is blunt: China is exercising growing control over maritime East Asia, as Beijing has spent decades building the military, commercial, and political leverage to do exactly that. He says this is not just a question of aircraft carriers, missiles, and hull counts, but also about China’s strategic commercial footprint in ports, shipping and repair infrastructure, distant-water fishing fleets, maritime militia, and the China Coast Guard.Ray and Jim ask what it means that China’s coast guard vessels are operating east of Taiwan. Are these deployments preparation for a possible blockade? Why are fishing fleets moving in organized formations? And how could Beijing use gray-zone coercion to change the status quo before anyone agrees that a crisis has begun?The conversation also examines the recent China-Russia naval exercises and potential for submarine technology transfer, Russian pressure on Japan around the Kuril Islands, and Beijing’s efforts to turn even limited naval interactions with countries such as Indonesia into political and propaganda victories. Sadler explains why Southeast Asian leaders’ rhetoric must be weighed against what matters on the water: maritime rights, military exercises, commercial ties, and freedom of navigation.Finally, Sadler assesses the military balance approaching the much-discussed 2027 window of war concerns, China’s Taiwan contingency preparations, gaps in America’s carrier presence in the Indo-Pacific, U.S. shipbuilding deficits, the future of unmanned vessels, and what Ukraine’s drone war may mean for Taiwan and regional partners.Sadler’s larger warning is that maritime control is no longer just a contest of fleets, but a contest of coercion, commerce, access, and political will; one in which Beijing can test regional governments, reshape behavior below the threshold of war, and learn whether America and its allies will respond before temporary pressure becomes a permanent advantage.Follow Brent Sadler at the Heritage Foundation, on LinkedIn or on X, @brentdsadlerFollow us on X, @IndoPacPodcast, LinkedIn or FacebookFollow Ray on X, @GordianKnotRay, or LinkedInFollow Jim on LinkedInSponsored by BowerGroupAsia
